Red Marks on Yellow Tang

[pegboy]

This morning my Yellow tang had large red marks down both sides and on his head. Otherwise he is looking/swimming fine. Is this some disease, is something attacking him, or did he just scratch himself on the rock? With him are:
1 sally lightfoot Crab
A bunch of blue leg hermits and snails
coral beauty
scooter blenny
chalk bass
Percula Clown
Condi Anemone
Bubble Tip Anemone
I have had the tank for almost a year and these guys have all been together for 2 or 3 months.

It is uusually an internal bacterial infection very common with yellow tangs. What are your water readings?

I agree with jimi. If you don't have a UV sterilizer, get one. Regards, and:
