I just noticed one of my danios has a little fungas growing on his tail. Looks the same as what one of my goldfish had about 2 months ago. Separate tank of coarse. I treated my goldfish by adding salt to the tank for a few weeks. Can I do the same with this tank. Here are my fish that are in there. Danios, White Clouds, Platys, Bleeding Heart Tetras, Blue Rams, Iradescent Sharks, Pepper Corys and otos. I know the salt would be okay for the danios, white clouds and iradescent sharks as they came from a tank that I had salted before. The others I am not sure about. If salt is a no-no what do you suggest I use. :huh:
