Powder blue or Gold rim?

Powder blues are beautiful fish but they are aggressive. I love mine but he is a real a**hole towards every fish.

 

Thanks for the input, I keep hearing that. My Kole tang of all the tangs is the worst. They're supposed to be less aggressive ??? The one I bought looks alot like the one in your pick 3315. It's slightly smaller then the Yellow, sailfin , kole , Tangs and a quarter the size of my regal blue. I also have a flame angel that's slightly larger.
I hope they don't bother the Powder too much. From what I'm hearing when It grows up the others better watch out ! So these fish just play follow the leader all over the tank, excluding the regal.

 

Whitecheek tangs are cool and a bit rarer than your normal PBT.

 

I did see some whit cheeks, but they look rather pale in colour. Does this change with age/diet? With my tank being 7ft long I'm looking for some fish that stand out. So far I have 3 ocellaris clowns ,1 black ocellaris , 6''Regal blue, a sailfin tang , kole tang, powder blue tang, yellow tang, flame angle, cleaner wrasse , 2x p.j cardinals. 2x cleaner shrimp, 15 ish crabs, 6 turbo snails, and a Mandarin goby.

Not looking to add much more, but there is quite a bit of empty swimming room ! Any ideas, thanks !!
