how do you know its a male? I'm not very familier with the species... I've had him for about a year or 2 now, and he was the replacement I picked out, after my tiger clown pleco died .... but this guy is a bit bigger and slightly less shy.....
the females lack the large bristles on the top of the head that yours has, hence its a male. just don't get another male. get a couple of females and theyll breed like crazy
yeah, I have young teenage girl BN pleco myself in my 10G. Just likes chillin' in her little cave, and kicking my betta out when he pokes his nosy head in there....
