HI - My flame angel has popeye and wondering if safe to treat my reef tank with Maracyn Plus. I just don't want to hurt my soft corals and invertebrates for the sake of one fish. No way to catch it without taking out a lot of live rock which would be harmful on everything too. Thoughts or advice? I have a 65 gallon reef tank with a 120 gallon acrylic tanked turned into a 50 gallon staged sump.
