male fish are territorial he is claiming his territory
yes they can.
NO they will attack each other
no you can not put a female and male fighting fish in the same tank because they will just kill each other
No. The females will kill each other.
No. Betta fish will attack each other no matter the sex.
Fighting Fish do eat each other so, yes
no because they will end up killing each other
beta fish are very territorial if there is plenty of room for both of them in a tank they will just leave each other alone and another reason is that they haven't had to compete for food
have them neutered
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!
Sometimes they like each other and sometimes they don't.If a male fish and a girl fish of the same breed live in the tank and spend 80 percent of there time around each other than they must like each other
It is almost impossible to tell the difference. Sorry!
