Mainly for territorial and mating purposes. Bettas are very territorial and will attack any fish with bright colors and large fins. Especially other Bettas. Bettas flare when threatened by opening out their fins and extending a 'beard' from under their gills.
yes
anyother fish, they only fight with each other
Female beta fish are better in this way, they don't fight, allowing you to put them in a tank with each other as well other fish!
Betta Fish do fight that is why they need to be put in separate bowls or else they will kill each other.
You don't. Those fish are bred and born to fight each other. Keep them in seperate tanks. Sorry :(
The Betta fish runs away when facing another Betta because its the first time facing another one. Or its just scared of it and doesn't want to fight since its not use to it and its a FIGHTING fish. But once its use to it the other Betta they well start getting up close to each other face to face and start ripping out each others fins out and basically trying to kill each other chasing each other around.
No. Betta fish will attack each other no matter the sex.
If you refer to a Siamese fighting fish (betta), they are territorial toward each other. They will most likely fight each other if there are more than just one in the same tank. It must be avoided.
They may seem to become friends but they are alway foe and will fight at any given moment. They do constantly size each other up and that's were you will see them look at each other like they are going to fight.
They are instinctively fighting over territory and breeding rights, only one male will dominate.
Separate them in the tank by placing a glass partition between them. It is the males that fight.
Betta fish of the opposite sex will not always kill each other. It is actually an uncommon occurrence.
