One of the main advantages of keeping Corydoras in a community tank is their scavenging behavior. They are bottom-dwelling fish that constantly sift through the substrate in search of food. Not only does this help keep the tank clean, but it also adds an interesting dynamic to the tank as they dart around the bottom in search of tasty morsels.
When it comes to tankmates, Corydoras are compatible with a wide range of fish species. They are generally peaceful and can coexist with other peaceful community fish such as tetras, gouramis, rasboras, and livebearers.
