A got a molly a few days ago and when I got home I saw 1 spot on her tail, but When I looked closer it looked like an air bubble so I didn't think much of it. I know I should've quarantined her but I don't have room for a quarantine tank. Today I noticed ick on all 6 of my mollies. I think ick was one of those diseases where you should treat the whole tank but I'm not sure what to use to treat it since They are in a planted tank with with a few mystery snails and cories ( which I know are sensitive to medication). I have ick-x but I wasn't sure if I could use that with snails, plants, or cories. How should I go about treating my tank for ick? Thanks in advance.
