Dekeyseria picta L-052

A Little More Information...

Dekeyseria picta L-052 is a small Amazonian loricariid also known as the Atabapo Butterfly. Native to the Rio Atabapo in Colombia, this pleco is recognized by its flattened body and dark pattern resembling butterfly wings. It is a peaceful bottom-dwelling fish that does best in a well-oxygenated aquarium with surfaces to graze and retreats for shelter. This wild-collected species remains reasonably available through specialty aquarium retailers, although it is less consistently seen than several popular plecos. Its discreet behavior and preference for soft, acidic water make it an appealing choice for a carefully arranged Amazonian aquarium.

General species description

Dekeyseria picta L-052 is a small pleco in the genus Dekeyseria, belonging to the family Loricariidae. It spends much of its time resting on rocks, wood, or other surfaces, where its flattened shape helps it cope with current. Activity often increases as the aquarium lights dim. Generally peaceful, it is suitable for a community aquarium containing calm fish. It should nevertheless be provided with stable, clean, well-oxygenated water and several hiding places. Availability is usually good through specialty retailers, although it is not as consistently offered as the most common captive-bred species.

Geographic origin and habitat

The species comes from the Rio Atabapo in Colombia, within the Orinoco drainage. It inhabits clear to slightly tea-colored water with noticeable current and good oxygen levels. The natural setting includes rocky outcrops, submerged wood, and shaded areas created by plants along the banks. In an aquarium, effective circulation, mature biological filtration, and soft to slightly acidic water recreate its conditions more effectively than stagnant water. Because this is a wild-collected fish, acclimation should be gradual, with particular attention given to water quality and food acceptance.

Precise location and local name

The reference locality is the Rio Atabapo, a river associated with the border region between Colombia and Venezuela. In the aquarium trade, the English name Atabapo Butterfly is widely used because of its contrasting pattern and geographic origin. The L-052 code helps identify it among loricariids in the trade when fish are offered before, or outside of, a detailed taxonomic identification.

Appearance and physical characteristics

The body of Dekeyseria picta L-052 is low, flattened, and covered with bony plates, with a broad head and an underside mouth adapted for grazing. Its background color ranges from grayish brown to yellowish brown and is crossed by dark, irregular, contrasting markings typical of butterfly plecos. The fins are well developed, and the fish readily rests against hard surfaces in the aquarium. Adult size remains modest, at around 12 cm, allowing it to be kept in a reasonably sized aquarium when adequate floor space and shelter are provided.

General diet

Dekeyseria picta L-052 is primarily a grazer with an omnivorous tendency. Its diet should include sinking foods for bottom fish, vegetables such as zucchini or cucumber, and occasional more protein-rich offerings. Natural wood is useful in the aquarium and supports its feeding behavior, but it does not replace a complete diet. Offering food after the lights have partially dimmed is often effective because the fish becomes more active at that time. A varied diet rich in plant matter and offered regularly helps prevent weight loss in recently acclimated specimens.

In your aquarium

To keep Dekeyseria picta L-052 successfully, provide a mature aquarium, efficient filtration, and well-oxygenated circulation. Arrange rocks, wood, and retreats so it can feed and hide during the day. Stable, soft, slightly acidic water, regular vegetable-based meals, and slow acclimation are the most important factors. Since the specimens are wild-collected, avoid sudden changes and monitor food acceptance carefully during the first few weeks.
