I have another thread going in a different forum, but I think it's time to ask here. I bought a seemingly healthy Barbonias anthias one week ago. He was in a tank with two others, all seemed fine and swimming normally. When I put him in QT for the first three days, he would hide either behind the top of the heater or HOB upside down. I got him to move, but he has glued himself either to side or underneath a rock. He is not eating or swimming at all. If I stick my hand in the tank to move the rock, he goes into my hand and won't leave. Any ideas? Others have said it could be swim bladder issue.
