Wrasse recommendation?

[Asureef]

I'm looking for a reef-safe wrasse for my 28g nano. I have 2 percula clowns, Helfrichi firefish, and a hi-fin goby w/randalli shrimp. I had a McCosker's Flasher Wrasse and a 6-line in the past. The 6-line was a little devil, though the McCosker was quite mellow and I've considered getting another one but would like to see what other options I may have?

I think the common name for this one is cryptic 6line wrasse?

Supposed to be very nice, small, hardy, and peaceful...
