Well expert.. you would know then that getting them past sexual maturity doesnt necessarily make them immune to parasites. its the fishes growth and the body matuing and building the immune system that give the fish a fighting chance. and herasy c'mon that doesnt even make sense. thats a biblical term. please dude i would think you of all people would know that. so when i said past two inches i wasnt talking about sexual maturaty, as that has no significance but actuallay the fish itself growing to the size of three to four inches, that make it more able to fight off sickness.. whatta a pompous jerk
