Yet Another Issue

[FishLover66]

Ok, this is so very frustrating. I've been treating my tank for a major ick problem (apparently we have a very resistant strain) and thought I was in the clear this morning, since I didn't see any Ick for an entire day (still treating with heat and Ich Attack, although I lowered the temp from 89/90 to 86/88). I noticed yesterday that one of my neons seemed to be having a hard time swimming straight. His head drifts down with his tail in the air. Today, I noticed that he couldn't 'catch' the flake food as it drifted down and looked as though he was drunk. He keeps floating up. I assume he has swim bladder disease. Has anyone dealt with this issue before,and if so, any recommendations on how to treat it, if it is even treatable.

Keep in mind I'm still treating my tank for ick and will likely still be treating it for another week, since I found yet another white spot on one of the neons this afternoon.
