The Bursa Trigger, Rhinecanthus verrucosus, also known as the Black Patch Trigger, Blackbelly Trigger, or Bursa Triggerfish, features a half white and half yellow face with a pencil-thin moustache and colorful mask over its eyes. It would certainly be one of the most strikingly beautiful fish in your aquarium. They can make an audible grunting sound. The Bursa Trigger eats a varied carnivorous diet of squid, krill, fish, clam, and shrimp. They should not be kept with predatory fishes, or other triggers. It is hardy and easy to care for.
