Adding a tang/fish to tank...??

[mrp2g]

Hi everyone... need some help. I have a 150 reef. I currently have a hippo tang, a red sea mimic tang, a purple tang, fiji foxface, midas blenny, sand sifting goby, cardinals and chromis. I just recently lost a blonde Naso, which has been with me for 3 years. I want to add an additional fish ( preferbly a tang) to my reef. This core of tangs has been together for about 2 years. Do you recomend this? should I look at another type of fish? Should I stand put with what I have?

I personally wouldn't put anymore tangs in a 150.
