blue tang

i just got a blue hippo tang and he has been hiding since new years eve, anybody know whats happening? he wont eat nori or anything. i have heard that it takes them a while and its normal but i think it has been going on too long.

i have a 55 gallon saltwater, and i have currently a clown and a BTA, it has 90 lbs of live rock and 800gph filtration with a 7 gallon refugium. i was planning on temporarily getting a hippo blue tang and a yellow tang. do you know what order i should add them to the tank?

Is it normal for Blue Tang's to have a faded look on the black part? We just got our first Blue Tang & when I got it home & under our tank light I noticed it. It has no white spots so I don't think it ick. It just looks faded. Any ideas?

We bought a Blue Tang today & when I got it home & under our tank light I noticed part of his black part in its back looks lighter almost faded. First time with a Blue Tang & don't know if this is normal or a sign it's sick. I have it in quanitine to be safe. I see no white spots so I don't...
