It seems to be an Ogcocephalid, also known as "batfishes". I am no expert though (I am more used to work on bats than on fishes!) so I won't narrow it down :)
it indeed looks like a batfish. From the color of the lips and the the darker patches on the skin it looks to me like a red-lipped batfish (http://www.fishbase.se/summary/Ogcocephalus-darwini.html).
