Can Angelfish Live With Betta

Angelfish are peaceful fishes with a lot of attractive qualities. They belong to the Cichlidae family originating from the Amazon basin, rivers in the Guiana shield, and the Orinoco basin. They are compatible with several species of fishes but can be aggressive towards other cichlids.

Angelfish and Betta can live comfortably and peacefully in the same tank. Although they can live peacefully, it is always safe if you have a spare tank prepared and you can move your Betta into it whenever something happens.

How to Reduce the Chance of Aggression between These Fishes

Angelfish are peaceful fishes with short days of aggression. They show little signs of territorialism and mostly show their aggression to fellow cichlids, especially during spawning. Unlike the angelfish, bettas are highly territorial, and the males display high-level aggression.

These two distinctly different personalities can compromise their compatibility. Although they can live together without a problem, Bettas can lose their cool, so you have to prepare an extra tank.

Aside from preparing for the worst, you can also reduce their chance of aggression. By doing this, you might not need the extra tank. Here are some ways to reduce aggression.

  • Get a big tank: Bettas like to exercise territorial behaviors and will display it at every chance they get. Getting a big tank will give the Betta enough space to exercise its territorial behavior and allow the angelfish to stay away from it.
  • Add plants and decorations: Plants and decorations are also good as they will allow the angelfish to run and hide in the days of aggression.
  • Keep female bettas: Female bettas are not as aggressive as male bettas, but they can be nippy at times. Female bettas will live peacefully with angelfish, but they will repay in kind when they start to nip at the angelfish’s fin.
  • Add angelfish at the early stage: Adding the angelfish when they are young will allow the fishes to get used to the lifestyle. Besides, angelfish are always peaceful at their early stage. They grow to become aggressive, especially during spawning.
  • Keep an eye on them: Ensure you keep an eye on them to monitor their behavior. It will let you keep track of their aggression.

Water Conditions for your Angelfish and Betta

The Betta and angelfish have similar water requirements. They can thrive in the same water conditions. They also have requirements that are not similar, so you have to choose to know the critical water conditions that are suitable for both parties. These are some of the water conditions that are suitable for both species;

  • pH: The pH is a measure of acidity or alkalinity of the water. The pH ranges from 0 to 14, which measure the highest acidic value to be 0, the neutral value 7, and the highest alkaline value as 14. Angelfish are hardy fish, so they can thrive in pH that exceeds their pH range. Bettas, on the other hand, will thrive in slightly acidic water. They will also thrive in neutral and slightly alkaline waters. Angelfish do not mind this pH range and will gladly stay in the water. The pH value to keep both species in should range from 6.0 to 7.5.
  • Temperature: Angelfish and bettas have similar temperature requirements. While the angelfish has a wide temperature range, bettas have a closer temperature range. The ideal average temperature should be about 78°F. The temperature can also fall between the range of 760 to 800F, which is suitable for Betta and angelfish. The temperature range for angelfish is between 740F to 840F, making it adapt to Betta’s temperature requirement.
  • Hardness: The water’s hardness is also a necessary factor to consider when keeping angelfish and Betta together. Angelfish are hardy fish, which makes them thrive in extreme conditions, including hard and soft waters. But bettas are not very hardy, so you must be careful about the water’s hardness. Bettas will thrive in slightly hard water or preferable soft water. This hardness value is also suitable for the angelfish.

Tank Conditions for Bettas and Angelfish

There is no specific tank condition for your Betta and angelfish. You only have to check out their tank requirements and derive the requirement that will be suitable for both fishes. You can do this by picking values that suit both species.

Bettas do not need a very large tank to thrive. They can do well in tanks as large as 30 to 40 gallons depending on the species you are dealing with. Unlike Bettas, angelfish requires very large tanks to thrive. Angelfish require tanks as large as 55 gallons to enjoy their stay in the tank due to their large size.

Bettas do not have any problem with large tanks so, they will do well in the 55-gallon tank. Putting the fishes in a large tank will give them much space to claim territories, reducing the level of aggression that crops up in the tank.

It is necessary to equip the tank with substrates and decorations. The decorations will serve as a hiding space for the fish when the other party becomes aggressive or territorial.

Driftwoods, broadleaf plants, and rocks are good decorations for the tank. Substrates are also very essential because angelfish like to forage for food at the bottom of the tank. The substrate will also allow the burrowing of the fish. Smooth gravel and medium grade substrate are good substrates for both fishes.

You can also add other aquatic plants to the tank to beautify it. These plants can also serve as sources of food for angelfish because they are omnivores and tend to feed on plants. Small aquatic animals are also suitable tank additions as they serve as food and companion to the fishes.


Angelfish and bettas are suitable tankmates with a lot of similar water and tank requirements. These two fishes can live peacefully under the same conditions. Do not forget to prepare a spare tank in case something happens. You can also reduce the aggression between both species if you follow simple procedures to save yourself from the stress of getting another tank.
