Hey everyone, for the past week or so my domino damsel was a very happy fish, then after a week he stopped eating. Last night about six i saw him swimming near the bottom brushing aginst the live rocks and just looking pitaful. I remembered the day before that he wasnt eating at all, either. I bought the fish from Petco, was he possibly an unhealthy fish? Now, i can't find him! I think he was burried while trying to find him in the tank. All levels were at 0 and the tank was perfect, the only thing i could think of is the temp being a little high, holding constant at 80 degrees. any help is greatly appreciated!

Thanks!
