i have these ans have had for a while the femalesless than 2 inches, at least the ones i bought the males smaller but the females are prone to balloon out when bearing for a while, just get really big, not pine coneing, just really big and then die mine don't seem to have very many fry maybe 2-10 at the most and i feed good..
i love them but i think they would be happier without the males..
