I have a 90 gallon reef tank. I had red mushrooms takeover and so I have decided to redo the tank. I have a Pacific Blue Tang and a Clark's Clown that have been with me for about 3 years. I hate to get rid of them, but they kill everything and anything I put in with them. Is there anything they won't kill? Otherwise I will trade them at the LFS when the time comes. They are gorgeous fish and I hate to get rid of them.
