L128 Blue Phantom Pleco

L128 Blue Phantom Pleco (Hemiancistrus sp.128)

The L128 Blue Phantom Pleco is a highly sought-after freshwater catfish, admired for its deep blue-gray coloration, subtle golden spotting, and striking armored appearance. Native to the fast-flowing rivers and rocky waterways of the upper Orinoco River basin in Venezuela, this beautiful pleco is prized by aquarists for its unique appearance, peaceful nature, and ability to thrive in carefully maintained planted and river-style aquariums. Its elegant coloration and fascinating behavior make it a true centerpiece among ornamental plecos.

Blue Phantom Plecos are peaceful, nocturnal fish that spend much of their time exploring caves, rocks, and driftwood throughout the aquarium. During the day, they often rest in sheltered areas, becoming more active in the evening and nighttime hours as they forage and investigate their surroundings. Although generally peaceful with other fish, they can become mildly territorial toward other bottom-dwelling species, especially when competing for preferred hiding spots.

These beautiful plecos thrive in aquariums designed to replicate their natural river habitat, with strong oxygenation, excellent water quality, smooth rocks, driftwood, and plenty of caves for shelter. Moderate to strong water flow helps recreate the fast-moving waters they originate from while encouraging natural behaviors. Unlike many common plecos, Blue Phantom Plecos are not heavy wood eaters and require a balanced diet of high-quality sinking pellets, algae wafers, spirulina-based foods, fresh vegetables, and occasional frozen foods such as bloodworms and brine shrimp to maintain their health and coloration.
