Remarks: Not rare in the wild but their collection range is restricted to the Marshall Islands, which at one point only produced a few fish for import. Recently their number has bumped up allowing prices to come down a bit. Similar demeanor to the other firefish and just as hardy if properly handled during transport. Dorsal part of the body can darken under intense lighting.
