Danio, any of several thin tropical fish belonging to the genus Danio and Brachydanio of the carp family Cyprinidae. Danios is tough and often swims in school. They are usually about 4-5 cm (1.5-2 inches) long. Some are often kept in family aquariums. These include the zebrafish or zebrafish (B. rerio), a popular species with longitudinal blue and yellow stripes, and the giant zebrafish (D. malabaricus), a blue and yellow striped fish. 

Zebra Danio (Danio rerio) is a striking little freshwater fish that has long attracted fish lovers. In fact, they are one of the most popular pet fish on the market! Due to its lively nature and high adaptability, this species is an excellent choice for new fish farmers and experienced aquarists.

In this article, we will discuss the unique characteristics of the zebra fish, green zebra fish along with the types of the zebra danio fish.

Green Zebra Fish

Zebra fish, any member of both unrelated businesses of fishes, the freshwater species withinside the genus Danio (own circle of relatives Cyprinidae; order Cypriniformes) and the saltwater species withinside the genus Pterois (own circle of relatives Scorpaenidae; order Scorpaeniformes). The zebra danio (Danio rerio), a famous freshwater aquarium fish at the start from Asia, is small (as much as approximately four cm (which is almost 1.5 inches long) and has dark-blue and silvery longitudinal stripes.

The zebrafish (Danio rerio) is a freshwater fish belonging to the minnow's own circle of relatives (Cyprinidae) of the order Cypriniformes. Native to South Asia, it's far a famous aquarium fish, regularly bought beneath the change called zebra danio (and consequently regularly referred to as a "tropical fish" despite the fact that each is tropical and subtropical).

The zebrafish is a crucial and extensively used vertebrate version organism in clinical research, as an instance in drug development, mainly pre-scientific development. It is likewise awesome for its regenerative abilities and has been changed with the aid of using researchers to provide many transgenic strains.

The Electric Green Danio fish is a genetically changed Zebra Danio, that has been genetically changed with a fluorescent protein gene and selectively bred to beautify the clearly taking place however uncommon fluorescent colouration. Scientists have been capable of taking the fluorescent protein genes which happens clearly in a few marine organisms and implant them into more than one species of freshwater tropical fish. Green zebra fish are bought inside the aquarium, interest these days are bred from the offspring of fluorescent fish that have been at the start evolved numerous years ago.

The exclusive saltwater zebra fishes (Pterois), utilized in marine aquariums, have extraordinarily big pectoral fins, several extraordinarily toxic spines, and colourful vertical stripes. Some species are normally regarded with the aid of using the names lionfish and turkey fish.

The Green Zebra Fish Overview:

• Common names: Striped danio, zebra danio, zebrafish

• Scientific name: Danio rerio

• Size: 2 inches

• Life span: 5 years

Salient Features of the Zebra Danio Fish

The zebra fishes are highly sensitive and most popular as the aquarium fishes because of their outlook and pretty stripes. It makes it more interesting to study their anatomy and their features to understand these beautiful creatures. It is very essential to study the salient features of considered creatures to have systematic learning along with the detailed description of the zebra danio fish. 

In the salient features of the zebra danio fish, we will study the description of the zebra fish or zebra danio fish, habitat, range, the diet of the zebra danio fish, etc. Let us start with the description of the zebra danio fish, as listed below:

Description of the Zebra Danio Fish

Zebrafish is a derived member of the genus Brachydanio from the Cyprinidae family. Has a sister relationship with the Daniox snake. Zebrafish are also closely related to the genus Devario, as indicated by the phylogenetic tree of closely related species. Zebrafish are often referred to as "Danio Relo", but recent molecular studies suggest that zebrafish should belong to the genus Slender danios like Brachydanio Relo. 

The zebrafish owes its name to its 5 horizontal, uniform and colored stripes on both sides of its body. They are reminiscent of the stripes of a zebrafish and extend to the edge of the caudal fin. Its shape is fusiform, compressed on the side, with the mouth facing upwards. The male is torpedo-shaped, with yellow stripes between the blue stripes. Women have a big white belly and stripes of silver instead of gold. 

Adult females have a small reproductive papilla in front of the base of the anal fin. Zebrafish can grow up to 5 cm (1.6-2.0 inches), but in the wild, it is usually 1.8-3.7 cm (0.7-1.5 inches) long, but there are some differences between the places. Life expectancy in captivity is around 2-3 years but ideally can extend to 5 years or more In nature, it is usually annual. 

Appearance of the Zebra Danio Fish

At first glance, these fish are definitely named after the iconic animals of the Serengeti. Their most recognizable feature is the horizontal stripes that extend from the gills to the tail. The stripes are generally violet-blue. It may appear black or grey depending on lighting conditions. The dark stripes are offset by the brilliance of gold and silver. 

A subtle splash of red creates a flash-like look above and below the fish. The transparent fins, on the other hand, give a symbolic appearance in the shape of a torpedo. The only fin not obvious is the denser striped anal fin. The difference between men and women is very small. Men tend to be small and thin. They are in the form of more aerodynamic torpedoes. However, women are somewhat plump and plump. 

Range of the Zebra Danio Fish

Zebrafish is native to the freshwater habitats of South Asia and is found in India, Pakistan, Bangladesh, Nepal and Bhutan. The northern border is in the southern Himalayas, which stretches from the Sutlej River basin on the Pakistan-Indian border to Arunachal Pradesh in northeast India. Its range is concentrated in the basins of the Ganges and Brahmaputra rivers, and the species was first described in the Koshi River (lower Ganges) in India. 

Its range is further south, with records distributed throughout the Western and Eastern Ghats. Often referred to as occurring in Myanmar (Burma), this is based only on documents prior to 1930 and may refer to a close relative, especially the Slender Danios, which we will discuss later. Likewise, Sri Lanka's old case remains highly suspect and unconfirmed. 

Zebrafish have been introduced to California, Connecticut, Florida and New Mexico in the United States, possibly by intentional stocking in aquariums or escapes from fish farms. The New Mexico population went extinct in 2003 and the latest published documents date back decades, so it's unclear if other species survived. Elsewhere, the species has been introduced in Colombia and Malaysia.

Habitat and the Distribution of the Zebra Danio Fish

Slender danios grow naturally in South and Southeast Asia. Habitats range from fast-moving currents to calm puddles. In recent years, many new species have been discovered in remote areas of Myanmar (Burma) and brought into the hobby. 

Zebra Danio can be found in a variety of habitats, from slow-flowing rivers and streams in the dry season to flooded ponds/swamps and rice fields during the monsoon season. 

Their habitat consists of rice paddies with a vegetation-rich alluvial bottom. They can also occupy hilly areas with rocky bottoms and tree branches. 

As in all countries of the northern hemisphere, light levels decrease during winter. It gradually increases from spring to summer and can be exposed to more than 12 hours of sunshine. 

Behaviour of the Zebra Danio Fish

Zebrafish are a relatively social species and exhibit gregarious behaviour. These herds may have a hierarchical dominance system established by playful, non-aggressive behaviour. They are sociable and peaceful fish, but you can see them chasing each other around the aquarium. 

They can be aggressive towards long-finned fish, they move slowly and can often be seen biting their fins. Being local fish, they do not work alone as they can cause stress and lead to disease. It can also cause them to become inactive and choose to spend time in hiding. 

Diet of the Zebra Danio Fish

Zebrafish are not too demanding when it comes to food. Natural omnivores, these freshwater fish prey on all forms of food that can be found in nature. From plant debris to unfortunate little insects that enter the water, they will eat everything! Luckily for us, captive Zebra Danio has the same flexible diet. 

The easiest way to satisfy your cravings is to use over-the-counter foods. Flakes and granules can provide a nutritionally balanced diet that meets their dietary needs.

Reproduction and Life Cycle of the Zebra Danio Fish

Reproduction of zebrafish is a fairly simple process. They spawn relatively often and can lay more than 400 eggs at a time! 

Not only that, but they also breed in pairs with the same mate. It is a peculiar habit rarely observed in the fish kingdom. Once matching pairs are split by death or physical separation, they usually stop spawning! 

The best way to breed a Danio Zebra is to let you form the wild. Group some young fish into large groups. They will eventually be paired, which will make spawning easier.

To lay eggs, install a separate laying tank. Unfortunately, Zebra Danio does not show any parenting behaviour. Adults try to eat the eggs immediately after birth.

1. The Life Span of the Zebra Fish:

The typical lifespan of a zebrafish is 2 to 5 years. There is no guarantee of life. Like other pets, the lifespan of the Zebra Danio depends largely on the level of care provided. 

People with perfect living conditions who are on a super diet are more likely to live closer to the five-year norm. However, fish in poorly maintained aquariums are at greater risk for disease and premature death.

2. The Types of Zebra Danio Fish:

There are many varieties of zebra danio fish available in the market. These have mutants with vibrant colours such as green zebra danio fish, golden zebra danio fish, red zebra fish,  blue zebra fish, etc. the following are the known varieties of the zebrafish:

• Golden Zebra Danio: 

This is a unique variable zebrafish. It is quite small, but it is quite noticeable. It has the usual dark blue stripes of the zebrafish, but it reproduces quite well and is decorated with yellow and white stripes.

• Dwarf Spotted Danio:

This danios is smaller than a zebra and rarely grows more than an inch and a half, making it suitable for small aquariums. 

Dwarf spotted danios are really beautiful with the combined look of several species of danios. Fine dorsal scale meshes with stripes, dots, and light grey.

• Giant Danio: 

The Giant Danio can grow up to 1.5 inches long, making it one of the tallest and thinnest danio species. It has a blue and yellow torpedo body with grey and clear fins.  If danios are capable of aggression, the giant danios are the obvious culprit.

• Pearl Danio: 

Pearls grow up to 2 inches long and live up to 5 years. This is significantly longer than Danio's three-year average. The body of the fish is yellow-brown, pink or silvery with two bands ranging from light yellow to white or blue to red. Female Slender Danios Jade pulls a pair of dumbbells.

• Rosy Danio: 

At first glance, the colour pink looks like the Danio pearl, but without the yellow stripes on the sides. It is usually pinkish-pink along the lower body and lower fins, emitting bluish-purplish light. Pink Danio is also known as Passion Violet Danio.

Conclusion

• Zebrafish was initially thought to be native to a larger area, extending to Myanmar in the east and Pakistan in the west. However, the current consensus is that the species is native to a much narrower range in parts of India and Bangladesh. 

• Part of this distribution change is due to the identification of a similar species that was once confused with Slender danios. Wild zebrafish use a wide variety of habitats, from fast currents to slow, near-stagnant ponds (zebrafish freshwater fish), but environmental destruction reduces their living space.

• Zebras breed easily and economically, which is why the zebra danio available in the aquarium industry today is almost always kept in captivity. Commercial farming has provided a large and unlimited supply of this species, but it has also resulted in the fish being less hardy than native wild species.
