thanks and yeah its a male if you "lightly" press on the abdomen of a fish the male will squirt a clear substance from vent this is a sure way to sex and I sex all my fish he's just kokless I dont know if its genetics or the fact his entire life was spent in about a 1 gallon tank space with not even enough room for him to turn around not to mention lack of feeding, I hope in my care and with some head booster he will get one
