My molly is upside down. I don’t know if he has ammonia poisoning or swim bladder. It started out as clamped fins and he was in a u shape at the bottom of the tank for a day. Then he started swimming better and around the tank. Two days later he started swimming vertical and is now upside down. I have him in an isolation tank and am continuing to do water changes to lower the ammonia, but he seems to be getting worse. (Ammonia started at 8 and is now around 3 ppm)
