Clown fish acting strange?

[Capttully]

I am fairly new to the hobby with my tank being 4 months old now. I have a 75 DT mixed reef with a 29 gal sump. My params are ammo=0, trites=0 trates=10 api salinity 1.025. I have 1 yellow tail damsel, 1 Yellow belly damsel, 2 blue damsels, 1 Yellow tank and 1 Black&white clown.
Well seems though he likes to swim back and fourth all day. If i put my hand inside the tank he comes to it with no problem. This morning i see him up nearing the corner of the tank, not sure if they sleep or not. Seems like he was very lazy. on its side turning over. then he will perk up and move around. I am not really sure what kind of behavior to expect. Should i be worried?

Some of mine sleep that way, on their sides and they look dead at the top of the tank.

I am sure the fish is fine.

This is completely normal behavior Clown Fish are simply weird fish in my experience. I have a pair that sleep on top of each other swimming up and down the corner of the tank all night long.
