Betta fish likely live alone but if you put them together in a tank, do betta fish eat each other? In their natural habitat, which is a paddies field, male bettas like to fight to protect their territory. If bettas are killing each other, it does not refer to cannibalism.

Instead, male bettas possibly bite their rivals to keep them far away from their territory. Thus, make sure you use a very big tank to keep several betta fish, especially if there is more than one male betta fish. The standard size to keep a group of male bettas is 40 gallons.

This size will ensure the mild male bettas stay far from the dominant ones. However, if you only have a small tank, you need to avoid keeping two male bettas together in one tank. Hence, do betta fish eat other fish from the same species? It may happen due to territory reasons. 

Do Betta Fish Eat Their Eggs?

Many fishes like to break their eggs. However, betta fishes are good parents. In the tank, bettas likely put their eggs in the corner with minimum flows. Male bettas oversee the eggs before hatching. Even male bettas protect their babies until they are safe enough to scavenge from the nest.

Bettas may eat their eggs when they are bad like the ones affected by the fungus, infertile, or dead. Male bettas will eat these undeveloped eggs to save the good ones. It is because fungal threads can affect other good eggs when they have infected one.

Bettas rarely eat other fish because most fish are too big so they cannot fit the bettas’ mouth. Even many smaller fishes can swim faster in the tank than betta fish so bettas are unlikely to eat them. If it possibly happens, it is because the fish’s size is too small and they swim slowly in the tank.

However, it does not mean that your betta should always live alone in the tank. There are several fish and water creatures that get along well with betta fish. Not only because they have bigger sizes but also due to different characteristics that allow shifting active time.
