The fish that had ich was my Watanabei Angel, not the goby. It did have ich. It had it very slightly (about 10 little spots). They would get bigger and then gone. They would dissappear for about a week before I'd see them again. It never got bad, always about 10 - 15 spots. It lasted for a month and wasn't going away with just the garlic and ginger. I also added a Neon Goby. So, when I got back from vacation, I got the Seachem Metronidazole. After a while of adding it to the food every day it went away and hasn't returned and it's been months. Not sure exactly what cured it, but it was probalby the Metronidazole. And it certainly appeared to be ich. Metronidazole is supposed to cure ich if the fish eats enough. I just recommend giving it a try if you can't get all the fish out. I won't dose it in the water, just feed it.
