Description
The Mexican Nightsergeant is a hardy and territorial damselfish native to the Eastern Pacific, particularly the Gulf of California. It displays a light body with several distinct dark vertical bands, which can vary in intensity. This species is known for its robust nature but requires careful tankmate selection due to its assertive temperament.
