Wow, how did I forget that? Another great recommendation Stephane! Cleaner Shrimp are invaluable for dealing with Ich, or any parasitic illness. I don't know if my Tang would have made it without the pair of Cleaner Shrimp to help out.

And not only are they useful, like Stephane said they are nice to look at, and provide your fish and corals a great nutritional treat when they spawn every few weeks. Of course you must have two or more for this.
