The first thing is to give the fish time to get itself back to normal, or nearly so. Right now, I am seeing one possible scale that looks infected, so I wouldn't try to treat for that. If the fish is breathing, it will most likely come around, being out of water for an extended time is traumatic, but if they will still move water over the gills on their own, most of the time they will recover. No need for any treatment except excellent water, which water changes will help with. Do you have test kits so that you can give us test results, numbers, for ammonia, nitrite, pH (morning and evening), KH. There may be some additional information that we can provide to help, not only this fish but the others as well.
