Got this guy about 2 weeks ago and has been in QT the entire time. Ive been feeding 2-3 times a day and he was eating like a pig. This is the second round of prazi. I go to feed him tonight and he isnt swimming normal. He swims with his body in a vertical motion and doesnt look well. Hes laying on the bottom of the tank moving his front fins and not his tail. He didnt accept any food this last feeding. Suggestions on what to do????
