Need suggestions for additional fish

[jsharp13]

Have a 120 gallon with a 20 gallon sump.

Currently in the tank:
2 Ocellaris clowns
Magnificent Foxface
Bristletooth Tang
2 cleaner shrimp
2 sea urchins
Various coral, mostly soft (bubble, frogspawn, brain, leather)
Also have a Mantis that was a hitchhiker. He has left all of the fish alone except for a Goby that I'm fairly sure he got because it was a bottom dweller. He has never bothered the Foxface, who sleeps on the bottom of the tank (I'm assuming because he is too big).

Looking for a fish that will get fairly large and is colorful. I love Triggerfish, but I know those won't work because of aggressiveness. Love large Angelfish, but I know those will get too big. I like the look of Dwarf Flame Angelfish, but really looking for something that will get bigger.

Any suggestions?

Regal Angelfish

Good option ^^^, but I would be concerned about adding the Regal to the tank with that established Tang and Foxface. Take a look at the Keyhole or the Eibli Dwarf Angels. The keyhole gets 6-8 inches and the Eibili will get around 5-6. Also you can look at the Bluespotted or Cream Angel.

pyramid butterflyfish are always good, they are peaceful, and are 100% reef safe. Regals are good. I would suggest adding some smaller fish though, because it looks like you only have 2 "big fish" and a pair of clowns. you might wanna add a few wrasses or other small fish
