Can Angelfish Live Alone?

Angelfish are peaceful fish with a lot of admirable qualities. They are solitary fish but better when you pair them with other Angelfish.

They are slow swimmers and assuredly graceful swimmers and they are very colorful with excellent features.

Can Angelfish Live Alone? Angelfish can quite happily live on their own. They are good at staying alone, but they prefer to be paired with other Angelfish. They can also live with other species of fish provided they have compatible properties.

How Many Angelfish Should You Keep Together?

It is preferable to keep an even number of Angelfish in the tank. This number is because Angelfish are neither a complete solitary nor schooling fish.

They like to move in pairs, so you must always keep the number of fish needed for pairing in the tank.

Whenever there is an odd number of Angelfish in the tank, the odd one out usually suffers from the other pairs and might eventually get killed in the long run. So, if you want to add other Angelfish to the tank, you should always make sure they all add up to an even number, not an odd number.

Can You Keep Angelfish with Other Fish

Angelfish are cichlids, and it is common for cichlids to be aggressive towards one another. Also, Angelfish are slightly offensive, particularly during their breeding season.

Angelfish will live peacefully and comfortably with most other species of fish. When living with fellow Angelfish, they tend to be less aggressive. Their level of aggressiveness only rises in overcrowded tanks or when they are in their breeding season.

Angelfish can also accommodate other species of fish if you meet their accommodation demands. Angelfish can eat anything that fits into their mouth, and since they are carnivorous, keeping smaller fish in the same tank with Angelfish is not advisable.

Also, Angelfish are known to eat smaller fish. It would be best if you didn’t keep smaller fish or fry in the same aquarium as the Angelfish.

Can You Keep Big Fish With Angelfish?

If you want to keep bigger fish in the tank alongside Angelfish, the fish shouldn’t be predators of Angelfish. Otherwise, they will feed on your Angelfish. Therefore, you should not add fish that can prey on Angelfish to the tank.

You should only add compatible fish such as

  • Rainbow fish
  • Peaceful barbs
  • Large rasboras
  • Tetras
  • Medium-sized catfish
  • Corydoras
  • Gouramis

Water and Tank Conditions for Angelfish

The appropriate temperature for the water is 78°F to 84°F. The pH of the water should also be ideal for their existence. The water should not be too acidic and also not to be too basic. The perfect pH for the water is from 6.8 to 7.8.

Angelfish do not do well in hard water. So, the water should not be too hard as it can significantly affect their health.

The water should be slightly hard and should be around 30 and 80 (54 and 144 ppm). The water should be changed regularly, and you should ensure that it is adequately filtered. You should treat the water, especially if you are using tap water before adding it to the tank.

The tank should be as large as 55 gallons because Angelfish needs a lot of space to grow. They are also beautiful but slow swimmers, so they need space to practice their swimming ability.

The tank should also contain some decorations that will make the fish tank look like their natural habitat. You can also add leaves or objects to the surface of the water to provide shade for the fish.


Angelfish do just fine when they are alone in the tank but will also do well when they are with other Angelfish (preferably in pairs). Angelfish can also be happy to have different species of fish.

This introduction will work only if their existence together in the same tank is compatible. Angelfish can be very generous in accommodating other fish.

It is not advisable to keep smaller fish in the same tank as Angelfish prey on smaller fish. Also, it is not advisable to put bigger fish that prey on Angelfish in the same tank so as not to lose your Angelfish.
