All water levels are normal in tank, 95 gallon freshwater community tank, 5 Tiger Barbs, 1 silver striped Angel, 1 pleco, 2 kuhli loach, 1 BGK, 2 Molly's. Brought home a black Molly last night, looked great at LPS, woke up this morning, looks like the neW Molly has ich spots. I immediately took him out of the tank, are other fish still in danger of getting Ich? I'd rather not stress them with a treatment if I don't have too.
