Ace isn't looking so spiffy today. He's really lethargic, and he barely ate any food, when usually he's attacking himself to get at it. It's really worrying me. He looks the same as always, just slow. The water temp is fine. He's hiding in his pagoda, and it took me about 5 minutes to get him to come out. I don't see any fungal infections, and his fins look just like they always have. I don't see any labored breathing, but his fins do look a little clamped. Any ideas on what's wrong with my baby?
