Corydoras solidalis, also known as the Solid Cory or Emerald Cory, requires proper tank care to thrive. These small catfish are native to South America and prefer living in a peaceful community aquarium. A tank size of at least 20 gallons is suitable for a small group of Solid Corys. Provide a sandy substrate and plenty of hiding spots like caves or driftwood. Maintain a temperature between 72°F and 78°F (22°C to 26°C) and a pH level of 6.5 to 7.5. They are omnivorous, so a varied diet of high-quality pellets, flakes, and occasional live or frozen foods is recommended. Regular water changes and a clean environment are crucial for their well-being.
