Great timing for this thread! Came home today and a Rusty Angel has a white spot on his side and a matching one on the fin that touches that spot. I've had the fish 3 months. In a reef tank. Can't go the traditional route with copper based meds. Off to the store for some garlic and ginger. BTW, this is my first problem of this sort, does one prepare garlic the same as you described the ginger?
