L183 Starlight AKA White Seam Bristlenose Pleco (Ancistrus dolichopterus) - Tank Bred

 

Species Overview

The L183 Starlight Bristlenose Pleco, also known as the White Seam Bristlenose Pleco, is one of the most sought-after members of the Ancistrus genus. This beautiful pleco is instantly recognizable by its jet-black body covered in brilliant white spots and the striking white edging that develops along the dorsal and caudal fins. These distinctive "white seams" become especially pronounced in healthy juvenile and subadult fish, making the L183 one of the most visually impressive bristlenose plecos available.

Unlike many larger pleco species, the L183 Starlight Bristlenose Pleco remains a manageable size while providing all the personality and algae-grazing behavior that aquarists love. Tank-bred specimens adapt readily to aquarium life, becoming active members of peaceful community aquariums where they spend their days grazing on driftwood, rocks, aquarium glass, and other hard surfaces. Their peaceful temperament, striking appearance, and fascinating behavior make them a favorite among planted aquarium enthusiasts and pleco collectors alike.

Swimming Zone

L183 Starlight Bristlenose Plecos spend nearly all of their time along the bottom of the aquarium and across hard surfaces. They regularly graze on driftwood, rocks, broad plant leaves, and aquarium glass while searching for algae, biofilm, and other naturally occurring food sources. During daylight hours they often rest beneath driftwood or inside caves before becoming increasingly active during the evening.
