My Blue Linckia Sea Star wrapped itself around one my Hydor Koralia power heads last night. I shut it off and removed the star this morning, but there is some damage to the underside of one of the arms near the the center disk. About 1/2 inch of the skin has been torn off, from the suction created by the power head. My cleaner shrimp have been picking at the damaged area. The star is moving a little, but the arm looks really bad. Any thoughts on the approach I should take?
