Most sites that have them for sale will have a picture of them. It is a very cool fish and altho a member of the Wrasse species they are a bit bigger and bolder with larger fish. There are a few that are around a lot and they are
Dianas
Lyretail
Spanish
Cuban
Coral
I have posted before of my fondness for these fish since getting the 4 I have now (Spanish juv, Diana's adult, Coral Adult, Coral Juv. Note; all in different tanks).
Lyretail most mellow, Cuban deep water harder to find good one and they are expensive compared to others 50-60 bucks, Spanish and Coral pretty good tankmates for othe fish. I do have Spanish juv in with Stars & Stripes Puffer juv. no problem with those two. If you can't find info get hold of me and I'll tell you where pictures can be found.
