Clownfish Behavior

[namwodahs]

I've had a clownfish for a few months and every night after my main light shuts off he does this thing where he goes to the bottom of the tank then kicks up a bunch of sand with his tail. He does it pretty much every night so I'm assuming it's normal behavior. Or is it?
