Natural habitat

The hastatus cory is native to Brazil and Paraguay, found in shallow, slow-moving streams and floodplain habitats across the Amazon and Paraguay river basins. They typically inhabit areas with soft sand or fine silt substrates covered in decomposing leaf litter and dense vegetation, providing them with cover from predators.

Where they are found

The natural habitat of Corydoras hastatus is characterized by warm, slow-moving waters rich in biodiversity. This species prefers slightly acidic to neutral pH levels in environments where organic debris is present, creating an ideal environment for their foraging habits.

Aquarium care

Corydoras catfish thrive in a well-maintained aquarium with soft, smooth substrate to protect their barbels. Regular water changes and tank mates that will not disturb them are essential for a healthy environment.

Feeding

Hastatus corys require small, finely crushed foods such as high-quality flakes or micro pellets. Frozen foods like baby brine shrimp and daphnia provide excellent nutrition. They also naturally graze on biofilm and require frequent, small feedings throughout the day to meet their dietary needs.

Compatibility

Corydoras are highly social fish that do best in groups of six or more. They can be housed with most community fish that are peaceful and not large enough to eat them. Avoid pairing them with aggressive species or those that compete heavily for food.

Breeding

Breeding Corydoras hastatus requires a separate breeding tank with a fine substrate. The courtship ritual involves males chasing females, leading to the laying of eggs which should be removed promptly after spawning to prevent predation. The eggs usually hatch within 5-7 days under optimal conditions.
