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.
Well, if you love your Betta fish, then it should live by itself. But if you add another Betta to your current Betta fish's tank, then they will start a fight because Betta Fish are Siamese fighting fish and if one Betta is in contact of another Betta, the possible reason would be a fight between them two.
The betta fish will see the mirror and then will be curious about it, because the mirror reflects the betta fish and they might think that it is another fish, so the fish will act differently.
Betta fish get in fights with fish with colorful fins and bodies. If your betta gets in a fight while your away,the weaker fish may die. But if you see your betta fight with another fish you should try to split the two fish apart [or all the fish that are fighting].
Yes. Betta Fish do change their coloer every now and then. Or if you have a male, he will change his coloer if hes chaseing a female Betta Fish. Or if he sees another male Betta Fish.
NOOOOOoooooo. The oscar would eat the betta fish almost instantly.
A betta fish? You can't or they will kill the tank partner
Most fish get along well. However, do NOT mix betta fish with other fish. Not even another betta. You have to have a permit to have to betta fish in the same tank with eachother. Betta fish are only mixed to mate. Bettas are not born in the egg. They come out as a very small fish. After the betta babies have come out, all of the fish are seperated. Even the parents, if the betta babies are left in the tank with the others the betta parents are very likely to eat the others.
Bettas are dumb as rocks. If you put another betta, any other anabantid like a gourami, or any long-finned fish in with a betta, the betta will fight it because he will think it's another betta. If you put a short-finned fish in with your betta, they'll live together peacefully.
When the fish is swimming around by the top of the water, or where you ushually feed them.
Fish are not stupid. There is no chance that a Betta splendens would mistake a guppy for another Betta.
no because the male and femalebetas are the type of fish that live alone. therefor since their opposite sex then there is a chance of them being OK with each other, so if there is another fish with them then they will attack it and eventually killing each other.
other Betta fish and the bigger fish.
