I am curious if it's common behavior of Hoeven's Wrasse.. every night about 1 hour before lights out, my wrasse would swim in circles in two areas of the tank, possibly surveying the area for safe sleep. He'd do this for about 15 minutes before burrowing himself in the back corner of the tank where he usually sleeps (45 minutes before lights out). It's clockwork, every night, same time.
my other wrasses do not exhibit this behavior (Yellow coris, red-head solon and leopard wrasse). These guys just take a dive into their sleeping areas minutes before lights out.
