Water parameters are fine. He's been like this for a while now. Went from a 55 to a 125 about a week ago, but he looked the same even back then. He eats bloodworms and sinking pellets. Definitely eating normally. Right now, he's in there with 3 golden labs, a chipokae, 4 convicts, a baby frontosa, black spotted eel, and a cobalt blue zebra.
