I appreciate everyone's feedback. I think a kole will be my first choice, followed by whatever they have that everyone's suggesting. Let's see what the LFS have. This is the feedback I was looking for.
Also, regarding levels, my parameters are fine and I don't have any algae issues. The tang will go into a standard 125 tank that's I'm using as my growout/frag tank, that's all plumbed into my 180 gallon display. I'm running a 75 gallon macro refug with 3.5" sand bed, a MRC GFO reactor, and 3 Korallia powerheads in the 125. That's why I'm not really concerned about the appearance of the tang, just prefer something on the small end (although the kole is a pretty fish).
Thanks again.
