Flame Angel

Personally I wouldn't consider adding any tang into that tank as even if you get a small one it will outgrow it fairly quickly. Take a look at the wrasse family - some stay fairly small, are colourful, and very active. Another option for you may be firefish (one of my personal favorites) but they can be jumpers so you have to be careful. I have never had one jump and I have open top tanks but have had two eaten by a large carpet anemone! No more firefish for that tank until the anemone finds a new home and I can't see that happening for a while.
