A peaceful, highly social bottom-dwelling catfish known for its striking leopard-like spots and elongated snout. Unlike many fish, Corydoras require fine sand substrate to prevent severe damage to their delicate sensory barbels. They are obligate shoaling fish and must be kept in groups of at least 6 to feel secure and display natural continuous foraging behaviors.

Leopard Cory Care Guide Summary
The Leopard Cory, scientifically known as Corydoras leopardus, belongs to the Catfish family group. Adults reach a maximum size of approximately 6.1 cm and have a fusiform body shape with a moderate growth rate. Classified as peaceful, this species primarily occupies the bottom zone of the aquarium and produces a low level of biological waste.
To thrive, the Leopard Cory requires a freshwater only aquarium with a minimum volume of 60 litres and a tank length of at least 60 cm. Water temperature should be maintained between 22°C and 26°C, with a pH range of 6–7.5 and a general hardness of 2–15 dGH. A moderate water flow is preferred.
The Leopard Cory is a rewarding species to keep, provided its core environmental needs are met. The Leopard Cory is typically available in one standard form.
Leopard Cory Habitat Setup
When setting up an aquarium for the Leopard Cory, a moderate water flow best suits their natural preferences. Because this species occupies the bottom zone, the aquarium layout should prioritise sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include a sand substrate to accommodate their sifting behaviour. Keepers should note that expect substrate disturbance, so lightweight décor should be secured.
Leopard Cory Compatibility Notes
Classified as peaceful, the Leopard Cory is a schooling species that feels most secure in a sizeable group, where natural shoaling behaviour reduces stress and brings out their best colours. When choosing tankmates, their energetic swimming style may stress more sedentary or timid species. Selecting tankmates that favour different water layers from the bottom zone can help reduce competition and territorial overlap.

Fish Similar to Leopard Cory
Bronze Corydoras
Corydoras aeneus
A highly popular, peaceful schooling catfish known for its armor-like scales (scutes) and active bottom-feeding behavior. They are essential clean-up crew members but require a dedicated sinking diet (not just leftovers). Sand substrate is strictly required to prevent erosion and infection of their sensitive barbels. They are 'gut breathers' and will occasionally dart to the surface to gulp atmospheric air.
Julii Corydoras (False Julii)
Corydoras trilineatus
Often sold in the aquarium trade as the 'Julii Cory', the False Julii (Corydoras trilineatus) is a peaceful, highly social bottom-dweller. It features a distinct reticulated (maze-like) pattern on its head and a prominent horizontal stripe down its body. As an obligate schooling fish, it must be kept in groups to thrive and feel secure. A soft sand substrate is absolutely critical to prevent the erosion of their sensitive foraging barbels.
True Julii Corydoras
Corydoras julii
A highly sought-after, peaceful schooling catfish native to the lower Amazon. They feature distinctive fine black dots on their heads (unlike the reticulated, maze-like lines of the commonly mislabeled 'False Julii', C. trilineatus) and a black-tipped dorsal fin. As obligate bottom-dwellers, they continuously sift through the substrate and strictly require soft sand to prevent erosion and infection of their delicate sensory barbels. They are highly gregarious and must be kept in groups.
Loxozonus Corydoras (C079/C082)
Corydoras loxozonus
A peaceful, bottom-dwelling catfish native to the Rio Meta basin in Colombia. Known for the distinctive diagonal black stripe across its back and a mask over its eyes. Like all Corydoras, they are highly social and must be kept in groups. A soft, sandy substrate is strictly required to prevent damage to their delicate barbels as they sift for food.
Bandit Cory
Corydoras metae
A highly social, peaceful bottom-dwelling catfish endemic to the Rio Meta basin in Colombia. Instantly recognizable by the black 'bandit' mask over its eyes and the dark ridge stripe along its back. Like all Corydoras, they must be kept on a soft sand substrate to prevent severe damage and infection to their sensitive foraging barbels. They are schooling fish that require groups of at least 6 to thrive and display natural behavior.
Peppered Corydoras
Corydoras paleatus
One of the most popular and hardy Corydoras species. Notably, they prefer cooler water temperatures than most tropical fish. They are peaceful, bottom-dwelling schooling fish that use their sensitive barbels to sift through the substrate for food. They must be kept in groups to thrive.
