Since he has only been in my tank for a few hours, is it more likely that he got it at the store, or can it be contracted that quick? all of my other guys look fine. I am getting a 5 gallon tub with a heater and power head set up as a temp sort of hospital tank. It doesn't look like any of my other fish have it, I hope not anyway. I have a tang in a 29 gallon because that is the size tank I have and I wanted a tang. If you don't agree with what someone is doing, it would probably be best to just tell them that in a kind way and the reason why. Asking me why I have a tang in a 29 gallon just sounds snippy and isn't very helpful, which is the point of this board. I'm not trying to start any sort of hostile back and forth going here. I have seen you post quite a few other times where you were genuinely helpful. Dunno, maybe I just caught you at a bad moment. I do appreciate your reply.
