clown fish disapeared

[sawduster]

I have two clown fish and when I came home this afternoon one has disapeared or hiding in the live rock ..should I be concerned? I fed them as usual and he did not come out to feed ..any ideals out there?

Do you have a Aquapod or a JBJ or because I might know where he or she would be. If you do have one of those tanks look where the filter is and the other slots and thats where he might be because thats where mine was but it was a pain in the butt to get him out
