Odd Clown Behavior

[Happygo663]

Recently my female clown is lumbering around and sucking on the mushrooms in the tank. She seems to be doing the distal floating thing almost as though she is nose diving into the sand to pick up scraps, even though I feed them plenty of flakes. (Like two punches a day) New to this and wondering if someone can give me some answers - should I be concerned? pics and video attached
