The bandit angel is endemic to the Hawaiian Islands, Johnston and Midway Atoll. It can be found single or in pairs inhabiting rocky reef faces and slopes at depths between 60 and 400 feet.
If you contact local divers they'll catch them, some will acclimate them, and then ship them to you. The problem with them is that anything smaller then 3"-4" are all very deep. Only the adults come up closer. Singles I have found for $400.
That's the smallest one I've ever seen!!! There is a guy I've been talking to that said he can get 4"-5" for $300!! One that size I think he said $600. Awesome catch.
