Female Betta need to be in groups of four or more. They are aggressive and if you only have two, they will likely kill each other. If you have enough of them, the aggression is spread out and they can be relatively healthy and happy.
It is only a myth that female bettas will not fight each other - they are very territorial and can be as aggressive as the males. One will try to dominate the other. Try introducing them after a water change, and try to put them in the tank as closely to the same time as possible, so they don't become too territorial. It is not recommended to put them in a group of three as two may team up and pick on the third fish.
If you notice them fighting, just create a water current manually, as this will discourage the behavior, and after two-three days they should get along fine.
Provide lots of hiding spots for them! This will allow them to hide and rest when they need to.
Never mix male and female Betta outside of breeding a pair. Also, never tank multiple males together because they will kill each other.
Male Bettas can not be kept with any other members of the Betta family. They can be kept with other species quite safely but will not tollerate another Betta (male or female) in their vicinity. Female Bettas can be kept together OK.
male
Only female Bettas can be kept together. That too will only work if they are given reasonably roomy conditions and plenty of cover (plants) and hidey holes. Male betta fish can/ will fight to death if there is another male fish in the tank, a male will sometimes eat a female so your best bet is to have a single betta or a female and a female.
She breeds with a male Betta Fish.
yes
No.
Your betta fish is a female if she has smaller fins than an average male.
Yes they will.
the male betta fish makes the nest.
No. Betta fish will attack each other no matter the sex.
No because if a male betta is not atracked to the female they will try to reserve there territory
Do you mean female and male? If so, then the female betta fish is smaller and less elaborate than the male.
