sorry to hear that, sounds like you are doing everything you can. how long did black clown last after you noticed the spots?My boxfish is still covered, but seems very happy. I posted another thread after the company that keeps up my tank accidentally dosed my DT with copper instead of my QT tank. So my nems and corals died. At this point, I’m just going to dose my DT and kill all of the parasites and go from there. My black clown died unfortunately but everyone else is doing well.
