One of my fishies lost his buoyancy completely for awhile. The poor thing had to pump his pectoral fins constantly to keep from sinking. He couldn't even rest at night. His stomach also looked deflated. I figured he was a goner. He looked so thin that I was sure the exhaustion would do him in.
But the little champion's still here! He's also been able to inflate his swimbladder somewhat. The hind end of his abdomen is "inflated." He still has to work harder than the others to maintain position, but he's a lot better than he was.
He never stopped eating the whole time. But because he was at the bottom of the totem pole to begin with, I'm sure being chased around doesn't help him. I tried separating him to nurse him back to health, at least make sure he was getting plenty to eat. But being away from his tankmates bothered him more than the chasing.
Does anyone have any thoughts?
