Anybody else's trochus do this?

My trochus will go all around the tank at night, and then by day he will come back to this exact spot and sleep.

I do think a couple of mine have preferred spots in the tank. Pretty neat.

I have not noticed this with any of my trochus but one of my large turbos definitely has a sleep spot it returns to every night/morning.
