So I took these brevis to the swap meet yesterday and no one bought him. Well as soon as I got home, I acclimated him properly to the tank and after dumping him in I noticed he had some fungus on the top of his back. I treated the tank with Melafix (I know it probably doesn't help) and went to bed. I got home tonight after work to find him almost completely covered in it. I removed him and put him in a quarantine tank. Is there anything else I can put in there to help him? I don't have Pimafix, but I do have salt. Can I do a salt treatment for him?
