In the wild, Zebra Danios are found in streams, ponds, and rice paddies across India, Bhutan, and Bangladesh, where they thrive in well-oxygenated waters with moderate currents. In aquariums, they require similar conditions with plenty of open swimming space and a gently moving current. Dense plantings or decorations provide shelter and help mimic their natural environment. Their active, social nature makes them ideal for groups of six or more, where they exhibit natural schooling behaviors.

These fish are omnivores and thrive on a varied diet that includes high-quality flakes, micro-pellets, and live or frozen foods like brine shrimp or daphnia. Regular water changes and stable parameters are essential for their health, as their long fins can make them slightly more vulnerable to poor water quality or fin-nipping tankmates.
