It would be a pleasant surprise to have an elusive male as it seems they are fairly rare in the hobby. I guess time will tellIts probably still to young to tell but to me looks like it could be male. I dont think it's mature yet though. It's funny until my dels hit 8-9 inches I thought they were both female. Then all of a sudden tthe fin widened and got real bulgy around the base and I would catch them cupping the fin. So it can change overnight.
