I have had a few tangs with what appears to be a flesh eating disease. It starts out looking like Ick but then progresses to very small ulcerations, fraying of the fins, and scale loss. The fish seem to eat up until they die which is about 1- 2 weeks. I currently have a sailfin with the disease and he is in a 10gal tank and I am treating him with maracin and tetracycline. Any suggestions would be helpful
