I've been battling ich in my quarantine tank going on 3 weeks. In my tank I have 6 black neon tetras, 1 guppy, and 1 dwarf gourami. My question is the guppy and the tetras had ich and beat it, but my gourami has it bad. Can I move the guppy and the tetras to the main tank and aggressively fight the ich on the gourami, or is it best to leave them all in quarantine until the gourami beats it? I'm using ICH-X currently. Thanks everyone!
