I've seen them in books as a Splitlevel Hogfish, and a quick Google search on them revealed they're in the wrasse family, get to about 25 cm.
Morphology: Juveniles and adults resemble their counterparts of B. axillaris, but juveniles have yellow rather than white spots and adults have well-defined black band between the light and dark portions of the body and lack ocelli on the dorsal and anal fins.
Biology: Inhabits coral-rich outer reef slopes at depths of 5 to over 20 m, particularly near caves. Juveniles in caves; adults swim openly about, but usually close to the substrate, and often engage in cleaning larger fishes
Apart from books, have never seen one in a LFS, but my Google search revealed a few online places you can get one for about $20.
Revealed some cool pics too:
