Clown Antics

[1boatnut]

I have an Ocellaris Clown that has started doing something strange,or at least I think it's strange. It has started to stay in a large visable hole/cave in a piece of live rock.Sometimes it even looks like it is lying down on the rock.
It eats normal and seems ok in every aspect.All my water parameters are fine.
Does anyone know,does this fish want to host or something?

normal, the hole is his little home, mine uses my green brain as a home
