About 2 weeks ago had a flame angle die. No signs of ick or other disease (pic below). From about that time I also have not seen our gold head goby who lives in one of the rocks.... feared dead.Then this morning my wife txt me and says many of the fish have white spots (they were fine last night) (pic below). Then by the time I get home this afternoon, less than 5 hours later, two of my clowns have died..... I am going to do a fresh water dip and start treating with non carbon Ick be gone stuff....As of about a week ago all my levels were fine..... almost all 0's for ammonia, nitrite, nitrate.... PH was about 8.3 I think. A few weeks a go I added an ATO and it messed up and brought the salinity down.... but this has been fixed for at least a week. What could this be? Does Ick kill that fast! over night?Also, there are these white spots that started showing up on the back of the tank.... Not sure what they are and if they might be part of it.
