Hey guys I picked up a clownfish for my other friend who has not had a partner for weeks...(he died during QT) and at first it got what seemed to be gill deterioration or around that area so I exchanged him for the only healthy looking clown in the tank. Now he still looks healthy it's just he hangs out near the bottom swimming slow opening his mouth and closing it very slowwww...not accepting much food. What are the possibilities?
