Can Angelfish Live With Bettas: Things You Should Do to Make It Work

Yes, bettas and angelfish can potentially live together in a tank, but it’s important to remember that they are both fish and should be treated as such. Bettas are more carnivores than herbivores, meaning that they eat meat, so if you have an angelfish in your tank, it’s essential to ensure that the angelfish is getting enough protein.

However, aggression may occur if the aquarium becomes overcrowded or if one fish feels threatened by the other. Additionally, angelfish may nibble on the betta if they become bored or unhappy. If you’re concerned about compatibility, it’s best to start with a smaller fish and add the angelfish over time.

How Can Betta Fish and Angelfish Live Together?

Spacious Aquarium

For the most part, betta fish and angelfish can coexist peacefully in an aquarium if given plenty of space to move around. However, aggression may occur if one fish feels threatened by the other. The tank size is also essential when it comes to can angelfish and bettas living together. For example, a tank that is too small may cause aggression, while a tank that is too large may create overcrowding.


Another essential factor to consider is the age of the fish. The age of the fish also affects compatibility. For example, young betta fish are more likely to be aggressive than older fish, and adult angelfish may not be as tolerant of other species. If you’re unsure whether your tank is big enough for both species, start with a smaller fish and add the angelfish over time. In addition, angelfish should be kept separate from other smaller fish, as they may nibble on them.

Fin Length

Some angelfish have more extended fins than others, which may give them an advantage regarding territoriality. If you plan on keeping your betta and angelfish together, make sure their fins are of similar length so they will not feel intimidated by each other. In addition, it is also essential to keep an eye on the water temperature, as warmer temperatures will encourage territoriality and aggression.

Can Angelfish and Bettas Become Aggressive If Kept Together?

If you consider adding an angelfish to your pet betta fish tank, it is best to do so if the aquarium already has other compatible fish. Otherwise, aggression may occur. Additionally, ensure the tank is of sufficient size and that the age and fin length of your new additions are compatible with those in the existing aquarium.

How to Reduce the Chances of Angelfish and Bettas Aggression

When it comes to can angelfish and bettas living together in an aquarium, you can do a few things to help reduce the chances of aggression. One important thing is ensuring each fish has enough space to move around. If one fish feels threatened, it may become aggressive towards its tankmates. Another critical factor is introducing your new additions gradually into the existing aquarium, so there is no fear or intimidation.

Observing the Two Species

Of course, the best way to avoid any potential aggression issues is to keep an eye on your aquarium and watch for signs of conflict. If you see either fish showing aggressive behavior towards their tankmates, take appropriate action. This may include separating the fish and moving them to a separate tank. In addition, you can try adding a fish that is considered “friendly” towards both betta and angelfish. An excellent option for this kind of situation would be the clown loach, which is known as a peaceful community fish that does not get territorial when it comes to other creatures in its aquarium.

Backup Aquarium

If you have to deal with aggression between can angelfish and bettas in your aquarium, it is always a good idea to have a spare tank ready just in case. This way, you can temporarily move one of the fish out of the mix without having to re-home them. In addition, it may also be advisable to disconnect one betta from the can angelfish’s territory so that they have both of their aquariums and feel secure.

Suitable Habitat for Both Fish

Ultimately, the best way to avoid any potential problems is to keep all of your fish in tanks that are designed specifically for them. This means having at least 55 gallons or larger per species and ensuring there is plenty of space for each fish to move around. When introducing new additions, try doing so gradually and ensure they have time to get used to their new surroundings before things start getting out of hand. And finally, always have a backup plan in case things don’t go as planned – having a spare tank on hand is always an excellent idea.

Ideal Habitat for Angelfish and Bettas

The perfect habitat for can angelfish and bettas in an aquarium has lots of places to hide, chunky rocks to hide behind, and plenty of water movement. This will give the fish plenty of space to swim without feeling crowded and provide them with some fun distractions from potential aggression. You could try adding various plants and decorate the tank with soft plastic ornaments if you want to make it look a little more like its natural environment.

pH and Temperature

Angelfish and bettas are aquatic fish, so keeping their water chemistry and temperature in check is essential. In particular, angels need a pH range of 6.8-7.8, while bettas prefer slightly more acidic water with a pH of 6.5- 8. Both species should stay at 75 degrees Fahrenheit or 23.9 degrees Celsius at all times, and they will do best if there is plenty of oxygen and good water movement.

Lifespan & Size

The lifespan of an angelfish and bettas in captivity is typically six to eight years, although some individuals may live longer. Bettas are larger than angels and can get up to five inches long, while the angelfish averages just over an inch. As with all fish, monitor your pets regularly and water them properly if they show signs of stress or sickness.
