Hello! I have recently upgraded to a 55 gallon, and noticed today that 3 of my fish swim a few degrees off. I have a blackmoor, a ryukin, a baby lionhead and a comet. The blackmoor, ryukin and the comet are the ones having trouble. It's probably just minor constipation, as my smallest fish, who gets the least food, is just fine. Any ideas on whats going on would be appreciated!
