i was looking at my fish last night and one of my zebra danios has little white spots all over it. im pretty sure its ich. I have mollies, platy, neon tetras, cherry barbs, guppies and cory cats and zebra danios. I dont have another tank so i have no way of isolating the danio with the white spots.. What is the best way to cure this. Is there a good store bought treatment? Salt and hight temp? please help id like to get this cleared up as soon as possible
