My sailfin tang lays on his side against a rock every night after all the lights are off in the room and tank. My dottyback sleeps in a hole in my lr and my clowns just stay around the top of the water.
when we briefly had the trigger it slept on its side under a rock formation we had set up. the clown hide behind a big rock. i've never seen the big damsel stay still or stay in one place...he must sleep when i do.
I have this giant conch shell in my tank and my yellow tang and tomato clown both sleep in there togeter.......hmm...
Could be strange ofspring...........lol.............tomatotang
