Its range is concentrated within the Ganges and Brahmaputra River basins, and the species was first described from Kosi River (decrease Ganges basin) of India. Its range additional south is more native, with scattered information from the Western and Eastern Ghats areas.

It has regularly been mentioned to happen in Myanmar (Burma), however, that is fully based mostly on pre-1930 information and certain refers to shut family members solely described later, notably Danio kyathit.

Likewise, old information from Sri Lanka is extremely questionable and stays unconfirmed.

Danio Zebrafish have been launched to California, Connecticut, Florida, and New Mexico within the United States, presumably by the deliberate launch by aquarists or by escape from fish farms.

The New Mexico inhabitants had been extirpated by 2003 and it’s unclear if the others survive because the final printed information has been a long time ago. Elsewhere the species has been launched in Colombia and Malaysia.

Danio Zebrafish Description

The Danio Zebrafish is known for the 5 uniform, pigmented, horizontal, blue stripes on the aspect of the body, that are paying homage to a zebra’s stripes, and which lengthen to the end of the caudal fin. Its form is fusiform and laterally compressed, with its mouth directed upwards.

The male is torpedo-shaped, with gold stripes between the blue stripes; the feminine has a bigger, whitish stomach and silver stripes as an alternative to gold.

Adult females exhibit a small genital papilla in front of the anal fin origin. The Danio Zebrafish can attain as much as 4–5 cm (1.6–2.Zero in) in size, though they sometimes are 1.8–3.7 cm (0.7–1.5 in) within the wild with some variations relying on location.

Its lifespan in captivity is around two to a few years, though, in best circumstances, this can be prolonged to over 5 years. In the wild, it’s sometimes an annual species.

Danio Zebrafish sometimes inhabit reasonably flowing to the stagnant clear water of fairly shallow depth in streams, canals, ditches, oxbow lakes, ponds, and rice paddies.

There is often some vegetation, both submerged or overhanging from the banks, and the underside is sandy, muddy, or silty, typically blended with pebbles or gravel.

In surveys of Danio Zebrafish places all through a lot of its Bangladeshi and Indian distribution, the water had a near-neutral to considerably primary pH and largely ranged from 16.5 to 34 °C (61.7–93.2 °F) in temperature.

One unusually chilly site was solely 12.3 °C (54.1 °F) and one other unusually heat site was 38.6 °C (101.5 °F), however, the Danio Zebrafish nonetheless appeared wholesome.

The unusually chilly temperature was at one of many highest identified Danio Zebrafish places at 1,576 m (5,171 ft) above sea level, though the species has been recorded to be 1,795 m (5,889 ft).

In the aquarium

Danio Zebrafish are hardy fish and regarded as good for newbie aquarists. Their enduring reputation might be attributed to their playful disposition, in addition to their speedy breeding, aesthetics, low-cost value, and broad availability.

They additionally do properly in colleges or shoals of six or more and work together properly with different fish species within the aquarium. However, they’re prone to Oodinium or velvet illness, microsporidia (Pseudoloma neurophilia), and Mycobacterium species.

Given the chance, adults eat hatchlings, which can be protected by separating the 2 teams with a web, breeding field, or separate tank. In captivity, Danio Zebrafish reside roughly forty-two months. Some captive Danio Zebrafish can develop a curved backbone.

The zebra danio was additionally used to make genetically modified fish and have been the first species to be bought as GloFish (fluorescent colored fish).

Danio Zebrafish Aquarium Conditions

You ought to select an elongated aquarium and it’s obligatory is to cover the tank with glass.

You ought to keep a proportion of Four liters of water per adult. Danio Zebrafish are education fish. Therefore they need to be saved in 6-7 specimens.

Aeration and lighting: Fish want well-lit aquariums with fixed oxygen saturation. Especially related is air purging with rising water temperature.


Danio Zebrafish are omnivorous, primarily consuming zooplankton, phytoplankton, bugs, and bug larvae, though they will eat quite a lot of different meals, comparable to worms and small crustaceans, if their most popular meals sources aren’t available.

In the analysis, adult Danio Zebrafish are sometimes fed with brine shrimp or paramecia.

Danio Zebrafish Breeding

For the manufacturing of offspring, one feminine and two to a few males are chosen, which are saved for a number of hours in a spawning aquarium.

As a rule, that is finished within the night. During fertilization, the feminine begins to spawn within the morning. The male actively pursues the feminine till the eggs fly out of it. Males then fertilize the eggs situated beneath the vegetation.

At the end of the process, calm and drained males go on a trip, and the feminine noticeably loses the roundness of the stomach.

On average, the feminine provides as much as 200 eggs. The use of antifungal medication will assist save them sooner or later.

After about 48 hours, the litter matures. Larvae hatch to the light hooked up to any close by the floor and motionlessly freeze. After 5−6 days, you may discover the formation of fry feeding on ciliates.

Danio Zebrafish Tank Mates

Best tankmates for Danio Zebrafish are tetras, swordtail fish, mollies, catfish, and betta fish. Contact with goldfish, eels, shrimps, and cichlids must be restricted.

Common Diseases

One of the important factors of preserving pets is information on the primary illnesses and strategies of their therapy. Most typically, people of this species encounter the next ailments:

Danio Zebrafish analysis

Danio Zebrafish are extensively used as model organisms to check the event of vertebrate creatures and the features of their genes.

Studying Danio Zebrafish for scientific analysis was proposed by Streisinger George. After that, the significance of the model has been repeatedly confirmed by much genetic research.

The benefits of finding out people over different vertebrates are:

High embryo improvement and passage from the egg stage to the larva in lower than three days.

Healthy, hardy, transparent embryos develop outdoors the maternal womb, which considerably facilitates the process of manipulation and remark.

Due to the high pace and comfort of labor, Danio Zebrafish can act as fashions for phenotypic screening of developed medicinal substances.

Some genetic engineering strategies permit the event of traces that partially imitate quite a lot of human ailments.

In addition to their exceptional look, These fishes are of great scientific curiosity attributable to their talents for speedy genetic modifications. Learn more about best-places-to-fly-fish-in-Montana.
