I recently purchased blue Cespitularia Xenia, and a pincushion urchin. They both were doing great and one night when i came home from work the coral was "melting" and the urchin was slowly escaping off of the frag plug. Is this coral save able? if there is anything i can dose to help it. The coral was 2-3 inches high and about 1/3 of a penny base, now it is the size of a penny base wise and height. It is also trying to move off of the frag plug. PLEASE PLEASE HELP ME try and make this coral come back to its former glory.
