Food and Feeding

Reticulated Corydoras are bottom-dwelling omnivores that thrive on a balanced diet. Their staple food should include high-quality sinking pellets or flakes, supplemented with algae wafers. To enhance their health and coloration, offer treats like bloodworms or brine shrimp twice a week. These fish are most active during the evening, so feeding them at this time ensures they receive their fair share of food in community tanks.

Origin

Native to the lower Amazonian River Basins of Brazil, Reticulated Corydoras inhabit slow-moving freshwater streams and rivers. These habitats are often characterized by sandy substrates, dense vegetation, and soft, slightly acidic to neutral water. The intricate network-like pattern on their bodies helps them blend into their natural surroundings, providing camouflage from predators.

Sexing

Sexing Reticulated Corydoras is easiest when they are mature. Females are slightly larger and have a more robust, rounded body shape compared to the slimmer, more streamlined males. Observing them from above can make these differences more apparent.

Breeding

Breeding Corydoras reticulatus in captivity remains challenging and has yet to be widely documented. In the wild, these fish are egg scatterers, laying their eggs on various surfaces such as plants, rocks, or the substrate. To encourage breeding in an aquarium, mimic their natural environment with soft, acidic water, plenty of hiding spots, and cooler water changes to simulate seasonal rainfall. Once breeding is successful, remove the adults to prevent egg predation.

Lifespan

When kept in optimal conditions, Reticulated Corydoras can live for 3-5 years. Proper diet, clean water, and a stress-free environment significantly contribute to their longevity.

Tank Setup and Behavior

Reticulated Corydoras are highly social fish and should be kept in groups of at least five to thrive. A sandy substrate is essential to protect their delicate barbels from injury. Add decorations like driftwood, smooth rocks, and plants to create hiding spots and mimic their natural habitat. Ensure the tank is free from aggressive or overly active fish, as this species is peaceful and can become stressed in the presence of boisterous tank mates.

These Corydoras are active foragers, spending most of their time sifting through the substrate for food. Their social and peaceful nature makes them excellent companions in community tanks with other non-aggressive species.

Short Description

Also known as the "network Cory," Corydoras reticulatus is a striking and hardy species, ideal for beginner aquarists. Their unique pattern, peaceful demeanor, and manageable size make them a popular choice for freshwater tanks. These social fish thrive in small groups and bring life and charm to any aquarium setup.
