Hi guys, let me start with a short description of my tank. Its a 150g SPS reef that has been with me for over a year. Everything was doing great till just a few days ago. I use biopellets, a XP3000 skimmer(rated 350g), and i run AC all in my 80g sump.
Here's the problem: 2-3 weeks ago i asked my friend who was going to singapore to purchase a mitratus butterflyfish for me. When it got home, everything was okay and it was eating by the next day so i had no reason to suspect anything wrong. I went away for 5 days and left the tank under the care of my brother as i have done many times in the past and when i got home everything was still okay except the mitratus was discolored, its eyes were cloudy, it wasnt swimming out in the open anymore and its scales were falling off.
I thought immediately that its probably flukes because of the cloudy eyes so i treated right away with praziquantel and did a FW dip but that didnt seem to help. It died after 2 days and i thought maybe i was just too late to save it. I did a FW dip to confirm if it was flukes but looks like it wasnt. The cloudiness in the eye never left and nothing was coming off its skin but scales. Yes, i did double check if it was scales and they were.

The next day, my other mitratus and declivis butterflyfishes were acting all weird. They were still eating a lot but they were discolored. I added more selcon to their food and hoped that when i get home from work, they would still be okay. When i arrived that night, the declivis was on its side and the mitratus was looking even paler. I caught them both and immediately set up a 40g hospital tank and placed them both there. I was already so confused as to what it could be. My friend got a fish from that same batch and his fowlr was getting wiped the same time as mine and he suspected that it was brooklynella. I immediately added furan-2 and formalin to the QT in the hope to save them but by the next day, the declivis was a gonner and the mitratus wasnt looking good anymore. That afternoon, it died as well. I tried comparing their pics to those of fish affected by brook but im not 100% convinced it is but it’s the most likely candidate I think.
Pics of the 2nd mitratus and declivis. You will notice that the eyes of the mitratus and the declivis arent cloudy like the first mitratus.
Today, one of my randal anthias and my royal gramma(both have been with me for more than a year and were super healthy) died.
Please guys! HELP ME!!! I know i should have put the mitratus on QT but the LFS already had him in QT for over a week and they assured me he was good to go.
My next step now is to catch all the fishes in my tank by tomorrow morning and treat them all. As to what i should add to the hospital tank, im not sure yet. Please feel free to add comments!
