Introduction

The Peckoltia sp. L-387, also known as Orange Tiger, is a South American armored catfish valued for its contrasting pattern and discreet habits. Listed under an L-number, this fish is treated as an undescribed species within the genus Peckoltia. Native to Colombia and collected from the wild, it is best suited to aquarists who enjoy bottom-dwelling fish and carefully planned Amazonian-style habitats. Its availability is generally uncommon, making it an appealing find for a regional or peaceful community aquarium.

General species description

Peckoltia sp. L-387 is a small armored catfish in the family Loricariidae. Like many Peckoltia, it remains close to the bottom, especially during the day, and becomes more active as the aquarium lights dim. Its appeal comes from its orange-brown and black pattern, as well as its ability to live in a peaceful community aquarium. It should nevertheless be considered uncommon and better suited to experienced aquarists, since wild specimens require careful acclimation and stable water conditions.

Geographic origin and biotope

This form is associated with Colombia and freshwater habitats in northwestern South America. It likely inhabits stream sections with stones, gravel and submerged wood, together with shaded areas that support its nocturnal lifestyle. In the aquarium, provide an environment rich in hiding places, roots and grazing surfaces. Moderate current, strong oxygenation and efficient filtration are preferable to stagnant water.

Precise location and local name

The most widely used aquarium name is Orange Tiger. The L-387 number is used by aquarists to identify this form when it is traded before a possible scientific description. The designation Peckoltia sp. indicates that the fish is retained within the genus without being assigned to a formally named species. A precise collection locality is not included here; the country of origin associated with this population is Colombia.

Appearance and physical characteristics

The body is sturdy and flattened underneath, with protection from bony plates. Its lower mouth forms a sucker-like disk suited to attachment and grazing. The typical pattern combines orange to golden-brown tones with darker bands or markings, explaining the Orange Tiger name. The fins usually carry a matching pattern. Adult size remains moderate, but the fish needs a layout with several shelters because it is territorial around its hiding places.

General diet

Peckoltia sp. L-387 is an omnivore with a detritivorous tendency, grazing surfaces for biofilm, algae and small organisms. Its diet should include sinking wafers for bottom fish, vegetable-based foods and blanched vegetables such as zucchini. Occasional protein-rich foods can supplement the diet, particularly after the lights go out. Natural wood is useful in the layout and can support grazing behaviour, but it never replaces a complete and regular feeding program.

In your aquarium

To keep Peckoltia sp. L-387 successfully, use a mature, well-filtered aquarium with plenty of hiding places made from wood or rock. Stable water, strong oxygenation and evening feeding are essential. Because this is a wild-collected and uncommon fish, acclimation should be gradual and followed by close observation. Avoid excessive competition for food among bottom-dwelling fish.
