What can cause this? Insufficient flow? Will my other corals catch this?

Please help ASAP!!!!!!!!!!

soft corals do shrink without notice. do not direct the water flow to them. keep calcium high 450 mg/l, and kh 11 odkh and it will recover soon. if it has fleshy areas try to rinse it inside the tank with the flow of a power head. add some iodide in the tank half dose according to the manufatures, that will solve the problem in about one week. best wishes.
