Recently Shy Damsel

[l'eau IQ]

I have an "established" tank (1+ years) with a coral beauty, yellow tail damsel and maroon clown. The damsel was my first addition with the cb being the last around 8 months ago. They damsel and cb have always been active until recently. A couple of days ago I noticed the damsel would hide in the back and not even come out for feedings. As far as I can tell it hasn't eaten either flake food or frozen mysis since then. All parameters seem to be in check other than trace amounts of nitrate. Only thing I can think of is to move around liverock in case cb has been harassing it lately. Any other ideas/suggestions?

29 long gal tank
pH = 8.2
Ammonia = 0
Nitrite = 0
Nitrate = 10

Sometimes a shy fish isn't feeling well. You might want to look very closely for any other symptoms that are more diagnosable than shyness.
