might look like it's working, but ich comes and goes in my expierence (until it can't infect the fish anymore). If this garlic is doing it's job right, you should be feeding it(soak thier food in it) to the fish, otherwise it's nothing but a preventitive measure, wich is'nt what you need at the moment.And oh yess, you should NEVER buy a cleaner wrasse, otherwise your just helping to suport the hundreds of them wich die in captivity.
