Hoplo Port Catfish - Hoplosternum Thoracatum

The Hoplo Port Catfish, scientifically known as Hoplosternum thoracatum, is a hardy, peaceful bottom-dweller prized for its active personality and unique armored appearance. Its body is covered in bony plates rather than traditional scales, giving it a rugged, prehistoric look, while its long barbels are constantly in motion as it scavenges the substrate. Coloration is typically a mottled mix of browns and tans, allowing it to blend naturally into sandy or planted aquariums.

Unlike many shy catfish, Hoplos are surprisingly outgoing and often visible during the day, especially once settled. They are social by nature and do best in groups, where you’ll often see them interacting, foraging together, and even darting to the surface for gulps of air—this species can breathe atmospheric oxygen, making it very adaptable to a range of conditions. Their energetic behavior and constant activity make them a great addition to larger community tanks with other peaceful species.

A soft substrate like sand is strongly recommended to protect their sensitive barbels, along with driftwood and plants to create a natural environment. While very tolerant, they thrive in clean, well-oxygenated water with stable parameters. They are excellent scavengers but should not be relied on as “cleaner fish”—they require a proper, varied diet to stay healthy.
