my bristlenose and the heater

My Molley and beta do the same thing in my community tank... interestingly enough they seem to do it when its off too though
 
I believe it is just for cover. Do you have driftwood that he can hide behind?
 
my little guy seems to love chillen under the heater. Is this because of the heat itself or because of the cover?

All good possibilities, maybe just ask him why he sits there.....:grinyes:
