Food and Feeding

Acre Corydoras (Corydoras acrensis) are omnivores and thrive on a balanced diet of both plant and animal matter. Their staple diet should include high-quality flakes and algae wafers. To ensure optimal health and coloration, it is recommended to offer supplemental treats twice a week, such as brine shrimp or bloodworms. These fish are most active during the evening hours, so it’s best to feed them at dusk to align with their natural feeding schedule.

Origin

Acre Corydoras are native to the freshwater rivers and streams of South America, particularly in Brazil. These fish are accustomed to soft, slightly acidic to neutral waters and thrive in environments that replicate their natural habitat, which is rich in vegetation and features sandy or muddy substrates.

Sexing

Distinguishing between male and female Acre Corydoras is easier when they are viewed from above. Females tend to be slightly larger and have a broader, stockier body shape, especially when carrying eggs. Males are typically slimmer and more streamlined in appearance.

Breeding

Breeding Acre Corydoras in captivity is rare, but they are egg scatterers like other Corydoras species. In the wild, they deposit their eggs in well-hidden areas among dense vegetation or within crevices. To encourage breeding in an aquarium setting, simulate rainy season conditions by performing a partial water change with cooler, softer water, and provide plenty of hiding spots. If successful, be sure to separate the adults after spawning to prevent them from consuming the eggs.

Lifespan

With proper care, Acre Corydoras can live for 3 to 5 years. Maintaining a clean, well-balanced aquarium environment with stable water parameters will help ensure they reach their full lifespan. Regular water changes and a varied diet are essential for their longevity.

Tank Setup and Environment

Acre Corydoras are bottom-dwelling fish and prefer aquariums that mimic their natural habitat. A tank of at least 40 liters (10 gallons) is recommended for a small group. These fish are peaceful and should be kept in groups of at least 6 to promote their social behavior. A sandy or fine gravel substrate is crucial to protect their sensitive barbels, and the tank should include plenty of plants, driftwood, and smooth rocks to create hiding spots. Aim to keep the water temperature between 21-25°C (69.8-77°F) with a pH range of 6.4-7.4 and moderate water hardness (2-21°N or 35.71-375 ppm).

Compatibility and Tank Mates

Acre Corydoras are peaceful fish, making them excellent additions to community tanks. Suitable tank mates include other small, non-aggressive species such as Harlequin Rasboras, Guppies, and Neon Tetras. Avoid housing them with aggressive or boisterous fish, as this can cause unnecessary stress. Always maintain a peaceful environment to keep Acre Corydoras thriving.

Short Description

The Acre Corydoras (Corydoras acrensis) is a small, peaceful catfish native to the rivers of South America. These bottom-dwellers are ideal for community tanks and should always be kept in groups of at least 6. They prefer soft substrates like sand or fine gravel to protect their barbels and need plenty of hiding spots such as driftwood and plants. With a lifespan of 3 to 5 years, they are hardy but require stable water conditions and a varied diet to thrive.
