I cured my Oscar's HITH with a course of metro and the one-time addition of a "vitamin and mineral pyramid". Now I feed him more live than before and the HITH has not come back. People underestimate the value of insects in fish diets. Once a week I give him about ten to fifteen large gut-loaded crickets and that keeps him in tip-top shape. Well, that and keeping nitrates below 20ppm. I also buffer his water with crushed coral currently, which is probably beneficial but I'm not sure. No salt, no elevated temps needed here. Just metro, minerals/vitamins and improved diet with more insect action. Never feed goldfish, they are poison. Earthworms are amazingly perfect Oscar food, though.
*Looks like you've caught it early enough to turn it around completely! She's so little, is she only a few months old? What size tank?
And hikari cichlid pellets are about as good as corn flakes. At least switch to massivore and algae wafers.
