Undulated trigger

The Undulated Triggerfish (Balistapus undulatus) is a vibrantly colored marine fish primarily found in the Indo-Pacific region. It is characterized by its deep green body with striking orange to yellow lines or undulations, making it quite distinctive. Typically, it has a robust body shape common to triggerfish, with a strong jaw and a signature dorsal spine mechanism used for defense. This species is moderately well-known in the aquarium hobby, but its aggressive nature can make it challenging to keep with other fish.
