Leopard Corydoras (Corydoras Trilineatus)

The Leopard Corydoras is frequently confused with the Corydoras julii. By looking at their horizontal stripes, you can tell them apart. The stripes of this species are thicker. In terms of aquarium care, the two species have very similar needs.

This fish is prevalent in the community aquarium because of their looks and personalities.

The Leopard Catfish is covered in overlaying scales referred to as plates or scutes. The Leopard Catfish is covered in overlaying scales referred to as plates or scutes. From the gill covers to the tail end, a narrow dark stripe runs along the sideline of the fish's body. A pale area with spots is found on both sides of this stripe.

The caudal fin is translucent with rows of dark spots that create stripes vertically through the tail. The dorsal fin is colourless with a large black spot on the upper portion, and the anal and adipose fins are also translucent with a row of spots running through them. The head is covered in dots that blend in a mottled pattern and sensitive barbels surround the mouth.

Like other catfish species, the dorsal, pectoral and adipose fins have a spiked fin ray that can be barred, making them difficult for a predator to swallow.

Natural Habitat

Suriname River


In the home aquarium, the Leopard Corydoras will readily accept most good quality dried foods such as granules, flakes and sinking pellets. These modern food products have been developed to provide all adequate nutrition to maintain your fish's health and dietary requirements.

Providing additional foodstuffs such as live, frozen, and freeze-dried meals such as bloodworm, daphnia, and tubifex once or twice a week will provide additional benefits to your fish's health and well-being but is not a must for this fish.

It should be noted that bloodworms should only be given as an occasional treat and should not be used as the staple diet as they are difficult for fish to digest and can potentially cause blockages.

This fish is an omnivore in the wild, meaning it will consume some vegetable matter. Although most modern fish foods take this into account and include them in their products, you can still supplement your fish's diet with blanched vegetables such as spinach, broccoli, and zucchini. Ensure you do not overfeed your fish and remove any leftovers the following day.

The Sexual differences between this species are easily determined when looking from above.
