#Reefsquad help identifying this.

My blue tang has completed 14 days in copper power 2.5ppm, now in observation. Just noticed a pale patch on the side 2 days ago. fish is otherwise eating. Any ideas what it is and what to do? Took some pics but he is very shy so can't seem to get a good shot....

Possible be the affects of using copper.

How long has this been going on? Has it been progressing slowly over time or more sudden?

Is there any redness?

Just saw it 3 days ago. Did not notice is prior. Doesn't look like its progressing. No redness, just the pale patch.
