Do i really need salt?

NONO NO! I think I must have accidentally used some equipment from my infected tank on one of my other tanks! My rainbow tank seems fine and I'm going to start reducing the heat soon but today I found spots on my dwarf gourami and 2 of my 5 cories! I've starts treatment ASAP. I don't remember using any contaminated equipment but I must have! There have been no new fish to that tank for at the very least 2 months. I feel so very stupid right now and I was being so careful! I've cleaned everything with straight vinegar then rinsed in hot water so I'm hoping it's killed it all.

Don't beat yourself up. You've already started treatment so things should be fine in a couple of weeks.
