What do zebrafish eat?

The natural diet of zebrafish is very diverse. Zebrafish eat small insects and their larvae that swim in the water. Also, zebrafish eat small seeds that fall from plants. Under the conditions of aquarium care, these fish are completely unpretentious in the diet. They eat live food, Frozen, and dry food. The first two food groups cannot fully meet the nutritional needs of zebrafish because they are not balanced and do not contain any useful vitamins in the right amount. Therefore, the best choice for feeding zebrafish is high-quality dry food.

It is worth noting that this zebrafish eats food preferentially from the surface. Anything that falls to the ground is usually excluded from their area of interest. Also, the food should be of the appropriate size, since the mouth opening of the zebrafish is very small.

A wide range of dry food from Tetra makes it easy to choose the right diet for feeding zebrafish. These fish prefer to feed on the water surface, so it is important that the food stays on the surface for a long time. Tetramin flakes food keeps perfectly on the water and then slowly begins to sink to the ground. It contains more than 40 types of carefully selected raw materials. It provides a complete diet for the daily diet of all kinds of ornamental fish. Supports healthy growth and vitality. In the prebiotics contained to improve the function of the gastrointestinal tract.

Alternatively, you can offer fish floating foods from the MicroFood series in the form of sticks or pellets. Their size is ideal for small zebrafish mouth. And due to the high buoyancy, the food remains in the upper layers of the water for a long time.

Due to the high digestibility of fish food, they produce less waste, which keeps the water clean for a long time.

Feed the fish several times a day with a portion of food that is eaten by them in a few minutes.

How to Care for Zebra Danios

Appearance

The size of a zebrafish in an aquarium is 3-6 cm. The body is elegant, elongated in length. Zebrafish likes to eat dry food. The main color of the body is light yellow, the body is covered with wide dark blue stripes that create a pattern similar to the color of a zebra. The fins are short, almost transparent, and may have a yellow margin. Men have a slimmer body, women have a much thicker belly. Each lip has a pair of whiskers that are usually pressed tightly so that they are invisible.

In addition to the natural color, there are other color variations. Pink Danio – different color stripes, they are bright pink fish.

Leopard Danio – has a speckled color that resembles the pattern of a known predator.

Danio rerio – became the first fish with an altered genotype that led to bright fluorescent shapes: pink, green, blue, and orange.

There are also veiled varieties, which are characterized by a strong fin development.

Habitat

Zebrafish comes from South Asian countries. The wide range of this species includes Pakistan, India, Nepal, and Bangladesh. This small and agile fish is found in almost all waters: rivers, streams, canals, ponds, and lakes. In nature, zebrafish eats small larvae and insects. The species is characterized by seasonal changes in the habitat. During the rainy season, adult zebrafish are ubiquitous in flooded rice fields and large puddles. Here they look for food and lay eggs. Once the rainy season ends, they prefer to return to large permanent reservoirs.

Care and maintenance

zebrafish are very robust ornamental fish, so they are often started by novice fish keepers. In fact, for the maintenance of a minimum herd of danios (5-6 pieces), an aquarium for 30 liters is sufficient. But the greater the volume, the more comfortable the danios feel. Fish are very mobile, prefer to swim in the upper part of the aquarium. You can jump out of the water, so it is advisable to cover the aquarium with a lid or cover glass.

Zebrafish love clean water, so you need to take care of proper filtration and organize adequate ventilation. It is desirable to provide good lighting, with suitable lamps, the fish will look brighter and more attractive.

Zebra danio feeding time

Optimal water values for the contents: t = 17-25°C, pH = 6.7-7.0, GH = 6-15.

Feed zebrafish with high-quality dry food. Regular water changes are required-25-30% of the total volume. Long-stemmed plants are planted at the edges of the aquarium, the rest of the room remains free for danios.

Under suitable conditions, the Danio-rerio can live 3-4 years.

Compatibility

Zebrafish is one of the most peaceful fish. It can be connected to almost all inhabitants of the aquarium, except those who consider it as a food object. Do not combine zebrafish with large cichlids, large goldfish, brocade catfish. Active tetra barbs are also not recommended to be held with danios, especially with veiled forms whose long fins are necessarily bitten off.

The best neighbors will be proportionally sociable species: neons, minors, tetras. It gets along well with angelfish, Xiphophorus, guppies. Even siamese fighting fish often do not notice the presence of zebrafish next to them the neighbors in the aquarium. Any peaceful catfish (corydoras, bristlenose pleco) is also a good choice to settle in an aquarium with zebrafish because their “food niches” are different: catfish are demersal species, and danios prefer to swim near the water surface.

Zebrafish

From the genus Danio, the suborder Brachydanio is distinguished-relatively small species. The most popular of them are striped Danio rerio, Danio roseus, Danio black. We have known them since 1950.

Slim, very mobile, small / 4-5 cm long / fish live in the reservoirs of Southeast Asia. You need spacious, elongated aquariums not densely planted with plant aquariums. Fish live in herds, in the upper and middle layers of the water, feed on all kinds of food, the composition of water/hardness, active reactions/ undemanding, love freshwater.

On the question of What do zebrafish eat I can say that it is better to feed with high-quality dry food that sits for a long time in the upper layer of water. Zebrafish has a Low-key coloring, but they are attractive and elegant. Along the body of the fish are dark and yellow narrow stripes that throw blue, the same color, and fins. The dorsal fin is yellowish. Men are fitter, lighter colored, women are fuller and duller. Zebrafish has two pairs of antennae. There is a form of it with unusually long and wide fins. This type of Danio looks graceful, especially when it is above water.

Breeding

Spawning of zebrafish is easy. The incentive for this is a low water level and replaces it with fresh and substrate of small-leaved plants – Hornwort, Cabomba and others.

In the spawning ground with a net above the ground and an air sprayer, pour well-separated water (60-80 mm above the net) and throw a few branches of plants, so that there is a clearing for mating games. A female and two males or two females and four males are brought to spawn. Increase the temperature to 26-28°C. producers are not fed.

New caviar is transparent, barely perceptible, the size of semolina. A female gives 60 to 500 eggs.

After the label, the producers are planted, the net is taken away and the air pump is left, the water temperature is lowered to 24°C.

Small fry is fed small “dust” or infusoria. After three days, small crustaceans are introduced into your diet.

After 7-10 days the female can be brought to spawn again.

Zebra Danios from Birth to Young Adults

Aquarium with zebrafish

The aquarium of the proposed type is more of a combination of fish and plants by geographical area. The main task of a fishkeeper is to find the most successful combination of fish by planting other species.

During the development of the aquarium, you can come to the optimal option by observing and selecting the desired species. Few types of aquariums meet these conditions more, and one of them, the most common, is available for beginners-with fish species such as zebrafish, fire barb, Corydoras, and Cloud Mountain minnow.

From plants, you can take Limnophila, Sagittaria platyphylla, Acorus, Ludwigia. Cover the soil with soil, but you can leave it clean and plant the plants in pots, preferably dark green or dark yellow, square. The aquarium should be equipped with a filter, ventilation, and lighting in the range of 40-60 watts. It is advisable to use fluorescent lamps of type LB together with an incandescent lamp of 25 W. Water hardness in the range of 10-12. Temperature Of 24-26°C.

Aquarium care is reduced to replace water (a quarter of the lower layers) two or three times a month. The Substitution takes place under the condition that the water in the aquarium is not cloudy regardless of the color. In the case of cloudiness, the substitution is stopped, the fish are not fed for three days, and the water is expected to clear. If the water does not lighten yet, it is completely replaced by a newly settled (three-quarters of the upper layers). Fish after the exchange of water are fed on the second day.

During the water change, no fish can be planted, so that the smallest amount of water remains in the aquarium, which would give you a quiet short stay. I hope you found out What do zebrafish eat and your pets will be happy.
