help with tang

[jntmcduffie]

I just go a new yellow tang yesterday. today it is looking kinda pale and looks like blood in it top fin and stomach area. dose anyone have any ideas?

were you looking at it right after the lights came on? When they "sleep" they bleach out a little bit. The white stripe on the side becomes visible too. After a few minutes of the lights coming on it will get its color back. Is he breathing fast or slow swimming, is he eating?
I dont understand why this got flagged?
