Zebra fish (Danio rerio) in the aquarium, our advice to take care of this type of fish




The zebrafish (Danio rerio) is a small animal that is very easy to raise in an aquarium. Indeed, it is sociable, calm, tolerant, and simple to reproduce, which is ideal for beginning audiophiles. He gets along very well with many other peaceful species, making him a good candidate for a community aquarium. In addition, it is a popular and model fish in the scientific world, particularly because of its impressive regenerative abilities.

Who is the zebrafish?


Zebrafish (Danio rerio) is a small fish native to India. Very appreciated in audiophilia, it is easy to raise, it is very tolerant, it is simple to reproduce and it is very pretty with its stripes that recall the zebra. There are several varieties of Danio fish, including the Danio leopard, which often competes with zebrafish.

This small fish, which is cheap to buy, has a strong gregarious instinct and will need to live among a minimum of 8 to 10 individuals. In addition, it gets along well with most other species, being peaceful and sociable.


In nature, it can live up to 5 years and exceed 6 cm in length. But in an aquarium, it lives only 3 to 5 years and is only 4 cm long. The zebrafish shall have a bluish body covered by small horizontal strips; males are golden in color. It is conical in shape, but the body of the female is more rounded and wider than that of the male. Each has a pair of small barbs on each side of the mouth.


For the record, the zebrafish is the first vertebrate organism to be cloned and is known for its great regenerative abilities. The species was widely described in the rivers bordering the Ganges, notably by zoologist Francis Buchanan Hamilton in 1822, as Cyprinus rerio. Today, the animal is very present in the United States, either because of voluntary implantation or because it escaped from farms. It was not imported into France until 1905.


The behavior of the zebrafish


As a gregarious, it is always advisable to buy a bank of zebrafish for at least 10 individuals. If you need to complete your bench, buy at least 5 to help integrate the new ones; this is preferable to individual "replacement".


Being peaceful and sociable, zebrafish are understood to include all species that are not aggressive. He especially likes Guppys, but also shrimps and snails. However, avoid placing it in a bin that is used to accommodate large or agitated fish species, as it may be hunted, which causes stress and makes fish that get sick more fragile.


Zebrafish fish breeding


It is relatively easy to reproduce the zebrafish in an aquarium, as long as it is placed in a small suitable tank. Cover the bottom with glass or clay beads to protect the eggs, as parents may eat them. Lighten the tank well for 14 hours each day to encourage spawning, which is a natural condition for future parents. Also, bring live food, as it encourages reproduction, like plants, true or false.


Place two males in the box for a female (the female is recognizable by its rounded belly) and preferably remove the parents as soon as the egg is laid. The female lays 300 to 400 eggs and lays them on the leaves of the plants. The eggs hatch after 2 days of incubation if the water is above 28°C and 3 days if it is at 26°C.


The nascent larvae measure 3 mm and are immediately able to swim and feed on their own. Curiously, all fry are female. Generally, the youngest children turn into males after 5-7 weeks depending on the heat of the water and the amount of food available. Males can reproduce after 3 months of life, once their gonads are formed.


How to raise zebrafish in an aquarium?


The zebrafish aquarium


The zebrafish is a very resistant, hardy, and highly tolerant fish in an aquarium, making it very attractive to beginning audiophiles.


It supports water with a pH between 6 and 8 and is not really concerned about the hardness of the water, although it is recommended to keep it at a high between 10 and 20.


In its natural environment, the temperature of the water varies from 24 to 38°C depending on the season and falls in winter, which is why it is recommended to maintain the aquarium temperature between 18 and 25°C.


Allow a minimum of 80 liters for a school of 10 fish. The zebrafish can be placed in a community tank, but only with calm species of its size.


The diet of zebrafish


The zebrafish has a superior mouth, i.e. upward, meaning that it feeds on the surface by catching its prey. So you can give it glitter without any problems, as well as all kinds of freeze-dried foods.


However, zebrafish are carnivorous fish that love to feed on live insects, but also on larvae, mud worms, and small crustaceans.
