The Little Cory is known for its sociable and peaceful nature, making it an excellent addition to community tanks. These fish exhibit a playful demeanor, often seen darting around the aquarium in small groups. They are bottom dwellers and prefer to stay close to the substrate, where they forage for food and explore their environment. Their natural behavior includes sifting through the substrate with their barbels, searching for detritus and other organic matter. This behavior not only keeps them active but also contributes to the overall cleanliness of the tank. Little Corys thrive in groups of at least six individuals, as they feel more secure and exhibit more natural behaviors when in a school. Their peaceful temperament allows them to coexist harmoniously with a variety of tank mates, making them a favorite among aquarists.
Creating the ideal environment for your Little Corydoras involves replicating their natural habitat as closely as possible.
