Longfin Lemon Bristlenose Plecos

Meet the Longfin Lemon Bristlenose Pleco (Ancistrus sp.)
Vibrant. Peaceful. Built for Beauty and Function.

Add a splash of sunshine to your freshwater aquarium with the Longfin Lemon Bristlenose Pleco—a rare and eye-catching variety of the beloved bristlenose catfish. Known for their gentle nature, algae-eating abilities, and stunning long flowing fins, these fish are a perfect combination of elegance and utility.

Appearance:
This variant features a brilliant lemon-yellow body, often with subtle marbling, and long, veil-like fins that ripple beautifully in the water. Males display soft bristles on their nose, which give the species its name and add to its unique charm.

Size:
Unlike common plecos, Longfin Lemons stay manageable—adults typically reach 4 to 6 inches, making them ideal for medium-sized tanks.

Behavior:
These plecos are peaceful, shy bottom-dwellers that get along well with most community fish. They’re nocturnal, often emerging at dusk or when the lights are dimmed to graze on algae and leftover food.

Diet:
Primarily herbivorous, they thrive on a diet of algae wafers, spirulina-based pellets, blanched veggies (like zucchini or spinach), and occasional protein treats like bloodworms. Regular grazing keeps your tank clean and their digestive systems healthy.

Lifespan:
With proper care, they can live up to 10 years—a long-lasting and rewarding addition to any aquarium.

Tank Requirements:

• Tank size: 20 gallons or more
• Water temp: 72–82°F
• pH: 6.5–7.5
• Provide driftwood, caves, or PVC hiding spots to mimic their natural habitat
• Gentle water flow preferred

Breeder’s Bonus: Longfin Lemons can be bred in captivity with the right conditions. Males will guard eggs in a cave or tube, offering an exciting breeding project for hobbyists.

Whether you're a seasoned aquarist or just starting out, the Longfin Lemon Bristlenose Pleco is a hardy, low-maintenance, and visually striking species that pulls double-duty as both a tank cleaner and conversation piece.
