I'm having trouble with my Panther Grouper. His white color is turned gray. He wont eat and lays on his side. Swims very little. Seems to be breathing hard. I have been feeding fresh shrimp. Just offered fresh Oyster and Squid. It landed on top of him and he still just lays propped up against the glass. Sometimes he is laying on his side. He is about 4" long. Nothing added recently. Water is near perfect. He has been in the tank since it was new around first week of January, All other fish are fine. Any Ideas ?
