I got two acro frags and some {one more thing that I think is the problem but don't want to blame it yet until I see if anyone else had problems similar to this}. Well about Tuesday I notice that 3 or my fish look like crap-o-poopoo. There skin looked like it was just falling away or something. They were, yes were, my clarkii, royal gramma, and mandarin. All have been healthy, fat, and happy for at least 8 months and two for almost 2 years now. By Thursday they were no where to be seen, and my serpent is very very large. Anyone have any problems with fish after adding anything from the swap?
