my pair of false percs sleep in the front corner of the tank. the dig a hole down in the sand next to the glass and sleep in it every night... even if i fill the hole back in in the morning they will still dig it back out every night. they never stop moving either and ther sleep on top of eachother
Here's a really old vid of my clowns at night (under moonlights). Sort of boring/intriguing in a way. They didn't have an anemone at the time so they mostly roamed the surface.
