Zebra Danio

The Zebra Danio is a lively schooling fish with crisp blue-dark and pale horizontal stripes. Its quick swimming and active social behavior add movement to the upper areas of a community aquarium, especially when a good-sized group has plenty of open space.

Fish details

• Scientific name: Danio rerio, also listed as Brachydanio rerio
• Size offered: 2.5 cm
• Adult size: Approximately 5–6 cm
• Origin: South Asia, including India and neighboring countries
• Water type: Freshwater
• Temperament: Generally peaceful but very active; may nip fins when poorly grouped

Recommended aquarium conditions

• Aquarium: 20 US gallons long or larger

• Social needs: At least 6; larger groups are preferable

Choose a long aquarium with plants around the edges and a clear central swimming area. Provide filtration and water movement without eliminating sheltered places. Keep a secure lid in place; these small fish are capable jumpers.

Diet and feeding

Zebra Danios readily take small flakes and pellets. Vary meals with frozen or live foods such as brine shrimp, daphnia, or small bloodworms. Feed portions that the group can finish promptly, and make sure their enthusiasm does not leave other fish hungry.

Compatibility and care

Pair them with similarly active, peaceful companions in matching conditions. Slow, long-finned fish may find their persistent activity stressful. Maintain the school size, avoid overcrowding, and monitor chasing or fin damage. Although adaptable, Zebra Danios still require an established filter, clean water, and gradual acclimation; they should not be used to cycle a new tank.
