If you can find cleaner shrimp or neon gobies (CB had both a few days ago) do not expct a quick miracle. These are effective means IF the fish allows them to clean him. Also, they are slow and steady. If you have a pretty major case it will take a while to clear up. The cleaner shrimp and neon gobies are, in my opinion, something that everyone should have in the tanks as a preventative. They are extremely effective in wiping ICH out before it becomes a problem.
