Micracanthicus vandragti L-280

A Little More Information...

Micracanthicus vandragti L-280, also known as Mitu Dwarf, is a small loricariid from Colombia, associated with the Rio Mitu in the Vaupés basin. Its compact, dark body and contrasting pale spots make it an appealing choice for a carefully planned biotope or peaceful community aquarium. This wild-collected species is considered uncommon to relatively rare in the aquarium trade. It requires warm, soft and well-oxygenated water, along with a mature setup containing grazing surfaces, driftwood, rocks and several sheltered areas.

General species description

Micracanthicus vandragti L-280 is a small suckermouth catfish belonging to the family Loricariidae. It spends much of its time attached to rocks, wood or aquarium glass, especially where current provides oxygen and renews food resources. Its small adult size suits aquariums with a good bottom area, but it should not be treated as a simple algae eater. A mature, stable aquarium rich in biofilm is far more suitable than a newly established tank. The species is generally discreet, with increased activity at dusk and during the night.

Geographic origin and biotope

The species comes from Colombia, in the area of the Rio Mitu, within the Amazonian region of Vaupés. Its habitat is associated with shallow, rocky and well-oxygenated sections bordered by tropical forest. The bottom may include slabs, pebbles, sand and submerged wood. In the aquarium, efficient filtration, gentle to moderate flow and warm, acidic to slightly acidic water provide a closer approximation of its habitat than general community-tank conditions alone.

Precise location and local name

The reference locality is the Rio Mitu, near the city of Mitú in Colombia’s Vaupés Department. The trade name Mitu Dwarf refers directly to its geographic origin and small adult size. The code L-280 is used in the loricariid trade to identify this form or species before and alongside its scientific name. Because its known range is relatively localized, it is best obtained from a supplier who can provide clear information about origin and acclimation conditions.

Appearance and physical characteristics

The body of Micracanthicus vandragti L-280 is short, sturdy and covered with the bony plates typical of Loricariidae. The base colour ranges from very dark brown to black, with small pale markings that create a spotted appearance. Its inferior mouth is adapted for adhesion, allowing it to hold onto surfaces while grazing on biofilm. The fins are proportionate to its small size and may show pale spotting or lighter margins. This combination of small adult size, dark coloration and pale spots explains its appeal among specialist loricariid keepers.

General diet

Micracanthicus vandragti L-280 makes use of biofilm, algae and organic matter found on submerged surfaces. Natural grazing should nevertheless be supplemented with vegetable-based sinking wafers, spirulina foods and occasional small portions of more protein-rich foods. Blanched vegetables such as zucchini may also be offered. Feedings are best provided after the lights go out to reduce competition. A varied, regular diet rich in plant matter helps maintain body condition without unnecessarily loading the water with waste.

In your aquarium

To keep Micracanthicus vandragti L-280 successfully, use a mature, well-filtered aquarium furnished with smooth rocks, roots and small caves. Warm, soft and stable water is essential, as is strong oxygenation. Because this is a wild-collected and relatively uncommon fish, gradual acclimation and careful monitoring of feeding are especially important. Avoid boisterous tankmates and make sure sinking foods reach the bottom after the aquarium lights have been switched off.
