Food and Feeding

The Fairy Cory is not a picky eater, but for optimal health, offer a balanced diet of catfish pellets, algae wafers, and high-quality flake food. They thrive on occasional protein-rich treats like bloodworms and brine shrimp. Incorporating live or frozen foods into their diet once or twice a week can enhance their color and vitality. Always ensure food reaches the bottom of the tank to accommodate their natural feeding habits.

Origin

Native to the freshwater streams of South America, Fairy Cories are predominantly found in the Rio Tigre and Rio Conambo river systems in Ecuador. These regions offer clear waters with sandy substrates and dense aquatic vegetation, providing an ideal environment for these peaceful fish. Their natural habitat is often shaded with minimal light, so replicating this in the aquarium will make them feel more at home.

Sexing

Sexing Fairy Cories can be challenging, but a noticeable difference is in body size and shape. Females are typically larger and more robust, especially when viewed from above. Males, on the other hand, are more slender. During the breeding season, these differences become more pronounced, with females appearing fuller due to egg development.

Breeding

Breeding Fairy Cories in captivity is relatively straightforward with the right conditions. Regular large water changes using cooler water (a few degrees below tank temperature) can trigger spawning behavior. Once the eggs are laid, they will be scattered throughout the tank, including on plants and the glass. To ensure higher fry survival rates, it is recommended to remove the parents, as they may eat the eggs. The eggs will typically hatch within 4 days, and after another couple of days, the fry will become free-swimming. Feed the fry crushed flake food or powdered fry food, and supplement with newly hatched brine shrimp as they grow.

Lifespan

Under proper care and with stable water conditions, Corydoras atropersonatus can live for 3 to 5 years in the aquarium. Ensuring high water quality and a nutritious diet can help extend their lifespan.

Short Description

Fairy Cories are a peaceful, shoaling species that should always be kept in groups of at least 5 or more to prevent stress and promote natural behaviors. They are an excellent choice for community tanks but should not be housed with aggressive or fin-nipping species. To avoid damage to their sensitive barbels, provide a soft substrate such as sand or fine gravel. These fish are active bottom dwellers and enjoy hiding spots, so adding driftwood, rocks, or plants will create a safe and stimulating environment for them.
