I believe my African Dwarf Frog is starting to come down with a fungal infection just a little spot. In Melafix they use the essential oil Cajeput. To avoid all the other additives in Melafix I decided to research my own essential oils and found Doterra Essential oils garenteed to be 100% pure. I was going to dilute the oils to the same percentage in Melafix, 1%. Sound like a good idea?
