Bandit Corydoras (Corydoras melini)

The Bandit Corydoras is an excellent looking, friendly and peaceful bottom dweller that do best when maintained in a group of 5 or more of its own species. However, three or four will be fine as long as there are other cory species in the same tank. These Corydoras are perfect for a community aquarium with other non-aggressive fish with comparable water requirements.

Their short and compact browny-beige body distinguishes the Bandit Corydoras. They sport a black eye mask and black lateral stripe that extends into the lower lobe of the caudal fin. This stripe divides just after the dorsal fin, leaving the dorsal ridge buff coloured. Sometimes a line of spots runs from the gill covers along the lateral line, and between this and the major, some pale striping is visible. The gill covers have a golden-yellow shimmer. Their fins are yellowish and transparent, with the front half of the fin having a dark colouration extending to the apex. The pectoral, dorsal and adipose fins are each preceded by a spine which is a hardened and modified ray.

Natural Habitat

Meta River


In the home aquarium, the Bandit 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

It is relatively straightforward to differentiate male from female Bandit Corydoras. The females are more extensive and have broader bodies than the males mostly when full of eggs and their ventral fins are rounded whereas the males are more slender and their ventral fins are pointed.
