What kind of fish are these?

Yep- those orange spotted filefish are notorious obligate corralivores- only acro polyps. Other file fish eat many things, but this species is destined for death in almost every aquarium. Atlantis Marine world put a pair in their 20,000 gallon reef to add to it, and the pair is supposed limiting growth of the acros to minimize pruning.
