OK I appologize for my behavior. I didn't take into account that you may not know what you did.
From your perspective I think you believe you did your other fish a favor by getting a parasite predator to clean off the Ick.
From my perspective you purchased a fish that you knew would soon perish in your aquarium. A Cleaner Wrasse will not cure Ick, just pick at a few of the visible parasites before it slowly starves to death. Cleaner Wrasse have an extremely important function in the wild and removing them from the reef has been proven detrimental to the fish populations there. Buying a Cleaner supports this capture & removal.
Sorry I went off like that, it's just a sore subject with me.
