Food and Feeding

Corydoras leopardus are not picky eaters and will accept most commercial aquarium foods. Their diet should include sinking algae wafers, spirulina tablets, and high-quality flake food. To provide variety and protein, offer occasional treats of frozen or live bloodworms, daphnia, or brine shrimp. Feeding in the evening is recommended, as they are most active at dusk.

Origin

Leopard corys originate from the upper Amazon basin, specifically in Peru and Ecuador. In the wild, they inhabit clear, slow-moving streams and tributaries with sandy or muddy bottoms, often surrounded by dense aquatic vegetation and leaf litter.

Sexing

Sexual dimorphism is present. Males are typically smaller and slimmer, while females appear larger and rounder, especially when viewed from above during spawning periods.

Breeding

Corydoras leopardus can be encouraged to spawn in clean, soft water with slightly lower temperatures. A drop of 2–3 °C can trigger spawning. The female deposits small batches of sticky eggs on plant leaves or aquarium glass. To prevent fungus, transfer the eggs to a separate rearing tank with gentle aeration. Eggs hatch in 4–5 days; feed the fry with infusoria and then newly hatched brine shrimp.

Lifespan

With proper care and stable conditions, Leopard corys can live 5–7 years, sometimes even longer in well-maintained aquariums.

Short Description

Corydoras leopardus are peaceful bottom-dwellers with a beautiful spotted pattern reminiscent of a leopard, making them popular in community tanks. They thrive in groups of at least 6 individuals, displaying more natural behavior and feeling safer in numbers. Provide a soft sand or fine gravel substrate to protect their sensitive barbels, and include hiding places made of driftwood, rocks, or leaf litter.

Recommended plant species include Amazon sword, Cryptocoryne, Java fern, and floating plants like Pistia or frogbit to diffuse lighting. Compatible tankmates include peaceful species such as neon tetras, rasboras, honey gouramis, Otocinclus, and other small Corydoras. Ensure good filtration and regular water changes to maintain optimal water quality.
