I have a Juvenille Blue Hippo Tang about 4" but it has ick, it comes and goes, when it goes the tang's blue is very royal. He's an aggressive eater. I've been feeding him Formula 1, Seaweed, mysis shrimp all soaked in garlic, and my cleaner shrimp and bloodfire are constantly cleaning him, i'm even using Kick ICK but for some reason he's stressed in my tank and the ick keeps coming back, and he's infected my other fish, this sounds crazy but if anyone has a quarintine tank and can rid the ick from the tang and would like to trade me something for it like Ricordeas, ZOOS, cleaner shrimp, live rock, I paid $45 bucks for him, i'm not expecting that much in trade cause of the ick but something reasonable. Crazy I know but if someone can keep him healthy then i'd rather that.
