My beautiful red CT Jericho has had no problems for the past 2 or 3 months since I got him. He is in a 5 gal tank and I do water changes every week or so. This morning I looked at him and he is just sitting on top of the water in the corner of the tank. He wont move and he wont eat! What could it be!?
Sounds kind of like swim bladder, make sure it doesn't have missing scales lumps or white bumps. It shouldn't have have any tears or rips (but the funs may have separations since it's a crowntail). Research swim bladder disorder. Hope he's ok!
