I was wondering if anyone has ever experienced this. I had a pretty nice looking green acro that I noticed had some red bugs on it. I immediately took it out of the tank, dipped it in Seachem Reef Dip, lightly scrubbed it with a soft toothbrush, quickly dipped it in RO/DI fresh water and placed it back in the tank. I noticed pretty much immediately it had lost its coloring. His tissue looks undamaged and hit polyps are out but color is like you see in the picture. Here is a before and after. I can't tell if it is browning or bleaching or what its doing. What do you guys think?
