Hi, I recently upgraded my 40b to a 115g reef. The fish that came over from the 40b were: 1 Clownfish, 2 blue chromis, yellow watchman/pistol pair, and a bunch of corals. Over the course of the last two months I added a fox face, lyretail anthias, neon dottyback, and a kole eye tang. Last week, all of the new additions died over the course of 4 days. The only fish with signs of anything were the foxface and tang. It looked like what seemed to be ich but they were eating but with how quickly they died I suspect maybe it was velvet. Everything left in the tank, the original from the 40b, have been fine except that for the last 3 days my clownfish has started getting weird spots and I’m not sure what it is. Her behavior has remained the same and she still eats as much as she can get. I’m not sure what these spots are. But I have attached a video, can anyone help to identify what it may be? The chromis and watchman have no spots at all.
