Corydoras trilineatus

The Three-lined Corydoras, often called the Leopard Cory, is a peaceful and charming bottom-dwelling catfish that brings a lot of activity to the lower levels of an aquarium. Due to its similar spotted and striped pattern, it is frequently confused with its relative, the Julii Cory. This is a very social fish that thrives in groups; you should always keep them in a school of at least six individuals. When kept alone, they can become shy and stressed. In a group, they will feel secure and you'll get to see their playful, active nature as they explore the tank together.

For their home, it's best to use a soft, sandy substrate. They have sensitive whiskers, called barbels, which they use to sift through the bottom looking for food. Gravel can be sharp and may damage these important sensory organs. They are not picky eaters but require food that sinks to the bottom, such as specialized pellets or wafers, as they won't be able to compete for flakes at the surface. They are excellent members of a 'clean-up crew' as they will constantly graze on leftover food and edible organic films. One of their most interesting behaviors is their ability to breathe air. You may occasionally see one make a quick dash to the surface for a gulp. This is completely normal and a fascinating adaptation, though if it happens too frequently, it may be a sign to check your water oxygen levels.
