About
Ancistrus dolichopterus (L183) hails from the dark, acidic waters of the Rio Negro in Brazil. Its jet-black body is covered in small white spots and edged with white fin margins, creating a dramatic starlight effect. It requires soft, acidic water to thrive and is an excellent grazer in well-planted blackwater biotopes.
Care Guide

Feeding: Herbivore; algae wafers, driftwood grazing, blanched greens, spirulina. Behaviour: Nocturnal; males guard eggs in caves — provide one cave per male.
