Hello all, this is my first post on here and I first want to say thank you to everyone that contributes on here. This place has helped a lot this past few months. And although I’m still struggling to find balance in my reef tank, I’m thankful for all the advice I have found on here. Now I wanted to see if you fellow reefers could help me save my last fish. I had a total of four and so far 3 have died. Please keep in mind I’ve had all these fish for months and I did a 30+ day quarantine on them following the instructions on the humble fish website when I first received them. The last fish I have is a chocolate clown fish who unfortunately seems to be hanging by a thread. When I first pulled him into the QT he only had what looked like ich. Multiple white spots. Spaced out and really apparent. I gave him an H2O2 bath (30 mins) and released him into the QT at 1 ppm copper power (checked by Hanna). Day two I raised the copper by .5 and today again by .5. But after I dosed the tank and took a closer look I realized he had gotten a lot worse overnight. Significant fin rot and also some sort of discoloration. In a panic I doser metro, kanoplex, and nitrofurazone as it seems bacterial. I just wanted help identifying what he might have, if I took the right steps, and what my chances are. Thanks again everyone. I’ve lost them all and this guy is my last one and I am really hoping he pulls through.
