The Otocinclus Flexilis - Otocinclus Catfish (Medium) is a spectacular centerpiece for the modern community aquarium, known for its brilliant coloration and sophisticated social behavior. Characterized by a sleek, mottled silver-and-brown body and a specialized sucker-mouth designed for precision grazing, this Medium variant is a masterclass in aquatic aesthetics. In the "Answering Machine" era of specialized cleanup crew husbandry, the Otocinclus is highly prized for its unmatched efficiency in managing soft algae and its ability to cohabit peacefully with even the most delicate shrimp and nano-fish.
Unlike many larger algae-eaters that outgrow their welcome, the Medium Otocinclus remains compact and dedicated to its role. They are exceptionally active swimmers that occupy the lower and middle levels of the water column, providing a constant display of color and rhythmic, scavenging movement across glass and leaf surfaces.
Note: Images shown are stock images and not the actual fish you will receive.
Care Level: Easy to Moderate
Temperament: Peaceful
Variant Size: Medium
Minimum Tank Size: 10 Gallons
Diet: Herbivore (Algae-based)
Reef Compatible: N/A (Freshwater)
Max Size: 2 Inches
Temperature: 72° to 82°F
dKH: 3 to 10
pH: 6.0 to 7.5
The Medium Otocinclus Catfish is an ideal candidate for a community planted tank. While they are famously efficient at cleaning glass, they require a mature system with established biofilm and supplemental feedings of algae wafers or blanched vegetables to thrive. They are high-metabolism grazers and should be fed a varied diet of high-quality sinking greens at least once daily. Because they are highly social, keeping them in groups of six or more is mandatory to ensure they feel secure and display their most natural, active schooling behavior.
We’ve dialed in the logistics for national Overnight Delivery to ensure your livestock arrives in peak condition. Every order is packed using professional-grade insulation and climate-contingent heat or ice packs, designed to maintain stable temperatures throughout the journey. We handle the technical side of the move so you can focus on the acclimation. Our protocol is built on getting these fish from the facility to your tank with zero compromise on health or vitality.
