Right family, wrong genus, because it is an uncommon fish here is a hint, it is from new Guinea, New Caladonia, and Northeasren Australia.
A site I usually start my searches in is www.fishbase.org, they are about as close as you can get to a complete data base. You can search by common name, genus/species, jfamily, etc, and they even have identification guides.

That would be Rhinopias aphanes, Merlet's scorpionfish. They had several of these at the Aquarium of the Pacific. Totally freaked my wife out as she had no clue that they were fish until one of them moved.
