Hoplisoma loxozonum

About This Species

Basic Description

The Slant-bar Corydoras is a peaceful bottom-dweller, easily recognized by the bold black stripe running diagonally down its body. These are social catfish that must be kept in groups to feel secure and exhibit natural behaviors. They are excellent tank cleaners, constantly sifting through the substrate for leftover food. Their small size and calm temperament make them a wonderful addition to most community freshwater tanks, where they patrol the bottom zone. They are quite hardy but appreciate stable water conditions and a well-maintained environment.

Detailed Description

Originating from South America's slow-moving waters, Hoplisoma loxozonum requires gentle flow in the aquarium to mimic its natural habitat. Keeping them in shoals is essential for their security and encourages natural foraging. A varied omnivorous diet is crucial; supplement standard sinking pellets with protein-rich live or frozen foods to ensure optimal health. To protect their sensitive barbels, a soft sand substrate is highly recommended, as they constantly sift through it for food; this rooting behavior also helps aerate the substrate. Breeding can be induced with large, slightly cooler water changes, simulating seasonal rainfall.

Scientific Description

Hoplisoma loxozonum, of the family Callichthyidae, is a benthic siluriform recently reclassified from the genus Corydoras. Its physiology is adapted to its native South American habitats, featuring a low metabolic rate and the capacity for accessory intestinal respiration, allowing it to utilize atmospheric oxygen. As an omnivorous detritivore, its foraging behavior involves significant bioturbation of the substrate, impacting local nutrient cycling. The species is characterized by a low bioload factor, reflecting a minimal contribution to nitrogenous waste accumulation relative to its biomass, a key consideration for stocking density calculations in controlled environments.
