Blue Hippo Tangs

[jsolomon]

Does anyone else out there have a blue hippo tang? I purchased a pair of hippos about 3 months ago from my LFS. Ever since then they have done nothing but give me a constant headache. These fish seem like they are prone to every disease out there. They came down with ich about a week after I got them. I treated them and they started doing good again, until they starting coming down with HLLE. I feed these fish 2 times a day with food soaked in Zoe and Zoecon, and also feed broccoli every other day soaked in Zoe and Zoecon. The HLLE actually started looking a little better, and now both of them have come down with ich again. Has anyone else experienced this many problems with this type of fish? This makes me want to just change my entire tank over to perculas. I have never once had a problem with any of my perculas, I have 3 of them.
All of my water parameters test perfect.
92 Gallon
600 GPH Filter
100lbs decorator rock (not live).
About 2 lbs of live rock.
77 degrees
S.G. 1.020

what about a UV sterilzer? You think this will help to preven this type of disease, and if so, what brand and how many watt for a 92gallon tank with a 600 gph filter?
