Leopard Corydoras (lat. Corydoras julii) is a species of ray-finned fish from the order Siluriformes, family Callichthyidae, genus Corydoras. One of the most beautiful and popular representatives of armored catfish in the aquarium hobby.

Distribution. The natural range of the Leopard Corydoras covers rivers and streams of South America, mainly in the Amazon, Parnaíba and Paraíba river basins in Brazil. The fish prefer slow-moving or stagnant waters with sandy or muddy bottoms, often found in small rivers, streams and floodplain lakes with dense vegetation. It has been recorded as an introduced species in some countries.

Care requirements. The Leopard Corydoras is a catfish that grows up to 5–6 cm in the aquarium. To keep a school (minimum 6–8 specimens), an aquarium of at least 60 liters with a length of 60 cm is recommended. It is important to keep them in schools, as they are social fish and feel comfortable only in a group. Optimal water parameters: temperature 22–26°C, hardness 5–15 dGH, pH 6.0–7.5. Filtration with moderate flow, aeration and weekly water changes of 20–25% are necessary. Sandy or fine gravel substrate, driftwood, stones and shelters are placed at the bottom. Plants are planted in the substrate, creating dense thickets.

Leopard Corydoras are omnivorous, feeding on small invertebrates, worms and organic debris in the wild. In the aquarium, their diet should consist of high-quality sinking flakes, pellets, live and frozen foods (bloodworms, tubifex, brine shrimp, daphnia). It is important to vary the diet and provide protein-rich food. Feed should be 1–2 times a day in small portions.

In the aquarium, Leopard Corydoras are active in the lower water layers. They are peaceful and get along well with any peaceful fish. Recommended tankmates include tetras, rasboras, danios, barbs, gouramis, other corydoras and any peaceful fish. It is not recommended to keep them with large or aggressive fish that may bully them.

Breeding in home aquariums is possible under proper conditions. Leopard Corydoras are egg-laying fish, spawning on plant leaves, driftwood or glass. They reach sexual maturity at 8–10 months. To stimulate spawning, water changes with fresh, cool water and increased aeration are recommended. Males and females form temporary pairs. Eggs incubate for 3–5 days, fry begin to swim after 3–4 days. Fry are fed infusoria, Artemia nauplii and fine dry food.

The Leopard Corydoras gets its name in honor of the ichthyologist Julii and its characteristic coloration: the body is silvery-grey or cream with black spots and speckles forming a reticulated pattern resembling leopard spots. Males have brighter coloration and are slimmer, females have a fuller body. Life expectancy is 5–8 years.
