Introduction

Corydoras pastazensis, commonly known as Pastaza Corydoras, is a peaceful and social bottom-dwelling fish native to the Pastaza River Basins in South America. Known for their unique patterns and gentle temperament, they are a favorite among aquarists seeking a community-friendly species that thrives in groups.

Food and Feeding

Pastaza Corydoras are not picky eaters, making them easy to care for. Provide a staple diet of high-quality flake or sinking pellets, supplemented with algae wafers. Twice a week, treat them to live or frozen foods such as bloodworms or brine shrimp. As they are most active during the evening, feeding them at this time ensures they receive their fair share.

Habitat and Tank Requirements

To recreate their natural environment, use a sandy substrate to protect their sensitive barbels. Incorporate plenty of hiding spots with driftwood, smooth rocks, and plants to create a comfortable and secure habitat. Suitable plants include Amazon Sword (Echinodorus bleheri), Java Fern (Microsorum pteropus), and Cryptocoryne species (Cryptocoryne wendtii). Maintain water parameters with a pH of 6.2-7.2, hardness of 3-16°N (53.57-285.71 ppm), and a temperature range of 21-27°C (69.8-80.6°F). Ensure good water quality with regular water changes and proper filtration.

Sexing

Females are slightly larger and have a stockier body shape compared to males, which can be observed when viewed from above. This distinction becomes more noticeable during the breeding season.

Breeding

Currently, there are no reported cases of Corydoras pastazensis breeding in captivity. In the wild, they are egg scatterers, depositing eggs among plants or substrate. Replicating these conditions with a breeding setup might encourage spawning behaviors, but more research is needed for successful reproduction in aquariums.

Lifespan

The typical lifespan of Pastaza Corydoras is 3-5 years with proper care and a stable environment.

Behavior and Compatibility

Pastaza Corydoras are social fish that should be kept in groups of at least five. Their peaceful nature makes them excellent tank mates for other non-aggressive species such as Neon Tetras (Paracheirodon innesi), Ember Tetras (Hyphessobrycon amandae), and Harlequin Rasboras (Trigonostigma heteromorpha). Avoid keeping them with boisterous or aggressive species, as this can cause stress and lead them to become shy and inactive.

Short Description

Corydoras pastazensis, or Pastaza Corydoras, is a peaceful bottom-dweller that thrives in groups. Their preference for sandy substrates and planted tanks makes them ideal for aquariums that mimic natural biotopes. Avoid housing them with overly active species, and provide a clean, well-maintained environment for optimal health and longevity.
