Ancistrus martini, commonly known as the Martini bristlenose catfish, is a small freshwater catfish native to South American river systems. It grows to about 8.9 cm (3.5 in) and is a nocturnal, algae‑grazing bottom dweller that is more prized by aquarium hobbyists than sport anglers. Its modest size and shy nature make it a light‑tackle target for anglers seeking a unique tropical catfish experience.
