Help with deciding a safe new addition

I have a 125 gallon tank, the tank has been established for 6 years but was empty with no lighting but still had water circulation for a year. I recently got the tank back up and running and I am somewhat a novice at what fish can go with one another.



My tank is 125g, 55g sump w/ refugium, 40w UV.



My current stock is as follows;



4 Ocellaris Clown fish



2 Blue Hippo Tang



1 Foxface Lo



40lb live rock/no coral.



I had some stock die in shipping from live aquaria but I have to add a fish to the order to get the replacements shipped back out ($29 minimum, had an entire bag of snails die in the bag, total snails : 10).



I am looking at the following fish, but seem to be slightly discouraged whenever I do much reading into putting them into my tank. I am only wanting to add one of the following, not all of them, these are just the ones I am interested in.



Powder Brown Tang



Powder Blue Tang



Achilles Tang



Green Mandarin



Yellow tang



White Cheek tang



Coral Beauty.



I love the tangs. Our current tangs are brand new to the tank and are a little bigger than a quarter.



Would any of these make a decent addition to the tank? I currently feed Omega 2 flakes, Mysis shrimp, Blood worms and Brine Shrimp with Kent Marine Garlic Xtreme along with Nori.
