Pseudorinelepis sp. L-152 "Rio Apure"

A Little More Information...

Pseudorinelepis sp. L-152 "Rio Apure", also known as Pineapple Pleco, is a rare loricariid traded under the aquarium code L-152. Its armored appearance, broad body and strongly textured plates give it a distinctive look among plecos. Associated with the Rio Apure, this fish comes from the Orinoco basin and remains a sought-after specimen among specialized aquarists. Available specimens are wild-collected, so they require careful acclimation, well-oxygenated water and a mature aquarium. Its rarity, rated very rare, makes long-term conservation and attentive husbandry especially important.

General description

Pseudorinelepis sp. L-152 "Rio Apure" is an armored catfish from the family Loricariidae, recognized in the aquarium trade under the L-152 code. It belongs to the group of large, robust-bodied plecos that are better suited to spacious aquariums with strong filtration. Its behavior is mainly crepuscular and nocturnal: it rests on the décor during the day, then explores the bottom and available surfaces for food. Like many loricariids, it has a sucker mouth and protective bony plates. Its limited availability and wild origin make it better suited to experienced aquarists who can maintain stable, well-oxygenated water.

Geographic origin and biotope

The L-152 “Rio Apure” code refers to the Rio Apure, a major waterway of the Orinoco basin in Venezuela. The associated biotope includes tropical waters with calm to moderately flowing areas, wooded banks, submerged branches and accumulations of plant debris. In the aquarium, this origin points to the need for good oxygenation, regular circulation and shelters where the fish can withdraw. Clean water with low organic waste and no rapid changes is particularly suitable for a specimen collected from the wild.

Precise location and local name

The trade designation “Rio Apure” places this form in the Orinoco basin of Venezuela. L-152 is a code used by aquarists and importers to identify this form, which is not given a specific species name in the trade name. A field vernacular name is not included here; in the aquarium trade, the most common names are Pineapple Pleco, Pineapple L-number and Pseudorinelepis L-152. The abbreviation “sp.” indicates that the fish is presented as a form within the genus rather than as a formally named species under this commercial designation.

Appearance and physical characteristics

The body of Pseudorinelepis sp. L-152 "Rio Apure" is broad, flattened and covered with clearly visible bony plates. Its general coloration ranges from olive brown to grayish brown, with a mottled or irregular pattern that helps it blend with wood and sediment. Its lower sucker mouth allows it to cling to surfaces and graze on food deposits. The strongly textured armor explains the common name Pineapple Pleco, which refers to the rough surface of a pineapple. The aquarium should be arranged without sharp edges, since its fins and plates may become caught in poorly designed décor.

General diet

Pseudorinelepis sp. L-152 "Rio Apure" benefits from a varied diet with a mainly plant-based component supplemented by protein sources. Offer sinking foods for bottom fish, algae-based foods and vegetables such as zucchini, cucumber or squash. Meals should preferably be provided after the lights go out, when its activity increases. The presence of natural wood in the aquarium provides grazing surfaces and shelter, but does not replace a complete diet. For a wild-collected fish, regular feeding and access to food that sinks quickly are essential to prevent competition with midwater fish.

In your aquarium

Success with Pseudorinelepis sp. L-152 "Rio Apure" begins with a mature, spacious aquarium equipped with efficient filtration. Provide several shelters made from wood or smooth rock, moderate lighting and food that actually reaches the bottom. Regular water changes, stable temperature and strong oxygenation are especially important for a fish collected from the wild. Avoid excessive feeding competition and monitor its body condition, particularly during the first few weeks. Because it is a very rare fish, responsible aquarium keeping should prioritize longevity rather than rapid growth or improvised breeding attempts.
