Hey guys, well I'm positive that my angelfish has a gram positive fungal infection and possibly a few other fish in my 30 gallon. What would be the best medicine to treat such a disease? I've tried some really strong meds but none have worked so far (can't remember their names). I'm afraid if I treat with anything to strong that my Asian bumblebee catfish could get sick since to my knowledge they're fairly sensitive to medications. Looking for any suggestions you guys have.
