🐟 Zebra Danio Danio rerio

The Zebra Danio (Danio rerio) is a easy-care, semi-aggressive species from South Asia (Ganges and Himalayan streams). Adults reach roughly 2", so plan on a minimum tank of 10 gallons. Keep the water between 64–77°F with a pH of 6.5–8. This is a schooling fish — keep a group of at least 6 so it feels secure and colors up. It tends to nip fins, so avoid slow, long-finned tankmates. As an omnivore, it does best on a varied diet appropriate to its feeding style.
