Scientific name : Balistapus undulatus
Family : Balistidae
Size : Up to 30 cm
Distribution : Red Sea, Indian Ocean, West Tropical Pacific
Biology : These triggerfishes live alone or in small groups near the coral reef where they eat coral, sponges, crustaceans, sea urchins, worms, and fishes. They can dig by blowing a water jet on the sand to find their buried preys.
They are rather lonely, but they can also meet in small groups. Like most triggerfishes, they are very territorial and always hide in the same coral reef to spend to the night.
