Leopard Corydoras (Corydoras Trilineatus)

The Eloquent Leopard Corydoras, also known as the False Julii Corydoras and the Three stripe Corydoras (Corydoras Trilineatus), is frequently confused with the Corydoras julii. However, Corydoras julii has distinguishing black dots on its head, whereas Leopard Corys have these dots grouped together. In terms of aquarium care, the two species have very similar needs.

The Leopard Corydoras is a small, peaceful freshwater Catfish that has become prevalent in the community aquarium because of its looks and personality. This fish is easy to care for and incredibly hardy but can be somewhat shy.

It is best to keep Leopard Corydoras in groups of at least six individuals, preferably more, since they are a shoaling species in nature. The more fish you keep, the more comfortable they will feel, resulting in more natural behaviour.

Rasboras, smaller Barbs, Pencilfish, Dwarf Cichlids, Angelfish, and Tetras, are all possible tankmates for Leopard Corydoras. However, These Corys should not be housed with other bottom-dwelling species like Rainbow Sharks that may become territorial, as they can soon become intimidated and stressed.

The Leopard Corydoras is covered in overlaying scales referred to as plates or scutes. As well as having a row of connected dots along the length of each side of the body, these Corys also have a silver body with many linked, merged black dots. Additionally, it has a series of black dots on its caudal and a black marking on the tip of its dorsal fin.

The dorsal, pectoral, and adipose fins of Corydoras species have spiked fin rays that can be barred, making them difficult to swallow for predators.

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.

Sexual Dimorphism

The Sexual differences between this species are easily determined when looking from above. The females have a broader body that is rounder than the males, and the females are usually bigger than the males.
