ℹ️ Overview

The Rectangular triggerfish (Rhinecanthus rectangulus), also known as the Wedge-tail triggerfish or Humuhumunukunukuapua'a, showcases a distinctive appearance with a primarily gray body marked by a series of vivid lines and geometric shapes, including rectangles. Originating from the Indo-Pacific Ocean, it's recognizable by its compressed body, strong jaw, and dorsal fin capable of locking in place as a defense mechanism. This species is moderately popular in the aquarium hobby, appreciated for its striking colors and interesting behavior, but it requires a spacious tank and careful species selection due to its potential aggressiveness.
