Hey everyone. So I have a 135g Mixed reef. I believe that my Blue Hippo Tang (newest addition- added 1.5 months ago) got Brooklynella and gave it to my yellow tang. The hippo is looking in very rough shape. Discolored patchy face, jagged fins, not eating and hiding (2 -3 days now). I hadn’t noticed the first day or two due to being at work and getting home late. Finally I noticed on day 2 or 3 (today is day 3). Also noticed my yellow tang won’t eat and is hiding, but swimming up right, but is breathing heavy, hiding and not eating either. I was able to catch my YT and set up a QT system. Assuming it is Brook, I got ParaGuard since it contains Formalin and dosed accordingly. The QT is a 20g long, has a heater, hang on the back filter, air stone, small wave maker, 1 rock for hiding (and for some bacteria since it was from my display) and also added a small amount of turbo start for more bacteria. I’m going to get copper power in the morning to add as well. If anyone has any other suggestions on what to add to the QT or about Brooklynella with tangs please let me know. None of my other fish are showing any signs. All look fat and healthy, eating and swimming as normal. (All water parameters are normal and haven’t had any swings) I attached some pictures and a video of the yellow tang if that helps.
