I bought a group of Satanoperca Daemon and they were doing fine in my 29 gallon for a couple weeks but I felt as if they should be in my 110 gallon. So I moved them and they started acting weird... Their fins never opened or flared and they only make repetitive small movements as if they are having trouble swimming. So I did a good water change in my 29 and I moved them back but now they are staying up in the corner acting the same way. They are eating but they don't look too good. What should I do? Feedback is greatly appreciated, thanks.
