I need help identitying what meds to offer this Platy. Three weeks ago, I noticed this Platy's scales looked flaky. Is this a fungal infection? I treated the water with Seachem Stressguard daily. I then fed her a daily food soak consisting of Daphnia, Garlic, and Maracyn2. 7 days later I didn't see any improvement. I continued Maracyn2 but then added Paraclense for another 7 days. There still hasn't been an improvement.
Should I switch the food soak to a gram positive bacteria antibiotic such as Maracyn? Then add Ick-X?
She's currently in a community tank; Mollys, Platys, Albino Corydoras, one Mystery snail, and three nerite snails, and of course hitchhiker Ramshorn snails. My quarantine tank is full with new fish, so that's a no-go. I do have a 2.5 gallon hospital tank. It was recently occupied but that fish was successfully rehabilitated and will return back to their tank today. I'll probably move the Platy in there. None of my other fish in the community tank have shown any signs of illness. They've been under the same food soak protocol as the Platy. She is eating and swimming around but has periods where she hides like in the attached pictures.
