Corydoras arcuatus - Arched Corydoras (South America)

The Arched Corydoras - Corydoras arcuatus is a small bottom-dwelling fish native to South America. It belongs to the family Callichthyidae and the dwarf catfish. Indeed, its size is commonly around 4 cm. The male often has a less rounded abdomen than the female and has pointed dorsal fins, whereas those of the female are more rounded. This species lives in schools and adopts a diurnal lifestyle.

In its natural environment, the Arched Corydoras is exposed to neutral water, neither too basic nor very acidic. A pH of 6 to 7.5 is then tolerable. The water should, on its side, maintain a temperature between 22°C and 26°C. As explained earlier, this fish lives in colonies, which requires an aquarium setting of at least 8 individuals with a water capacity of 120 L. Since this fish spends the day sifting through the sand, care must be taken to ensure that the substrate is not sharp, as it could cut the fish's barbels. Its omnivorous diet makes it easy to feed and thus to raise.
