I have a 72 gallon bow front tank with coral, I'm running two fans, and a fluval 406, for main filtration, I was doing so well with my two tangs, one a powder brown and the other one is a dark Blue tang (not sure of specific name at moment) but either way, he just developed ick last night, I discovered it when he came out around midnight, and now my powder brown is starting to get it as well....does anyone know a medication that can be used to cure it and zap it a.s.a.p...That is also safe on corals!! I can't afford to lose these fish...I'm hoping that someone will have some idea as to what will work the best out there, and where I could get it NOW!!! Look forward to hearing from someone...thanks. :wave:
