1 or 2 Fish suggestions

Hey, just trying to finish stocking my 120g reef tank. Current inhabitants include: yellow tang, tomini tang, false pecula clownfish, six line wrasse, diamond goby, niger trigger, watanabe angel(female). Any suggestions, always open to hear what others have to say about this hobby, also just replaced my diamond goby as I lost one about a month ago, amazing how much of a housekeeper of the tank he was and is.

 

You are forgetting the most important fish of all, a foxface. Cleans my entire tank for me!

 

I like firefish and clowns. So I would say a buddy for your current perc or a red or purple firefish.

 

A foxface would indeed be nice, Few of them have a tendency to not be reef safe ish, but just research what you get. My suggestion would be a wrasse pair. They are quite lovely to watch. Flashers are fun .

 

Some sort of Blenny(Algae, Starry, Bi-Color, Ember)!
Royal Gramma
Cardinal

 

It's been mentioned already, but a Royal Gramma. Very bright and colorful and (at least mine) very passive but active.
