Tank Size: Provide a tank of at least 20-30 gallons for a small group of Emerald Corys, as they thrive in groups and need ample swimming space. Water Parameters: Maintain stable conditions with a temperature range of 72-78°F (22-26°C), a pH level of 6.5-7.5, and soft to moderately hard water. Filtration: Use efficient filtration to maintain good water quality and oxygenation. Corydoras are sensitive to poor water conditions. Aquascape: Create a tank with sand or smooth gravel substrate to protect their delicate barbels. Provide hiding spots like caves, driftwood, and plants. Tank Mates: Emerald Corys are peaceful and can be kept with other small, non-aggressive community fish. They do best in the company of their own kind. Diet: They are omnivores, accepting high-quality sinking pellets, live or frozen foods like bloodworms, brine shrimp, and occasional vegetable matter.
