Not to discourage you from ApistoDave, but I have heard the same thing over and over: people ask for a pair and are sent 2 of the same sex. This seems to happen quite frequently with him. Even after people saying that they ordered a pair and were sent the wrong thing, he sent the wrong thing AGAIN. He has some nice fish but I don't know if I would trust him. I think I remember there being a complaint about him on this forum even for the exact same reason as mentioned above. Just do some checking around on him.
