they are supposed too.
No. You need one of each.
i dont no why should i? Unless they are really well trained, you have no chance. Try talking to someone at a pet shop or a fish expert.
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.
Betta fish of the opposite sex will not always kill each other. It is actually an uncommon occurrence.
I have never seen any Betta fish's go crazy, but, it is possible.
No. Betta fish will attack each other no matter the sex.
yes
No, they are fighting fish. They will kill each other no matter what sex they are.
Betta fish can communicate through colors and body language. A betta fish can use fins to show it is ready to breed, and can change its skin to have black or dark vertical bars to show it is ready to breed. A male can communicate to other males to stay away by flaring it's fins and fanning it's gills at it's intruder.
They may just not have been doing it right, especially if they haven't been breed before. Practice practice practice.
NO they will attack each other
No, unless their lesbian.
