HI so I have a community tank with one male and three female Bettas and no they don't fight the tank is big enough and the male is calm... So recently he had a nest and bred with one of the females in the community tank. The corys destroyed the nest and the black tetras ate the eggs.... So I thought I would put him in his own tank with the other female she has breeding stripes and is eggy... So because the other tank is smaller and she is more flighty they are not in together but both displaying and courting I put her in for short amount of time..she destroyed thetnest Being flighty as she is .. the thing is he is not rebuilding a nest ?? How often can males breed ?? Oh and yes I have room for fry and will give to good homes .... Any advice ??
