Yellow Tang doing the Macarena

[dalley]

I've done some research on this board for similar problems regarding this but I still feel the need to tell my own version of the story. I have a 90 gallon reef with a YT, Blue Tang, Flame Angel, cleaner shrimp, snails, hermits, etc ... I've had the YT about a year now (he's about 4''), and never had any problems. Over the past few days, I've noticed he's been swimming around very strange, almost like he is having a siezure. The thing is, I do not notice any visable markings on his body to suggest any disease and he IS still eating. The tank has been running for almost 2 years, great water quality, etc ... All of the other livestock are doing well. Is it possible he could be stressed, coming down with ICH or anything else? Thanks for your help...

I guess "jerky movements" would be the best way to describe it. There is plenty of swimming room for him, I have about 75 lbs. of LR in the tank. Nitrates are in check, around 8, sg has always been 1.022, and my PH is 8.0. I wouldnt say there is any color loss at all. I feed Formula 1 flakes, Seaweed selects, Spirulina wafers & the occasional frozen brine. He pretty much will eat anything. The only thing that sucks is that I dont have a QT set up in case it is something that could be contageous....
