I was wondering if anyone could help me sex my leopard sailfin pleco? At the end of the school year I will be moving and I will be putting this fish with what we were told is a male of the same spieces. I want to know if there would be any problems putting them in the same thank as the tank is a 55-75 gal and I only have a 30 and my pleco will be close to out growning my tank by then.
