I have a few other pics of the male that are a bit closer. I'll try to find them this afternoon. I've been stuck with the Coolpix camera until I fix my good one... haven't been taking as many photos.
My LFS got a handful in about a year ago. I thought they were Buffalo Heads but when he told me what they were I was very interested. I like to stick with Tangs and wanted something similar to a goby or other fish lacking a swim bladder. They're not the prettiest fish but they make up for it in personality. I love watching them hop around the tank. So far they've mixed just fine with my existing stock... better than Julies or Cylindricus ever did.
There's been plenty of breeding behavior... I"ll keep you informed if I get any fry out of them.
