My apologies, this is posted in a build thread, but I thought I might get a better response if I posted it separately.

My Cole Tang, while appearing otherwise healthy and eating like a pig, has started to lose color on his face. It doesn't really look line "Hole-in-the Head", it just looks like he's scraping the color off of his face. He does swim very quickly in & out and around the rocks and I suppose he could be crashing into them, but I really don't know what's going on. Does anyone have any ideas?

Thanks in advance for the advice.
