I've had this amazing looking GT for over a year now, I treated him a couple months back for what I thought was dropsy. It seemed to work very well, when I put him back into his original tank he was fiesty and thriving and ready to gorge himself. The past week he hasn't met me in front of tank and eagerily taken pellets, now today he started hiding a touch and when he came out he swimming with a lot of weird body motion. Still has his dorsal standing up but, didn't go after any food and putting his body into swimming. Any ideas?? Thx in advance.... Water conditions are all excellent, well established and filtered 55Gallon grow out, occupants (2 others) have been the same for the last 6 months, and he dominates the tank...
