Ray,
At the only saltwater store in Indiana, Pa I saw the most horrific thing today. They had a Clown Tang, and a Convict Tang together in a 10 gal tank. I'm not one to call the tang police but I couldn't believe my eyes. The Clown Tang looked really healthy and the Convict was starving to death while trying to eat anything it could but with nothing in the tank. They both were desperately trying to eat constantly nipping at anything for food. Im guessing that they just had got them in and wont last long.
