What Fish Can Live with Goldfish? All You Need to Know

Knowing What Fish Can Live with Goldfish? is a great place to start if you are prepping up to allocate news buddies for your goldfish. While there are several creatures to choose from, not all fish make compatible goldfish tank companions.

In fact, making the wrong decision can often lead to serious consequences. Therefore it is absolutely critical to deduce a detailed listing when deciding on the potential tank mate for these naturally gregarious creatures. This also ensures a healthy and thriving environment for your goldfish. 

However, there is no simple answer to the question of what fish can live with goldfish. Each variety of fish has its own set of requirements. Some fish prefer warm water, while others prefer cold; some are saltwater fish, while others could never survive in the ocean and flourish better as freshwater fish.

Therefore, in reality, moving ahead ( taking various aspects into consideration) and compiling a list of tank mates is far more difficult for goldfishes than creating a list for betta fish. Because you will definitely want all of your fish to be healthy and happy, choosing tank mates who enjoy similar tank settings is essential. Let’s talk discuss how you can easily locate the best tank companions for your goldfish!

What Fish Can Live with Goldfish?

Goldfish (Carassius auratus) is a group of genial animals that are quite interactive when kept in groups. For most fish enthusiasts, the discussion revolving around what fish can live with a goldfish (Carassius auratus) is typically a source of great dubiety.

What Fish Can Live With Goldfish

However, this uncertainty is rightly placed as listing the best goldfish companions takes careful consideration. Several parameters must be considered. Listed below are some basic parameters to follow when deciding on the potential tank mate for your goldfish:

  • White cloud mountain minnows, danios, and Hillstream Loach are all good goldfish tank mates for smaller aquariums. In larger aquariums, acceptable tank mates for goldfish may include Murray river rainbow fish for variety.
  • Maintain tank mates that can survive in the same conditions as goldfish. Goldfish prefer colder temperatures ranging from 50 to 70°F and can live at room temperature without the use of a heater. 
  • Select tankmates that will be able to survive on a goldfish-specific diet. If you add a tough predator that requires a meaty feed, the goldfish may get too much protein and become constipated.
  • Check out for aggressive fish that will prey on your goldfish. Goldfish are generally placid and playful animals that will not flourish in the presence of aggressive barbs, African cichlids, and other large cichlids.
  • Small and spiky fish should be avoided. Goldfish like exploring and putting anything they come across in their mouths, which includes a substrate, food, plants, as well as other fish. For the most part, avoid any species that are small enough to fit in your goldfish mouths; therefore, keep the maximum size of a full-grown goldfish in mind when choosing tank mates. Watch out for tiny spined fish, such as otocinclus or cory catfish, which could become entangled in a goldfish’s gill plate if swallowed.
  • To ensure that all fishes have enough food and swimming space, it is better to keep goldfish with tank mates that possess equal swimming ability. Consider your goldfish’s speed. The common goldfish (also known as the single-tailed or comet goldfish) is a quick swimmer who is prone to consuming things they shouldn’t. Because fancy goldfish are slower, they are more likely to be bullied by other fish. Therefore this information assists in selecting compatible tank mates for both the given varieties. 
  • Goldfish with long fins should not be kept with fish that nip fins, such as tiger barbs. The oddest goldfish kinds, such as the Celestial, should be maintained with their own species since they may have difficulty locating and competing for food when housed with other types of fish with greater swimming abilities.

Tank conditions for fish to live with goldfish

Goldfish, Fish, Aquarium, Underwater, Fishbowl, Water

Often fishkeepers face the dilemma of selecting fish that get along with their goldfish. While we know for a fact that certain combinations work or do not work in most cases, many others can go either way based on a variety of conditions.

When choosing fish to live with your goldfish, keep the following tank parameters in mind:

  • Capacity Of The Aquarium And Filtration: Before you start browsing through the list of potential tank mates, you’ll need to assess the conditions of your current aquarium. This assists in ensuring you have enough room for new fish and a filtration system capable of handling the added workload. Most fish want space (the more area they have, the better they get along). Whereas when fishes are crammed into a small space, they become agitated and more inclined to fight with their tankmates. The lowest aquarium recommended for any species of mature goldfish is a 20-gallon tank, with an extra 10 to 20 gallons of space for each additional goldfish. A little quick calculation can reveal how much additional space you have and help you cut down the list and number of potential buddies!
  • Maintaining the required temperature: Goldfish are freshwater fish that prefer temperatures ranging from 65 to 80 degrees Fahrenheit; thus, fish that live with goldfish should enjoy this setup as well. In general, goldfish thrive in aquariums with no additional heating sources. As a result, species that demand an extremely warm tank setup should be out of the listing.
  • Consider the decor and arrangements of your tank as well. While goldfish will devour and uproot live plants, utilizing plastic plants to create hiding places for other fish, shrimp, and snails is one approach to boost the likelihood that a certain mix will work in your tank. Creatures can hide from your voracious goldfish using rocks, logs, and other decors!
  • Examine the Setup and Filtration Systems: Goldfish are voracious eaters who will spend their time wandering your tank in search of food. They will consume anything they can get their hands on. As a result, they generate a lot of biowastes and require a high-quality multi-stage filtration system to maintain their tank clean and neutralize poisons. They dislike strong currents and avoid them. Before adding companion fish to your tank, ensure that your filter and setup can manage the extra load and are appropriate for that species as well as your goldfish. Single tails take up the full tank but like enough space to swim, and fancies are restricted by their physical characteristics. You might be able to find a companion who prefers a location that your goldfish avoids!

The Best Goldfish Tank Mates

With the fundamental ground rules in mind, let us explore the top tank mates that have been determined to be compatible with goldfish and coexist peacefully:

Dojo Loach 

Dojo Loach Care 101 (aka Weather Or Pond Loach)
  • Scientific name: Misgurnus anguillicaudatus
  • Temperament: peaceful 
  • Size: 6 to 8 inches
  • Average tank size: 55 to 75 gallons 
  • Care level: Beginners 

When it comes to goldfish tank mates, these fish, sometimes known as weather loaches, are an excellent choice. Their bodies are slender and sausage-like, with small fins. Some barbels around the mouth aid in their search for food, while the little pectoral aids in navigation.

Dojo Loach enjoys swimming around, burrowing in the gravel, and eating whatever you offer them. These amiable critters thrive in cold water and are a common addition to goldfish aquariums.

These fish are not at all aggressive. Even when confronted with aggressive behavior, dojo loaches would rather hide and eat than engage in a battle.

Despite their bigger size, they are frequently available for the low price of $5 for the standard form and $10 or more for the specialty gold or albino varieties.

 White Cloud Mountain Minnow

White Cloud Mountain minnow
  • Scientific name: Tanichthys albonubes
  • Temperament: Peaceful 
  • Size: 1.5 inches
  • Average tank size: 10 gallons
  • Care level: Beginners 

If you just have fancy goldfish, cold water minnows could be an excellent alternative. They’re economical, like school together, and only grow to be 1.5 to 2 inches long.

They’ll be considerably smaller when you first get them, so consider growing them out (and possibly breeding them) before putting them in your goldfish tank.

And though these fish can fit in goldfish mouths, they’re far faster and nimbler than slower fancy goldfish, making them tough to catch. (In the event that one is accidentally eaten, the goldfish are not harmed.)

White cloud minnows come in a variety of colors (such as normal or gold), but avoid longfin versions because their extended fins will slow them down and increase their chances of being caught.

Giving White Cloud Mountain Minnow a shot is an excellent choice because they bring intriguing action to the aquarium as well as fantastic enrichment for the goldfish to observe and chase.

 Hillstream Loach

Hillstream Loach Care Guide: Tank Mates, Size, Breeding...
  • Scientific name: Sewellia lineolata
  • Temperament: Peaceful 
  • Size: 2 to 3 inches
  • Average tank size: 20 to 50 gallons
  • Care level: Beginner-Intermediate

These peculiar critters possess a distinct appearance. Because of their large fins, many people mistake them for little stingrays. Hillstream loaches, while officially belonging to the loch family, behave like plecos.

They spend their days eating algae while adhering to glass and polished surfaces. They like to remain out of sight and out of mind since they are inherently peaceful. If they get a little bold, hillstream loaches are perfectly capable of escaping goldfish.

They won’t generally retaliate, either. The hillstream loach is well adapted to the colder temperatures seen in goldfish habitats. If the conditions are favorable, they can even make good pond fish.

Zebra Danios

Danio Rerio - Zebra Danios
  • Scientific name: Danio rerio
  • Temperament: Peaceful 
  • Size: 2 to 2.5 inches
  • Average tank size: 10 gallons
  • Care level: Beginner

A species of small, fast-moving fish, Zebra danios, can flourish in the same temperature range as goldfish. Not only that, but they’re also quite peaceful. Zebra danios are fishes that possess blue and yellow stripes running from the nose to the tail.

Their anatomy is covered in an iridescent sheen that shimmers and catches the light as they dart around the tank, making them incredibly appealing to look at.

Though these fishes are small enough that adult goldfish can eat them, yet they are swift swimmers who can readily dodge any goldfish that tests its luck. Most goldfish, on the other hand, will not even try to consume them.

Typically zebra danios cluster in groups, which goldfish find quite unappealing. These critters also like to dwell near filters and bubble walls. Furthermore, providing the danios with some tall artificial plants so they can hide if necessary, might be a good idea.

Hoplo Catfish

Hoplo Catfish Facts
  • Scientific name: Megalechis thoracata
  • Temperament: Peaceful 
  • Size: 5 to 6 inches
  • Average tank size: 55 gallons
  • Care level: Beginner-Intermediate

The hoplo catfish is a South American native. However, because of its overall resilience, it can survive in colder temperatures. This is a charming freshwater catfish with appealing markings, a calm demeanor, and the capacity to adapt to a variety of situations.

Hoplo catfish are quite reclusive and dislike the noise and bustle of busier aquariums (which is why they make ideal tank mates for goldfish). That is not to imply that they will not thrive in community tanks.

But, more often than not, you’ll find them hiding beneath logs or among the bushes. The good news is that hoplo catfish feed throughout the day. As a result, you will occasionally see them foraging for food.

Rosy Barbs

Rosy Barb Fish in an Aquarium
  • Scientific name: Pethia conchonius
  • Temperament: Peaceful 
  • Size: 6 inches
  • Average tank size: 20 to 30 gallons
  • Care level: Beginner

Rosy barbs are brightly colored freshwater fish that thrive in somewhat cooler conditions. They have a lovely reddish hue that goes well with the goldfish. Best of all, they’re calm and get along with most fish.

The lone exception is shoaling behavior. Rosy barbs are friendly organisms that live in groups of at least five of the same species. Without that safety net, rosy barbs can devolve into hostility and territorial behavior.

Rosy barbs are also resilient and low-maintenance. They are easy to keep and will consume flakes, small pellets, and most frozen foods.

Because they are rapid swimmers, you must ensure that your goldfish can acquire some food before your barbs swoop in and devour it all. They’re a terrific size (with a maximum length of 6 inches) that’s far too huge for the voracious goldfish to swallow up.

Just ensure your tank is big enough for both species because they will need a lot of space to thrive.

What Makes An Ideal Goldfish Tank Mate?

While goldfish are attractive and iconic enough to relish on their own, they also make excellent additions to communal aquariums. Goldfish, which are peaceful and lively, thrive wonderfully in a multi-species setting.  

However, creating a goldfish community habitat is not as simple as it appears. Choosing appropriate goldfish tank mates is the most difficult component of developing a thriving colony with these freshwater fish.

Veil Tail, Fish, Goldfish, Swim, Aquarium

As a result, there are various characteristics to look for in potential tank mates. So, let’s reflect on what makes a specific fish or invertebrate a good goldfish tank mate.

Temperature Preference

The recommended temperature range is the first thing you may use to filter down your search for goldfish tank mates. The best partners are those whose ideal temperature range overlaps with the temperature range of your goldfish aquarium.

Goldfish are classified as cold-water fish in the fishkeeping world. These fish, however, require somewhat warm waters to remain healthy. However, there is a significant disparity between a goldfish’s comfortable temperature range and that of other popular species.

Goldfish, you see, are native to cooler mountain streams. Goldfish can normally live in temperatures ranging from 65°F to 75°F.

Some cultivars prefer even colder conditions! In general, goldfish thrive in aquariums with no additional heating sources. As a result, species that demand extremely warm water are simply out of the question.


This is a crucial characteristic to consider when looking for the perfect match. When it comes to goldfish tank mates, medium-sized fish are the way to go. It’s best if it’s three to four inches long.

However, generally, the potential buddies should be the same size as your goldfish. This is because Goldfish are voracious feeders that will devour anything they can get their hands on.

Goldfish, as omnivores, are equally content on invertebrates and smaller fish as they are on their commercial diet!

As a result, to avoid inadvertent feedings, keep tank mates the same size as your goldfish. Other species should be large enough to avoid being swallowed by your goldfish.

Larger fish, on the other hand, can also cause complications in a goldfish aquarium. For example, It is not suggested to maintain angelfish with goldfish because your goldfish may chase and torment them.

Goldfish, especially single-tails, can’t resist nibbling on those lengthy fins. Furthermore, large size may also lead to lesser space in the tank for free swimming and settlement by the different residing species. 

As a result, it’s preferable to pair up with tankmates who are the same size and have short fins.


Goldfish are calm, non-aggressive fish that do not establish territories or protect their habitat from other fish. Therefore, it is preferable to avoid any species that has a penchant for aggressiveness.

Goldfish cannot defend themselves against high-strung fish. This is especially true for exotic and slow-moving kinds. Adding a hostile or territorial fish to the mix may also generate unnecessary stress for both parties.

Goldfish prefer to occupy the entire tank. They have no concept of boundaries, which could be an issue for fish who wish to claim their territory. The frequent back-and-forth is unhealthy for any fish engaged, so keep personalities as similar as possible.

Activity Levels

Tankmates with similar speed and agility in the water make the greatest tank mates for your goldfish colony. This will not only help you avoid strain, but it will also help you avoid injuries. Factually speaking, there are over 200 different types of goldfish available. Some move slowly, while others are comparatively more agile. 

Slim-bodied single-tail goldfish are rapid swimmers who would mob any fish that is slower than them. They might even outcompete them for food!! 

Whereas if maintained alongside fast-swimming buddies, fancy goldfish may experience the opposite difficulty. The fancy goldfish frequently require special floating diets to fit their ponderous swimming style, and quick and efficient fish may consume all of their food.

This is why only a few species of tetras and goldfish can exercise in the same aquarium as this variety of goldfish. 

Maintaining a consistent baseline is the key to keeping the peace!!

What Fish Cannot Live with Goldfish?

While we have identified a number of species that align well with your goldfish, there several others that should be simply avoided. None of the following species are the appropriate answer to what fish can live with a goldfish:

What Fish Can Live With Goldfish?
  • Cichlids. Cichlids and goldfish do not get along as cichlids are a species of fierce predators. While Goldfish themselves are predatory species, however, they are not extremely aggressive and would make easy prey for a more aggressive cichlid.
  • Molly fish, Guppies, Gouramis, and a number of other species with rigorous warm temperature needs should also be avoided. 
  • Bettas– betta fish require warmer habitats and, as highly aggressive fish, will most likely attack your goldfish. They may strike the goldfish or, at the very least, nibble on their fins.
  • Tetras- Tetras not only like warmer water, but they also have a difficult time coexisting with chaotic goldfish. It’s not always easy to maintain the water balance in a goldfish tank, and tetras sometimes find it difficult.
  • Common goldfish with fancy goldfish- You should also think long and hard before maintaining different goldfish species in the same tank. Multiple fancy goldfish will obviously get along OK, but keeping fast-swimming common goldfish alongside long-finned fancy goldfish is a red flag. Fancy goldfish are more delicate than regular goldfish, and there may be a power struggle for food, which your fancy goldfish will not get along with.
  • Corydoras- According to studies, corydoras are prone to sucking the slime coat from goldfish. They can also be rather aggressive, which should be avoided when searching for a potential tank mate.
  • Common plecos — they also suck the slime off goldfish, exposing them to the threat of infection.

How Many Goldfish Should You Keep in Your Tank?

Goldfish come in a wide range of colors and variations, but they all demand the same level of attention and devotion. Despite popular perception, goldfish, or bowl-dwelling fish as they are commonly known, are not easy to care for.

Goldfish, in fact, can grow to be pretty large. However, Its final size is generally determined by its containment. Take, for example, pond goldfish; because they live in a larger space than their counterparts in indoor tanks, they can develop faster and larger.

Goldfish, Aquarium, Underwater, Tropical, Pet, Swim

In general terms, each goldfish requires at least ten gallons of water. In a 20-gallon aquarium, ideally, no more than one fancy goldfish should be kept. As a result, a pair of goldfish will require an aquarium with a minimum capacity of 40 gallons of water.

This arrangement is primarily owing to the fact that Goldfish can grow to measure as much as 6 inches or more, depending on the species.; therefore, this necessitates a huge setup.

Furthermore, goldfish produce a lot of bio-waste quickly, and the larger tanks help keep the water cleaner by providing enough space for the fish to swim. 

Besides, under optimal conditions, Goldfish have long and healthy lives. Larger spaces accompanied with access to live foods that meet their nutritional needs help these fishes to thrive.

It is recommended to keep only as many goldfish as your aquarium can comfortably hold because goldfish grow indefinitely. Your aquarium will fare better if you maintain fewer goldfish in it. 

A fish tank with small dimensions confines and restricts the easy flow of these fishes. Its activity level decreases due to a lack of room, resulting in stress and stunted growth. The goldfish will live, but it will not thrive.

While on the other hand, if you put the same goldfish in a larger enclosure, it will be able to swim and exercise more freely. As a result, the fish will be a lot happy and healthier.

Furthermore, you should add at least ten additional gallons of water for each new goldfish to avoid overcrowding. Therefore, it is preferable to purchase a large tank sooner rather than later.

If your fish outgrow their enclosure, you’ll have to upgrade. What’s more, with the right enclosure, your goldfish will have enough space and resources to thrive.

How Often Should You Feed Goldfish? How Much?

If you want to give your goldfish the best possible care, you need to understand how frequently and how much they should be fed is the right amount to settle on.

Providing them with inappropriate amounts (too much or too little food and at the wrong times) can result in a variety of issues that you don’t want to deal with.

Fish, Goldfish, Underwater, Water, Sea, Orange, Yellow

According to the normal rule, you should feed your goldfish about 2 or 3 times every day until they are one year old. Once your goldfish has crossed the mark of a year, you should adhere to only feeding them once a day. 

In terms of quantity, below are two typical recommendations to assist you in determining the appropriate amount of goldfish food: 

  • Stick to the two-minute standard to figure out how much to feed them. Simply said, you should not feed your goldfish more than they can consume in two minutes. Give your goldfish a portion of food that it can consume in under two minutes.
  • Give the goldfish an amount of food equal to the size of its eye.

However, there isn’t a direct answer to how often to feed your goldfish. In fact, there are a variety of reasons why you would want to change the Feeding frequency and schedule. Additionally, the type and quantity of goldfish food you feed your goldfish are also critical. 

These parameters have a big impact on how often you should feed your goldfish.

  • Stocking: The amount of water available to dilute toxins produced by excess nutrition influences how often goldfish should be fed. Your fish will create more waste if your tank is overcrowded. This increases the risk of polluting your tank’s water, so be careful not to overfeed. Having numerous fish in the same tank also means that they will fight for food. When feeding, pay great attention to ensure that each fish gets adequate food (and that no fish eats too much!). You reduce the risk of contaminating your water by keeping the quantity small. Furthermore, by feeding more frequently, you may be able to properly target individual fish and ensure that everyone gets their fair portion.
  • Age: As previously stated, we recommend feeding younger goldfish (those under the age of one year) more frequently than adult goldfish. Because goldfish grow the fastest in their first year of life, they require multiple little meals throughout the day. A series of little meals spaced throughout the day promotes more growth than a single large meal. However, it is critical to feed just very little amounts. Only a tiny little bit of food is required, particularly when frequency includes two to three times a day. 
  • Temperature: When the temperature outside goes below 50 degrees F in the winter, goldfish may only need to be fed once a month. As their metabolism slows, hibernating goldfish have difficulty digesting food, which can result in the food rotting in their gut and causing illness.
  • Spawning: If you want your fish to procreate, you’ll need to get them into “breeding conditions” by giving them numerous larger meals throughout the day (a more intense water change schedule accompanies this). The more food the fish have, the more eggs and milt they produce.

Is it necessary for goldfish to have tank mates in order to be happy?

While we have been pondering what fish can live with goldfish, let us reflect on whether it is really necessary for goldfish to have tank mates to be happy?

Well, factually speaking, Goldfish thrive in the presence of their tankmates since they are naturally gregarious creatures. These fish require social contact to survive. They get bored in the tank if they aren’t engaged.

Fishes, Goldfish, Freshwater Fish, Carp Fish

While it is impossible to pin down how your goldfish feels while swimming around the tank exactly, you can sense there might be requirements for a tank mate due to certain peculiar behaviors.

In general, when goldfish are lonely and bored, researchers believe they may begin to exhibit negative behaviors. A bored goldfish will be less active than one that is content with its surroundings.

The lethargy of solitary goldfish is common. This behavior resembles depressed symptoms in humans and high-cognitive animals such as canines and rabbits. Goldfish depression is a term used by experts to describe this type of behavior.

The bottom line is that you should never underestimate a fish’s mental abilities. They, too, have social requirements.

what fish can live with goldfish in a pond?

Goldfish are relatively small in comparison to other commonly domesticated pond fish. For decades, if not longer, people have raised goldfish in ponds. Every pond enthusiast desires to have a robust goldfish community in an ecologically balanced pond.

Water, Fish, Japan, Carp, Animal, Freshwater, Goldfish

When reared in captivity, these fish grow to be between 4 and 12 inches (10 cm) long. This makes goldfish an excellent choice for those with a small pond and a desire to invest in smaller fish.

Furthermore, Goldfish can also be maintained among a wide variety of species without fear of aggressiveness on their part, particularly because of their peaceful nature. 

However, many fish species cannot safely share a pond with goldfish due to several reasons incompatibility of requirements, differing disease immunity, and the risk of predation. 

Having said that, when kept with other appropriate Pond Mates, Goldfish show a plethora of advantages, including the ability to live for more than a decade ( especially when surrounded by non-aggressive fish and maintained with proper conditions).

A well-chosen species combination will not only look captivating but will also provide a variety of ecosystem services to your pond. 

Here are some wonderful options to consider if you’re exploring new buddies for your endearing goldfish.

Bristlenose Pleco 

The Bristlenose Plecos (Ancistrus cirrhosis) constitutes an interesting species of algae eaters. These mustachioed janitor fishes are calm and will gravitate to the sediments in your pond.

In an outdoor pond, fine gravel, adequate water flow, and a powerful filtration system are sufficient setups to keep this pleco species happy.

The Bristlenose Pleco is known in the pond hobby sector as one of the tiniest armored catfish species, rarely exceeding a length of 5 inches (12.7 cm) in decorative setups. Some pond enthusiasts may be hesitant to keep plecos in the same pond as goldfish.

This is mainly due to the fact that hungry plecos will tend to grip on a goldfish’s slime coat to get whatever nutrition they can. However, because this type of conduct is completely avoidable, it is not a pressing issue.

Simply feed your Bristlenose Plecos food that sinks to the pond bottom (sinking wafers, brine shrimp, and other protein-rich foods). If you’re worried about your goldfish eating all of the food, throw flakes on the other side of the pond to divert them.


Ornamental Koi (Cyprinus rubrofuscus), which are members of the carp family, are calm fish that flourish in ponds with goldfish.

Because much larger individuals of Cyprinus rubrofuscus species ( 5 – 10 times the length of goldfish) may occasionally be responsible for the extinction of small goldfish, the size disparity between koi and goldfish must be balanced. 

Koi and goldfish are fairly compatible in terms of pond requirements. They may coexist peacefully and, on occasion, will even breed to create sterile offspring!

The little barbels and characteristics with intermediate lengths distinguish these hybrids (between koi and goldfish).

Occasionally, either species will eat the eggs and larvae of the other, although this is a common occurrence in ponds and is frequently a good way to keep populations in check.

Longfin Rosy Barbs

Barbs are generally not suggested as goldfish pond mates, although a few species are tranquil enough to make good friends. When introduced with schooling mates, Longfin Rosy Barbs (Pethia conchonius) are less prone to nibble the fins of goldfish.

Remember to domesticate more than a handful of these species in your pond. This keeps them occupied with one another, and they’re less likely to bother the rest of your pond fish if they stay in their groups.

Because of their sparkly pink coloring, Rosy Barbs are an extremely appealing addition to a goldfish pond. As outside pond fish, they are rather small, reaching only 6 inches in length.

Provide your Rosy Barbs with a set-up that mimics their natural habitat to keep them satisfied. They will thrive in an environment with plenty of aquatic vegetation, plenty of swimming room, and a gentle current.

Keep in mind that if you want these fish to live longer (say for five years or more), you may need to move them to an indoor setup during the winter.

Other Goldfish

Not all species of Goldfish can be kept in the same pond. Broadly this species of fish is distinguished into two types of goldfish: Common and Fancy Goldfish.

The general characterization depicts that the common variety of goldfish possesses a keen resemblance to the wild goldfish: however, the coloring is greater in the common variety. On the other hand, longer fins and odd body forms are generally observed in Fancy Goldfish.

Because of their elaborate set of fins, fancy goldfish swim more slowly. Furthermore, the common variety outsmarts the Fancy goldfish for food when maintained together. 

Fancy and common goldfish can also breed in the same pond because they are both members of the same species. This results in fish that revert to their wild-type form, erasing the generations of breeding that produced the Fancy Goldfish.

Weather Loach 

Weather loach (Misgurnus anguillicaudatus), a fascinating bottom-dwelling fish that resembles an eel, is also known as weather, dojo, or pond loach. It’s a sturdy species that prefer cold water, which makes it ideal for pond rearing. 

Weather loaches are a good match for goldfish since they are both active and gentle. They are most cooperative when grown in groups, and they only scavenge for organic matter. They can also quickly become used to goldfish food.

They are generally low-maintenance pond additions that may even endure poor water conditions. They grow to be 12 inches long on average and can live for up to ten years with a little love and care. 


Goldfish, Water, Pond, Aquatic Animal, Aquarium, Swim

With such a wide range of possibilities of compatible tank mates for goldfish, the listing constitutes a brimming chart and is often a heated topic of debate. Pre-eminently, the best goldfish tank mates have a lot in common.

You basically seek freshwater fish that are calm, do well in cool water, aren’t extremely energetic, and are of a reasonable size. 

Nonetheless, the greatest tank mates will be determined by your goldfish’s breed as well as the size and setup of your aquarium.

To increase your chances of success, pay special attention to your tank’s capacity and change the decor and plants to provide each species with its perfect and desired environment. The species on our list meet these requirements, and we’re confident you’ll enjoy having them as your goldfish buddies.


What is the required tank size for two goldfish?

The recommended goldfish tank size, according to the general rule, for two goldfish is 42 gallons for two Common goldfish (that’s 30 gallons for the first fish and 12 more gallons for the second fish). In the case of fancy fish, 30 gallons is required for two fancy goldfish (that is 20 gallons for the first fish, followed by another 10 gallons for the second).

Can 2 goldfish live together?

Yes, they can. In fact, it is suggested to have at least two goldfish in an aquarium for company and activity. Depression and lethargy can occur in solitary fishes. Goldfish are normally not aggressive so that they can be kept with other fish; however, make sure both of your goldfish are of the same species, as common goldfish do not get along with fancy goldfish species.

Why do goldfish push each other?

Sometimes you may notice two goldfish pushing each other. The major causes of the two pushing at each other, swimming in circles, or chasing each other around are as follows:
Sickness: When one is sickly or weak, the others may make matters worse by attacking or pecking on them. 
Territorial conduct 
Increased Stocking Densities 
Competing for food
Due to Playful temperament
