Hi-fin Danios are active, hardy, and schooling freshwater fish that thrive in groups of six or more, making them a great choice for community aquariums. They prefer a well-planted tank with open swimming space and a gentle current, mimicking their natural streams and rivers. These fish are adaptable but do best in stable, clean water with moderate flow and temperatures. Being omnivores, they readily accept a varied diet of flakes, pellets, and live or frozen foods. Peaceful by nature, they get along with most similarly sized community fish and are excellent for both beginners and experienced aquarists.
