Male betta fish tend to be very aggressive. They are best alone unless theres a special type of specie they can get along with. They like to have personal space. And as using fighter fish you probably refer to Siamese fighting fish which is betta fish
Fighter fishes do not like other fighter fishes and attacks them. So you should try keeping them in different tanks/bowls immediately! Fighter fishes will fight each other to death so you better be careful with them.
If by feeder fish you mean the common goldfish it could be because of stress. And if you have a heater goldfish are cold water so that may cause aggresion
how to take care of egg when fighter fish male die
no you can not put a female and male fighting fish in the same tank because they will just kill each other
Why wont my boy fighter fish blow his bubbls
yes once it has a male or a female with it
Betta splendens (Siamese Fighters) usually find a quiet corner to hang out in. They are not active fish.
None are recommended if the Betta is a male.
the male fish will protect the female if there are other fish. just make sure when your guppies have hatched, they are safe in a other tank.
If you have a beta fish, you CAN put it in a tank with another fish IF that fish does NOT have flowing fins or tails, such as a goldfish OR DO NOT put it with a fish that's not social and that attacks other fish so you CAN put a beta fish with another fish if it's not very pretty so it doesn't look like a beta and if the other fish isn't a fighter.
Any.
have you ever thought that your fish were not compatible? Some fish such as beta fighter fish are very domianat over territory and can not be in the same tank as another fighter fish. I believe tha your fish may have fought leading to the rips in their tails.
Male beta fish are very territorial. Two male beta fish cannot live in the same tank or they will fight. Male betas make bubble nests to mark their territory.
If two male Betta (Siamese fighting fish) meet, no matter the volume of the tank, they will fight. Some breeders will put opaque sheet partitions in the tank to keep the male fish out of sight from each other. Females will happily keep together in the same tank.
