I figured it out. By the next morning my sailfin was completely covered, chromis had a few spots and the lawnmower had a few.
I started soaking there food in garic elixar and dosed kick-ich. The sailfin has a few spots left, but everyone else is ich free. The bottle said coral safe but my cup doesnt seem to be quite as extented. I think the cup will be fine color is still great, so I dont know if I would use it if I had abunch of corals.
