Corydoras similis

Corydoras similis, also known as the False Julii Corydoras or Smudge Spot Corydoras, is indeed a small freshwater catfish species belonging to the Corydoradinae subfamily. These peaceful and social fish are native to the Amazon River basin in South America.

As the name suggests, Corydoras similis is often mistaken for Corydoras julii due to their similar appearance. They have a striking pattern with a series of black spots and speckles on a light background, along with a prominent black stripe that runs from their eyes to their caudal fin.

Like other corydoras catfish, C. similis is a bottom-dwelling fish that enjoys sifting through the substrate in search of food. They are scavengers and will help keep the aquarium clean by consuming leftover food and debris.

These fish are best kept in small groups of at least six individuals as they are social and prefer the company of their own kind. They are generally peaceful and can be kept in a community aquarium with other non-aggressive fish of similar size. It’s essential to provide them with a well-maintained tank with plenty of hiding spots, such as plants, rocks, and driftwood.

Remember that fishkeeping guidelines might evolve over time, so always ensure to research up-to-date care requirements before adding any new fish to your aquarium.
