Abscess

Hi there! Fanny has a small abscess above her right eye. I’m thinking salt bath? She was last salted a few months ago when she had fin rot on her tail. She’s still my only fish, so could do the tank, but that’s probably overkill, do you think? For the bath, is it one tblspn peer 10 gals water? And 3 minutes?

Hope all is well with you, Venus.
