It depends on the species of fish. Some will, some won't.
cause they are hungry.
its kinda rare to see a beta eat a whole fish, usually they injure and bite other fishes. but its a high possibility that a beta could eat another fish if its really really hungry, due to its instincs, but usually the fish cant be bigger than the betta itself.
Fish may bite other fish as a form of competition for territory or resources, establishing hierarchy within the group, or in defense against perceived threats. These behaviors can vary depending on the species of fish and their social structure.
No, they can live alone or with other female bettas. They might bite each other but won't kill.
becuse thay bite other fish
not most swordfish get along with other fish
They want to play with each other or they are bored and hungry. The third reason is bullying, leave the fish that bully's in a seprate tank for a while until it stops.
Because they are hungry.
They are allways hungry dont look at me im a 5 grader
Yes, both male and female betta fish bite. It shouldn't hurt you because they're too small to do any damage to you
When a fish dies other fish eat it because it might be hungry or it depends on what kind of fish you have that will eat the dead fish.like me when I have a dead fish my Osacar fish eats the fish because it a type of fish that eats other fishes.hope it helps. Bye
