Clarki Clown in need of something


In Memoriam
I have a very large Clarki clown that has white patches on its body like its slime coat is dissappearing and the scales look like they are starting to seperate. I put some stress coat in tank to help me get some time while I get on here and find out what others can tell me to treat this clown with. Its acts like it is dying slowly and not moving bery much. I have pictures I can send to anyone that thinks they can help me. Please post comments and suggestions. Thanks
