We all know how difficult it is to identify the sex of these fish, so please post a picture in here and we'll try to help you (or at least give an educated guess!).
Chanett - agreed with the head as being a male. Not typical female head.
At first glance I thought the fish was a female too... just because her body shape didn't have a taped body like a male and the belly was very round, and the hair on the pectoral (front side fin) was not the hairy compare to most males that I have saw.
Thanks all for your opinion.. Anyone else...
P.s. I just put he/she into a tank with a mated pair ... going to see what happen and I just did a big water change too...
