The last two weeks have not been so good I started noticing what looked like dust on my fish in the small tank. Fish eating good but starting to have problems. Read up on ich which seemed to be larger cyst than this but try what was advised. Lowered salineand raised temp,dwarf angel,two stripe damsel and arrow crab killed over.Saline was at 19 to 20 kept that way for a week yesterday lost red skipper and cleaner wrasse. Started to raise saline slowly this morning found clown dead, :cry: now not sure what to do only have domino and firefish left. I can't tell if firefish is effected shows no signs but domino is covered in what looks like dust. No, no pics camera wouldn't do that close up. Lost my tank dont want to lose more,want to find out what this is and treat before new fish come in.
