I have about 25 female bettas & 6 males. I'm only a beginner at this so haven't spent a lot of money on actual fish so if I get it wrong I'm not losing a lot of money although I've spent about $800 already. I'm not sure if I'll breed for the hell of it because I don't know what I'd do with all the fish I'd end up with but my husband Ken seems to be heading in that direction.
