Zebra Danio

Also called the Zebrafish, the Zebra Danio belongs to the minnow family and is a popular resident in community tanks. These fish are native to the small streams in the southeastern region of the Himalayas, particularly India, Pakistan, Nepal, Bangladesh and Mayanmar. Zebra Danios are easily recognized by their silver, laterally compressed bodies ornamented with gold or blue stripes. Zebra Danios can also be found in fluorescent color variants like green, red and yellow under the name GloFish.

Tank Set-Up

These fish are particularly popular for beginning aquarists because they are hardy fish, able to wishstand a variety of tank conditions. Best kept in groups of six or more of their own species, Zebra Danios can also be kept with tetras and other cyprinids. This species prefers a heavily planted tank ornamented with driftwood, floating plants and dark substrate.

Feeding

These fish are micropredators in the wild, feeding on small crustaceans and invertebrates as well as insect larvae. In the home aquarium, Zebra Danios can be fed a staple diet of high-quality flake food supplemented with small live and frozen foods like Artemia, Daphnia, bloodworms and brine shrimp.

Breeding

Zebra Danios are relatively easy to breed. They are egg scatterers and thus prefer a breeding tank decorated with plenty of fine-leaved plants. Lining the bottom of the tank with mesh will help to prevent the adults from eating their eggs – the adults can also be removed from the tank after spawning. The breeding tank itself should be dimly lit and kept at a fairly neutral or slightly acidic pH. After spawning has occurred, the eggs typically hatch in 24 to 36 hours and the fry will become free swimming after another few days.
