So bit of a weird one,

My amano shrimp is molting and as the title displays some air bubbles from the air stone have been trapped under the molt, and so hes kind of just floating around trying to get it off, is there any way I can help him or will he be alright. Heres a picture, Kind of a weird site, ngl.
