Hi all

Didn't notice anything last night but today morning notice that one of my female CPDs kept hanging out at the top of the aquarium, edges of fins look a little weird. Closer inspection, notice some sort of whitish growth on the mouth. Couldn't do anything just then as I didn't have any salt or medication on hand other than paraguard and I had to rush off to work.

Thinking of removing her when I return from work this evening and QT her in a bucket for now. Do I have to medicate the main tank? Thinking of going for the salt route but I have some plants inside, just java ferns and anubias. Since they are just anchored on rock and wood I can easily remove them during the salt treatment. Some people also suggest kanaplex and nitrofurazone combo. Any ideas?
