Do my Clowns look sick?

[Mr.Mcgibblets]

Two weeks ago I bought a 10 gal tank that was setup at a LFS it has LR, LS, some crabs, snails, and 2 clown fish. Everything has been going well, I have changed the water 4 or 5 times since I have had the tank, tested the water daily and all seems normal.

Temp 80
Salinity 1.024
Ph 7.8
nitrates 20
ammonia 0
Phosphate 0

The clowns seem happy. They have been mating for the last week but in the last couple of days I have noticed some spots which look like dust on one of the clowns and the colors on the other clown do not look quite right to me. I have done some research today so I know just enough to be dangerous could this be Brooklynella? Pictures attached.

Lost both clowns, one during the night and the other this morning. I feel terrible, but at least it wasn't from something I did to the tank.
