Parameters in terms of did anyhting occur to cause a swing in Alk or PH? Salinity swing? Temp. swings? New tank mates? Any "turf wars" between inhabitants? Changed salt mixes? are you overdue for a waterchange? Any can cause stress to species prone to ich.
If you've been feeding flakes, try frozen foods. Not too many fish will refuse frozen mysis. If it's a vegetarian afflicted, try hanging a sheet of nori or other dried seaweed sheets in a clip. If it's a bigger fish, try Piscene Energetics mysis, it's much bigger than Hikari.
I've never needed to try garlic elixirs, but I would imagine any would suffice. Maybe someone with specific experience with a particular brand can chime in. You simply apply a few drops to some thawed frozen food, or even flakes, and let it sit for a few miinutes. You can try the same with Selcon, though sparingly so
you don't foul water quality.
