The L144 Blue Eye Bristlenose Longfin Pleco, also known as the Blue Eye Bristlenose Pleco or simply the L144 Pleco, is a variant of the common Bristlenose Pleco (Ancistrus sp.) with long fins and blue eyes. Here are some key points about this pleco variant:

- Appearance: The L144 Blue Eye Bristlenose Longfin Pleco has a similar appearance to the common Bristlenose Pleco but with long, flowing fins. They have a stout and elongated body covered in small bony plates. The coloration can vary but typically includes a dark base color (often black or dark brown) with lighter or yellowish spots or marbling patterns. The distinguishing feature of this variant is the bright blue eyes, which add an eye-catching element to their appearance.

- Size: The L144 Blue Eye Bristlenose Longfin Pleco can grow up to around 4-6 inches (10-15 cm) in length, making them suitable for medium-sized aquariums.

- Habitat and Origin: Bristlenose Plecos are native to South America, specifically the rivers and streams of the Amazon basin. They inhabit areas with slow to moderate water flow and prefer rocky or driftwood-filled environments.

- Tank Requirements: To provide the best care for L144 Blue Eye Bristlenose Longfin Plecos, a tank with a minimum size of 20 gallons (75 liters) is recommended. They appreciate plenty of hiding spots, such as caves, driftwood, and rocks, to mimic their natural habitat. Dense vegetation can also be added to the tank. The substrate should be sandy or fine gravel to avoid damaging their delicate long fins. Adequate filtration and regular water changes are important for maintaining good water quality.

- Water Conditions: These plecos prefer water conditions that resemble their native habitat. The ideal temperature range is around 72-82°F (22-28°C), and the pH should be slightly acidic to neutral, ranging from 6.0 to 7.5. They can tolerate a range of water hardness levels, but it's best to aim for moderately soft to slightly hard water.

- Diet: L144 Blue Eye Bristlenose Longfin Plecos are primarily herbivorous and require a diet rich in plant matter. They will readily consume algae, vegetable-based sinking pellets or wafers, blanched vegetables (such as zucchini or cucumber), and occasional live or frozen foods like bloodworms or brine shrimp.

- Behavior and Compatibility: Bristlenose Plecos, including the L144 variant, are generally peaceful and can be kept in community aquariums with other non-aggressive fish species. However, they can become territorial toward their own kind, so it's recommended to provide ample hiding places and space for multiple plecos if keeping them together. They are primarily bottom-dwelling fish and spend much of their time grazing on algae or searching for food on the substrate.

- Breeding: Breeding Bristlenose Plecos can be achieved in the aquarium with the right conditions. They are egg layers and will lay their eggs on various surfaces, such as rocks or driftwood. Providing suitable spawning sites, such as caves or flat surfaces, can encourage breeding behavior. The male will guard the eggs until they hatch, and the fry can be fed with specialized fry foods or finely crushed flakes or pellets.

The L144 Blue Eye Bristlenose Longfin Pleco is a visually striking pleco variant that can add a unique touch to your aquarium. With their long fins, blue eyes, and active behavior, they are an attractive and interesting addition to a well-maintained aquarium.
