Do you know how your fish sleep at night? My cleaner wrasse sleep curled in hole in the LR. My clownfish inside his anemone. The shrimps hanging on the live rock. The royal gramma sleep hidden in rocks. My chalk goby and flame firefish sleep under the LR in sand...and my crabs never sleep at night :)
mine has his very own rock he vanishes into at nite and he goes in at the exact time, night lights on or off
