Do a large water change. There could be problems in
the water causing this. Check ammonia, nitrite, and
nitrate.

My Yellow Tang recently has red marks on it's body towards its tail. The
obvious answer is that it has Ich or similar and has been rubbing itself
raw. However, it doesn't seem to really be itching itself or doing
anything odd, and I've been watching it for a few hours.

Is it just raw? Any comments? Ideas?
