Corydoras semiaquilus, a member of the Corydoradinae subfamily in the Callichthyidae family, is a tropical freshwater fish native to inland waters of South America. Specifically, it is found in the western Amazon River basin, spanning regions of Brazil and Peru.
This species of fish can reach a maximum length of approximately 2.4 inches (6.0 cm). It thrives in a tropical climate, preferring water with a pH range of 6.0 to 8.0, a water hardness of 2.0 to 25 dGH, and a temperature range of 72 to 79 °F (22 to 26 °C). Its diet consists of various food sources, including worms, benthic crustaceans, insects, and plant matter.
When it comes to reproduction, Corydoras semiaquilus lays its eggs in dense vegetation. Unlike some species, the adults do not actively guard the eggs. Instead, the eggs are left in their natural environment, relying on the surrounding conditions for successful incubation and hatching.
In summary, Corydoras semiaquilus is a tropical freshwater fish species originating from the western Amazon River basin in Brazil and Peru. It has specific preferences for water conditions and sustains itself by consuming a variety of prey and plant matter. Its reproductive behavior involves egg-laying in dense vegetation, with no parental care provided by the adults.
