Temperament with other species: Peaceful
Tank Level: Bottom Level
Feeding: Provide them with vegetable matter in the form of sinking pellets or even spirulina pellets, they will also readily accept meaty foods such as blood worms or brine shrimp.
Sexing: Difficult allthough females tend to be larger and rounder than males. Males will typically have more pointed fin tips as they mature, compared to more rounded on the female.
Breeding: All Corydoras species can be bred in the same manner. It is best to set up a separate breeding tank and use an air driven sponge filter for ease of maintenance and better control of the water flow. Add two males per female and keep the water quality high. The parent fish should be conditioned on live or frozen foods and in a couple of weeks the females should start to swell with eggs. You can add spawning mops but these fish will deposit their eggs everywhere including the aquarium glass. Do a large water change with cooler water to induce spawning and once this has been completed remove the parent fish. The eggs will take 3 - 4 days to hatch but do not feed at this stage as the fry will consume their yolk sacs for the initial feeds. Once the fry are free swimming they can be fed on newly hatched brine shrimp or a commercial egg layer feed. Perform daily water changes with a small syphon tube to prevent any fry being removed until they are large enough to be treated like the parents and can accept larger foods.
Note: Always use fine gravel or sand for the tank substrate, this will prevent damage to the barbels of the fish. Corys need to be kept in small groups of at least 6 fish and provide adequate hiding places for them in the tank.
