I come home ceck my tank and my purple tip frogspawn is covered in brown jelly.One of the five heads is completely gone. I have had this peice for nine months and it has been fine.I aslo have some anchor and torch they are fine so far. One of the power heads has been turned away from this coral for about 2 weeks other than that no change. Help me save my coral! Any treatment? Anything to prevent in future.
