My Powder Blue shows his stress pretty well. He gets dark vertical stripes and goes crazy if something pisses him off. Anyway, He may be getting to large for the 90 gal
I have him in, but he was in a 75 for 2 years and I just got the larger tank. I know that if he grows to adult size the 90 will be to small. Honestly he doesn't seem stressed.
What I was hoping to hear is that the skunk cleaner shrimp was somehow causing damage to his skin, but I guess nobody has experienced that. It seems that you all believe he has ick. It does not look like marine velvet. If I could somehow use the old 75 as a qt I would pull out all the fish for 8 weeks, but that's probably not going to happen because of space.
Because this has been going on for weeks, I am a little worried about all the fish. Has anybody used Kent MArine's product RxP? I used it before it the QT years ago, but am wondering if anyone used it around corals. It specifically says not to use it with an urchin which I will have to figure out a way to get out.
After keeping freshwater fish since childhood and this reef tank for three years now, I would use copper or hypo sal, but am VERY reluctant at putting this large fish in a 20 gal
tank. That stress alone would probably kill him.
