Bandit Corydoras - Corydoras metae : Complete Fish Profile & Care Guide
Table of contents
Introduction
Bandit Corydoras (Corydoras metae), commonly found in the aquarium hobby, are well-suited for novice aquarists due to their remarkable hardiness. These Corydoras also excel as community aquarium inhabitants, owing to their small size and peaceful demeanour. To create an aesthetically pleasing display and ensure optimal well-being for these sociable and shoaling fish, it is recommended to keep them in groups of at least six or more individuals. Providing a soft sand substrate is crucial, as it allows Bandit Corydoras to forage and explore without the risk of abrasion or bacterial buildup that coarse gravel can pose to their delicate barbels.
Efficient filtration systems should maintain moderate water movement and adequate oxygenation to promote optimal health. Regular maintenance, including periodic partial water changes, is essential for the overall well-being of these fish. The aquarium should offer plenty of shaded areas created by driftwood, rocks, and dense plantings to provide a sense of security for the Bandit Corydoras.
When it comes to tankmates, Bandit Corydoras can coexist peacefully with a wide range of fish commonly found in the hobby, such as Dwarf Cichlids, Tetras, small to medium-sized Barbs, Gouramis, and other peaceful Catfish. While these Corydoras may occasionally prey on smaller Dwarf Shrimp, they pose no threat to larger shrimp or other ornamental invertebrates. It is advisable, however, to avoid housing them with larger, more aggressive fish that may intimidate or outcompete them for food.
Bandit Corydoras exhibit a distinct appearance, characterized by a light brownish beige colouration. Along the posterior portion of their bodies, an oblique dark bar extends from the edge of the dorsal fin to the base of the caudal fin, remaining separate from the fin itself. Their dorsal fins are predominantly transparent, with more than half of them tinted black, while their caudal fins display striking white and brown bands. Notably, a black eye band spans across both eyes, stretching over the top of the head, adding to their unique and captivating visual appeal.

Sexual Dimorphism
Distinguishing between the male and female Bandit Corydoras is generally a relatively straightforward task. Adult males of this species typically exhibit a slimmer body profile and are slightly shorter in length compared to their female counterparts. On the other hand, females tend to display a larger overall size, along with a noticeable roundness and breadth, particularly when they are carrying eggs.

Natural Habitat
The Bandit Corydoras is exclusively found in the Meta River Basin, which is located in Colombia, South America. This species thrives in natural habitats characterized by the presence of crystal-clear, rapidly flowing whitewater. These Corydoras primarily inhabit areas with a sandy substrate, which provides them with a suitable environment for their behavioural and ecological needs.
Breeding
Breeding Bandit Corydoras can be accomplished with relative ease by establishing a separate breeding tank housing two or more males per female. To initiate the spawning process, it is advisable to perform a substantial 50 to 70 per cent water change using cooler water while simultaneously enhancing oxygenation and flow within the tank. This practice should be repeated daily until the desired spawning occurs. Bandit Corydoras typically deposit their eggs on the tank glass, among fine-leaved plants, or within submerged spawning mops.
Once the spawning phase concludes, it is necessary to remove either the adult fish or the eggs from the breeding tank. If opting to transfer the eggs, it is vital to ensure that the raising tank possesses the same water parameters as the spawning tank, maintaining optimal oxygenation levels. To prevent the development of fungus, some breeders incorporate a few drops of methylene blue or introduce alder cones into the raising tank. The incubation period generally spans from 2 to 4 days, after which the fry consumes their yolk sacs. At this stage, providing small live foods such as microworm and baby brine shrimp is recommended to support the nutritional needs of the developing fry.
Rearing Corydoras fry can present a significant challenge, primarily due to their demanding requirements for excellent water quality. Maintaining a thin layer of sand as a substrate, as opposed to a bare tank, has been shown to decrease their susceptibility to diseases. Hence, careful attention to water quality and maintenance practices is essential throughout the fry's growth stages.
Diet & Feeding
The Bandit Corydoras readily accepts a variety of high-quality dried foods, including granules, flakes, and sinking pellets. These modern food formulations have been specifically developed to meet the nutritional needs and promote the overall health of these fish.
While these dried foods provide sufficient nourishment, offering occasional live, frozen, or freeze-dried meals such as bloodworms, daphnia, and tubifex once or twice a week can provide additional benefits to the well-being of the fish, although it is not necessary for their diet. It is important to note that bloodworms should be provided sparingly as a treat and should not be relied upon as the main diet, as they can be challenging for fish to digest and may potentially lead to blockages.
In their natural habitat, the Bandit Corydoras is an omnivorous species that consumes some vegetable matter. Although many commercially available fish foods incorporate plant-based ingredients, supplementing their diet with blanched vegetables like spinach, broccoli, and zucchini can be beneficial.
It is crucial to avoid overfeeding the fish and promptly remove any uneaten food to maintain water quality and prevent potential health issues. By ensuring a balanced diet and proper feeding practices, aquarists can support the health and vitality of their Bandit Corydoras while providing them with a varied and nutritionally complete diet.
