Goldfish and Angelfish have an exotic and sophisticated elegance in their physical appeal, but can you keep angelfish and goldfish together? With a peaceful, social, and friendly nature that so many new aquarists find extremely attractive and bold, you might think they both are a match made in heaven.

This article will go over the practicalities of keeping angelfish and goldfish. If you are wondering ‘can goldfish and angelfish live together?’, note that they are from different fish families. Therefore they have very different origins that have a substantial impact on their needs.

Can Goldfish And Angelfish Live Together?

Angelfish require much warmer water temperatures than Goldfish

Goldfish and angelfish alike are favorite fish for both beginners and more advanced aquarists. They have a general pleasant nature and attractive appearance that makes them interesting, and aesthetically pleasing to keep.

It may be ever so tempting to house these two species together for their exquisite beauty and similar temperaments. However there is much to discover regarding the care requirements of goldfish and angelfish. You can’t just judge on appearance, but must instead look at their nature to fully comprehend their compatibility as tank mates.

Regarding the species and care information, it is clear that angelfish and goldfish come from different regions. They have vastly different water parameter requirements, even though in a few aspects they are similar. So, can angelfish and goldfish live together?

With that said, it is NOT a good idea to keep goldfish and angelfish in the same aquarium because of the following reasons:

  • Temperament

Goldfish enjoy the company of other Goldfish, though they are not schooling fish. Whereas Angelfish prefer to be kept in groups that will pair off as adults. Both Angelfish and Goldfish are peaceful in general, though Angelfish become very territorial when breeding. Goldfish are similarly prone to eating smaller fish and will have no trouble eating smaller Angelfish, or Angelfish fry.

  • Aquarium Conditions

Angelfish require much warmer water temperatures than Goldfish, and if living together either the Goldfish or the Angelfish will be in sub-par water temperatures. This can cause illness and in some cases death. On the other hand, they can tolerate similar pH levels. Angelfish prefer a well-planted aquarium with much vegetation and preferably indirect and filtered light. Whereas, Goldfish enjoy more open spaces and light.

  • Tank Size

Generally Goldfish need a much larger tank than Angelfish, and can survive in outdoor ponds. Angelfish can never survive in an outdoor pond.

  • Tank Maintenance

Goldfish produce enormous amounts of waste in comparison to Angelfish. Angelfish are extremely sensitive to dirty water conditions. They also may not be able to handle the strong currents of a powerful filtration system as required by Common Goldfish.

  • Diet

Goldfish are generally more prone to digestive issues than Angelfish. Furthermore, Angelfish need a higher protein-based diet, which can be problematic during feeding time. On the other hand, they are both omnivores with similar dietary requirements.

Thus, there are many challenges with housing Angelfish and Goldfish together. One of the greatest issues is water temperatures. The other is water conditions which will affect either one of the species negatively.

How Can I Keep Goldfish With Angelfish?

In theory, there have been emergencies where yu need to house goldfish and angelfish together, though this arrangement is only temporary and never a permanent solution.

If necessary, you can follow these steps to safely house Angelfish and Goldfish together for a short period:

  1. The temperatures of the tank should be maintained at the lowest possible, tolerable temperature for Angelfish, which is between 20° C to 24° C (68° F to 74° F).
  2. Try to keep Goldfish with a group of Angelfish as Angelfish become territorial when breeding.
  3. Feed Goldfish and Angelfish in separate areas of the tank as Goldfish can be overeager during feeding time.
  4. Try to feed Angelfish in the mid-section of the tank and Goldfish on the surface.
  5. Keeping small young Angelfish with larger Goldfish, or small young Goldfish with Large adult Angelfish is ill-advised, as both species may resort to eating smaller fish.

Best Tank Mates For Angelfish And Goldfish

In conclusion, goldfish and angelfish do not make suitable tank mates. Therefore it is best not to house them together. There are a few much better options in tank companions for both Goldfish and Angelfish, that will thrive together:

Regards goldfish species compatibility with other fish species, the best tank companion for a Goldfish is another Goldfish. Keep in mind that it is best to keep Common goldfish species together, and not with Ornamental Goldfish species.

This is as they are much more fragile and have long flowing fins that can be inviting to Common Goldfish. Regardless, there are still a few other species that can thrive in the same environment as all Goldfish:

  • Rosy Barbs.
  • Giant Danios.
  • Banded Corydoras.
  • Hillstream Loaches.
  • Larger Snail Species.

Compatible Tank Mates For Angelfish

Like Goldfish Angelfish are social and tend to shoal, thus similar peaceful fish species can live with Angelfish. It is however vital that you stick to non-aggressive species and small slow species that may become prey to Angelfish. Angelfish mostly become aggressive and territorial when breeding, and changing around a few things in your tank will ideally calm down the situation.

A few good tank mates include;

  • Bottom feeding Corydoras Catfish or Plecos.
  • Harlequin rasboras.
  • Neon Tetras.
  • Cherry Barbs.

Care Requirements For Goldfish And Angelfish

To better understand the compatibility between Angelfish and Goldfish it is vital to know what their individual needs are. The short answer to ‘can angelfish and goldfish live together’ is no. However, there are many reasons why this is.


A tank of around 20 – 30 gallons should suffice for one or two Goldfish to be able to grow to a mature size.

Starting with Goldfish, are hardy aquarium and pond fish. They are tolerant and prefer cooler water temperatures. Likewise, they are generally very easy to care for and ideal for beginners, with little fuss.

The exception is some ornamental Goldfish species that are more sensitive. Goldfish are relatively large and will grow to their full size if they have with enough space. According to studies a Goldfish will only grow as much as the size of its environment allows. Thus, Goldfish living in small aquariums will stay smaller, though it’s best to give them maximum conditions.

  • Aquarium

Goldfish do not need to live in groups though they do enjoy the company of other Goldfish. A tank of around 20 – 30 gallons should suffice for one or two Goldfish to be able to grow to a mature size. Water temperatures of between 65 to 75 °F (18 to 24 °C) are preferable for a thriving Goldfish, with pH levels of between 6.5 to 8.0. Goldfish can live in a pond or unheated aquariums given that the temperature does not drop below these parameters.

In an aquarium, a fine or medium gravel or sandy substrate is ideal. This should include rocks, caves, PVC Pipes, and other types of décors as hiding spots and enrichment. Synthetic or live plants are ideal. More robust Live plants are suitable for Goldfish that may tend to occasionally snack on plants. Keep in mind Goldfish produce plenty of waste, and for such reasons need a good filter that has a moderate current.

  • Feeding

Naturally an Omnivore Goldfish feeds on both plant and meat-based foods. A healthy diet will include quality fish flakes or pellets, blanched green vegetables, and proteins such as blood worms, brine shrimp, or insect larvae. Goldfish are prone to digestive issues as they age so try to include foods lower in proteins, starch, and sugars.

  • Temperament

The Goldfish is a very social, intelligent, and friendly fish. It can become relatively tame and will take an interest in their human companions. However, they are prone to becoming territorial during spawning season and tend to nip at other fish with long-flowing fins.

  • Breeding

Not to go into too much detail, but with proper nutrition and water parameters Goldfish will mature and easily breed in your tank. They are not the best parents and will resort to eating their own young. Thus breeding Goldfish is a delicate, and labor-intensive endeavor. You should only attempt it with knowledge and understanding.


Are freshwater angelfish easy to keep?
Angelfish requires a bare minimum of 30 gallons in tank size per single fish, with 20 gallons extra per additional Angelfish.

In contrast to Goldfish, angelfish are likewise hardy and very easy to keep, though they do need higher, more tropical climates to thrive in.

  • Aquarium

Angelfish require a bare minimum of 30 gallons in tank size per single fish, with 20 gallons extra per additional Angelfish. They thrive in a well-planted tank with open space and more filtered light and need a clear indication of day and night. Water temperatures of between 26 to 30 degrees Celsius (75 – 86 Fahrenheit) are essential and a pH ranging between 6.0 and 7.5 is ideal. As they do not produce as much waste, a hang-on back filter is sufficient, with a lighter current.

As Angelfish do forage on the bottom of their tanks, a smoother, medium-sized gravel is essential as substrate. Generally, a lush and more natural tank environment with live plants and a few hiding spots is best. There should be enough open areas for swimming. When choosing décor and plants it is vital to ensure that they have no sharp edges or rough surfaces, as Angelfish may easily suffer physical damage.

  • Feeding

Though said to be omnivores, Angelfish do prefer more protein-rich foods. They tend to feed from all areas, top, bottom, and center of the tank, and they similarly require fiber in their diet to prevent digestive upsets. A balanced diet of quality flakes or pellets, blanched vegetables, and proteins including bloodworms, brine shrimp, daphnia, ground beef liver, and insect larvae is ideal. Algae wafers are similarly an essential snack.

  • Temperament

With their elegant and peaceful demeanor, Angelfish are still a part of the cichlid family that has a reputation for showing slight aggression. Angelfish are notorious for eating smaller fish, and anything alive that will fit in their mouth. They can become territorial during breeding season, though for the most part, they are known to be peaceful and friendly.

  • Breeding

In comparison to Goldfish, Angelfish are nurturing parents that will take care of their eggs and young. This is the general rule, except for new and more anxious parents that may on occasion eat their eggs or young. Angelfish select a single mate to pair off from a social group and claim a territory that they will protect aggressively if needed to lay their eggs and care for their fry.

An important factor about both angelfish and goldfish is feeding amounts. Goldfish will overeat and become bloated, whereas excess Angelfish food may cause waste in your tank, thus it is vital only to feed enough for them to eat within 2 – 3 minutes, twice a day.

Common Health Issues Found In Angelfish And Goldfish

In terms of common health conditions, Common goldfish tend to be more resilient than Ornamental Goldfish, and Angelfish. Either way, they are mostly all prone to the following typical health issues:

  • Fin Rot

As a result of an injury or Ammonia burns fish may get an infection known as fin rot that spreads throughout the fins and eventually the body. Treat fin fot by separating the ill fish into a clean water tank and using an antifungal or antibacterial solution.

  • Ich

A parasite that causes white spots on your fish, especially the gills, also known as White Spot disease. It is common in poor water conditions and fish under stress. You can treat ich by improving water conditions and separating the sick fish, as it is contagious.

  • Swim Bladder Infection / Dropsy

If noticed that a fish struggles to stay upright or swim it may have an infection in the swim bladder (organ helping fish float), which can either be fungal or bacterial. Depending on the infection you can treat it with antibiotics and quarantine in pristine water conditions, with proper nutrition.

  • Digestive Issues

Angelfish need fiber in their diet to help with digestion. Both Angelfish and Goldfish are prone to digestive issues such as bloating and irritable bowels. Thus you must feed a proper diet with adequate fiber.

  • Dark Ghost Black
  • Albino with no dark pigments

Angelfish have a general size of around 6 – 8 Inches (15 – 21 cm), and with proper care a 12-year lifespan in captivity, and 15 years in their natural habitat.


Goldfish Species Information
Goldfish, scientifically referred to as (Carassius Auratus), are from the Cyprinidae family, and one of the most popular aquarium and pond fish species in the trade.

The common goldfish, scientifically referred to as (Carassius auratus), is from the Cyprinidae family, and one of the most popular aquarium and pond fish species in the trade. Did you know, goldfish originate from Asia? Here, basic silver Carp species produced orange, red, or yellow color mutations initially. However selective breeding created many different species and color variants that specialists divide into Common Goldfish, and Ornamental or Fancy Goldfish.

The Common Goldfish consists of three species, the Common Wild Goldfish, Comets, and the Shubunkin. Common Goldfish generally have a more elongated and slightly compressed body shape with shorter fins. In comparison, Ornamental Goldfish are rounder and fuller in shape, with longer flowing fins and tails. Additionally, they are also slightly more sensitive and fragile than Common Goldfish species. There are over 100 species of Ornamental Goldfish in different shapes, sizes, and colors.

Depending on the type of Goldfish, their size will typically be between 4.7 inches (12 cm) and 8.7 inches (22 cm), with larger sizes of 16 inches (41 cm) recorded. Goldfish have a lifespan of between 5 and 15 years which will similarly depend on the species of Goldfish.

If you were wondering ‘can goldfish and angelfish live together?’ this subsection should show you how they have different requirements.

A few interesting facts about Goldfish:

  1. They are very intelligent and sociable, and similar can be tamed to a certain degree.
  2. Goldfish have a memory span of over three months.
  3. They can recognize faces and can see four basic primary colors.
  4. Goldfish equally have excellent hearing capabilities.
  5. They are one of the most studied fish species in terms of their Vision and Hearing.

To Conclude

It is evident that though Angelfish and Goldfish could essentially survive together, one or the other will not thrive, and can become stressed or ill. Water temperatures are one of the main factors as to why Angelfish and Goldfish are not compatible tank mates.

Frequently Asked Questions

Are my Angelfish Kissing or Fighting?
“Kissing” is pecking behavior usually seen between two males establishing dominance. In the case of a pair, there will be more gills flaring, and the male will nip at her gills and not her mouth.
What Does Tail Slapping Mean?
Tail slapping is a sign of aggression rather than wanting to mate. Usually, a  male and female pair will perform a slight bow when they are flirting with each other, rather than tail slapping.
Are Angelfish Aggressive Towards Discus Fish?
Angelfish are generally peaceful; however, they can become especially aggressive when breeding or during feeding time and may tend to pick on Discus fish.
