2... Male and female... i knew i wanted to breed but didn't have the right fin match... so i got the female CT and also took home another vt female baby cause i liked her, and was setting up a sorority, and then i got her because she's a monster...
pretty sure... little white dot, only visible if you look really hard when he/she flares out her pec fins. If it is a male it's pretty amazing because it lived in a tank (about ten gallon size) with around 8 other bettas that all looked about the same and none were ripped up.
i have put a styrofoam cup 1/2 in there so i can watch for a bubblenest.
eggs spot best way to go as some female's will make a nest i think i've seen ever thing dealing with bettas one wired fish had 2 female turn to males at 5 mo. had female take care of nest like male had one female kill 3 males and when the mateing started and then she die same way put big male in with hoeing she wouldn't kill him .but i love them still, how old is this fish?
