how do saltwater fish sleep so weird?

how do they?

when i shut off my tank lights at night, the reef literally dies, everyone hides to sleep. all i see besides corals are the arrow crab and coral banded shrimp food hunting.

so far i can never find where the yellow tang or damsel sleep, but i know where my goby sleeps, he has a tunnel in the argonite.

my pink skunk clownfish sleeps the weirdest way. he goes beside the powerhead, and sleeps perfectly vertical with his nose straight up, and somehow stays PERFECTLY still, not a flinch

That's nothing. My clown either sleeps completely sideways not moving at the surface or he sleeps sideways on top of my powerhead. The top of it is only about an inch from the surface.
It's weird but amuzing. The first few weeks I had my fish I thought they were dead every morning.
My firefish just goes and stuffs himself inside a piece of my LR.

lol, thats what my clown goby does. under a monster 8lbs piece of my LR he has a huge tunnel that hes always in.

My fuzzy dwarf sleeps either vertical or upside down on a LR its pretty funny.

Yea.... my clowns are nuts.... When the daylights go off and the acetics are still on, they start to slow down, and as soon as the acetic go off, the male floats sideways and sleeps and the female hides in a LR cave.... silly things.
