Picture of the tank, please!

BRS has a good article on beginner fish, although don't just go ahead and add all of them! A 20 gallon tank is a rather small tank still, so keep this in mind.

I would go looking for a Royal Gramma! Very pretty and enjoyable to watch. That one and a Banggai cardinalfish.

A lawnmower blennie could be an option too although I would say your tank might be too small for one of these.
