After my aunt gave me my fish, Ravi(still don't know if he is a Super delta or HM) about two Saturdays ago, my cousin (asked me two days) didn't want his bettas anymore and I couldn't say no. .___. So I have three female bettas, and I want to try make a sorority with them and probably 3 or 4 more females in a 10 gallon. BUT... one of the 'female' looks like a male. .___. Actually, not just looks but I have a feeling that s/he is a he. Probably because of how aggressive s/he is, so kind of a lose-lose for me? I have a spare tanks, but not heaters. I can't tell apart male plakat and regular females. And I can't trust petco/smart labels. As all the fishes he got were labeled veiltail, but all of them are crowntail.
So can you guys help me identify this little fish?
