Angel suggestions for SPS 125

[yellowtruck75]

I need angel suggestions for my 125 SPS dominated tank. The fish I have now are a powder blue tang and a copperbanded butterfly. I want and angel that won't get huge in a 6' 125 and that won't hurt my SPS and clams. I need suggestions and pictures if possibe.

 

[Kahuna Tuna]

For that size tank I would stick to one of the smaller species like a Genicanthus, they are the most reef safe angel as well.
