Scarlet Hawkfish hiding & not eating?

[aquaruss]

Does anyone know why my Scarlet Hawk fish is hiding all the time & does not appear to be eating?
It only seems to behaving this way since I moved some live rock around & I'm sure he didn't get knocked :help:
Water is fine, 160L tank, 20L water changes weekly.
Any ideas I'm rather worried, he's been like it for 3-4 days now :huh:

He's probably just a bit stressed. Try coaxing him to eat with a little frozen brine etc. You probably realigned his territory and he's just not used to the new arangement yet. You might also try a live food like a small ghost shrimp etc. to see if you can whet his appetite.
