Corydoras Sp.

Datasheet

General Description

This unidentified species, commonly known as Corydoras Sp., is part of the Callichthyidae family and believed to represent C115 and C116 trading numbers. Showing remarkable variability in color patterns, these catfish are known for their adaptability and are facultative air breathers. They are characterized by their bony plates instead of scales, defining them as part of the "armoured" catfish group.

Aquarium Setup

For optimal care of Corydoras Sp., it is recommended to maintain them in groups of at least 6-8 individuals. Utilizing fine sand or clean rounded gravel substrates is advisable. Providing suitable decorations and hiding spots is essential to ensure the fish's security within the aquarium. Water conditions should be closely monitored and maintained within specific parameters (see table).

Behaviour

Corydoras Sp. are peaceful and social fish that thrive in group settings. Occasionally, they surface to gulp air due to their specialized intestinal structure for atmospheric oxygen absorption. Care must be taken when handling them, as their stiff pectoral-fin spines can cause painful wounds.

Feeding and Diet

These foraging omnivores accept various sinking dried and live foods, ensuring a diverse diet promotes their optimal health. It is crucial not to rely solely on leftovers from other tank inhabitants for their sustenance.

Reproduction & Dimorphism

Females of Corydoras Sp. tend to be larger and rounder than males, particularly when gravid. Their breeding behavior involves egg-scattering, usually on broad-leaved plants or flat surfaces.

Habitat and Distribution

Corydoras Sp. is found in the upper Río Madre de Dios in the Madre de Dios region of southern Peru, stretching from the Manú National Park to Puerto Maldonado downstream. Notably, a substantial portion of their habitat lies in Bolivia, where they eventually join the Río Beni to form the Río Madeira, a major tributary of the Amazon River.

Etymology

The genus name Corydoras is derived from the Ancient Greek words "korus" meaning "helmet" and "dora" meaning "skin, hide of an animal," reflecting the bony plates found on these fish.
