Bandit Corydoras (Corydoras metae)

Bandit Corydoras are very common in the hobby and are suitable for beginner aquarists as they are a very hardy species. These Corys also make fantastic community aquarium fish due to their small size and peaceful nature. However, to create a beautiful display and let these sociable, shoaling fish feel more comfortable, you should keep them in groups of at least six, preferably more.

Soft sand substrates are ideal for keeping Bandit Corydoras so they can root around and forage without risk of abrasion and bacteria from accumulated waste; coarse gravel can damage their barbels.

For filtration to be efficient, there should be moderate water movement and a decent level of oxygenation. For these fish to remain healthy, regular maintenance, including periodic partial water changes, is necessary. Make sure there are plenty of shady spots amongst the driftwood, rocks, and dense plantings.

You can keep Bandit Corydoras with most fish available in the hobby, including Dwarf Cichlids, Tetras, small to medium-sized Barbs, Gouramis and other peaceful Catfish. These Corys may prey on some more petite Dwarf Shrimp but are safe with larger shrimp and other ornamental invertebrates. However, it would be best if you refrained from keeping these fish with larger, more aggressive fish as they will feel intimidated and get outcompeted for food.

Bandit Corydoras have a light brownish beige colour, and on the posterior portion of their bodies, they have an oblique dark bar that extends from the dorsal fin edge to the caudal fin base but does not extend onto the fin or split in two. Their dorsal fins are transparent, with slightly more than half of them tinted black, while their caudal fins have white and brown bands. Their dorsal fins are transparent, with slightly more than half of them tinted black, while their caudal fins have white and brown bands. A black eye band covers both eyes, stretching across the top of the head.

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 somewhat straightforward to differentiate between the male and female Bandit Corydoras. Adult males will be slimmer and a little shorter than females. In contrast, the females grow larger and are noticeably rounder and broader than males, especially when carrying eggs.
