Thanks for all the help guys. I did basically a 100% water change and started over with some of my main tank water. I have the emperor in there now (which by the way his name is Bandit) in the QT and am dosing the erythromycin.
What doesn't make any sense to me is I was using erythromycin while I was dosing copper at the same time. I suppose my ammonia readings just got so high in the water that Bandit came down with cloudy eye even though I had erythromycin in the water? Bah it's all confusing to me, I don't know why I can't just have an aquarium ever like some people and not have any ick or health problems with my fish :P
Any how just so this doesn't happen again once these guys are all 100% again (and hopefully I don't lose Bandit or any of my fish for that matter) I am not only going to make a much better effort for weekly water changes and maintenance, but I am going to get a cycled QT up and have it all the time just so if this ever happens again.
Oh and how long with the erythromycin take to work? His eye looks HORRIBLE! It's huge, I hope it's going to work.
Stingrays are the best!
