🐟 Pearl Danio Danio albolineatus

The Pearl Danio (Danio albolineatus) is a easy-care, semi-aggressive species from Southeast Asia. Adults reach roughly 2.5", so plan on a minimum tank of 20 gallons. Keep the water between 68–78°F with a pH of 6.5–7.5. 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.
