I'm thinking the one part of my torch coral has brown slime disease. My trumpet, zoos, mushrooms, and polyps are all fine. The torch coral has only been in the tank a few days. If it does have brown slime disease I need to frag it to remove the affected section. Can somebody draw a line on the picture to show exactly how to cut it? I've never fragged a hard coral before. Can I use a hacksaw or should I go buy a dremel?
