Clownfish behavior

[4luvoffish]

We recently got 1 ocellaris clownfish about a week ago. Then recently bought another ocellaris clown fish a couple days ago. They seemed to be getting along and still are. My question.... my male has been hoovering over the sand bed, but only in one spot kind of like shaking his rear in fast passed. Is this raise for concern or is everything ok?

My male does that all the time in an effort to attract the attention of the female.
He will also make popping a sounds with his mouth on occasion, whenever he seems a bit peeved at her.
