🐡 Emerald Cory Corydoras splendens

The Emerald Cory (Corydoras splendens) is a easy-care, peaceful species from South America. Adults reach roughly 3", so plan on a minimum tank of 20 gallons. Keep the water between 72–79°F with a pH of 6–7.5. This is a schooling fish — keep a group of at least 6 so it feels secure and colors up. As an omnivore, it does best on a varied diet appropriate to its feeding style.
