Clownfish acting weird, any ideas?

Hey, I noticed my clownfish couple acting weird for the past couple of weeks.

Thoughts?

Mine have done the same thing. They made a depression in the sand in the corner of the tank. They use it to sleep at night.

I agree with that, they seem to be making a bed, testing if it is deep enough to shield them from the current and digging an indentation to hold them calmly for the night.
