Chromis like cleaner shrimp?
 

Just curious, but several times in the last month I've seen a chromis or two of mine clinging running close by my tang and pecking it's side, then returning back to it's crew of other chromis. It never looks malicious, but I'm wondering if it's trying to clean some of the few ich spots off or what? I've seen the chromis do the same to a few other fish, but was just wondering if anyone else has seen this behavior?

Yes, I have. Sometimes yellowtail damsels do it when they are bored...lol

My Green Chromis do this with a few of my fish they don't seem to mind at all.
