What blue do I do?

[Charley]

Have a Red Sea 450 reefer (90 gal) and would like to add a blue fish to the tank. Currently have:

Yellow tang - boss
Flame angel
Bimac trio
Chalk bass trio
Pair of clowns
Foxface
Bluestar wrasse
Watchman goby w/pistol shrimp
Algae blenny
Mandarin
Bunch of various corals

So far a peaceful tank......pop always wanted a pop of blue.

Hippo tang? grows too large I guess
Cherub angel.....maybe eats coral.
Sigh..
