What foods zebrafish like to eat. What zebrafish eat

Zebrafish feeding.

Food preparation. Zebrafish have different food requirements at different stages of development, and the main food preparation is divided into two parts: harvest insects and paramecium.

1) Hatching of harvest insects.

1) Incubation equipment:

Incubator: The incubator used to hatch the eggs is a conical plastic product. The diameter of the cylindrical part is 60 cm, the height is 50 cm, and the height of the garden cone part is 30 cm. A valve is installed at the bottom of the garden cone, through which the hatched harvest insects and impurities and egg shells can be separated.

Aeration device: Depending on the size of the aeration head and the volume of the incubator, place 1-3 aeration heads at the bottom of the incubator cone to ensure that the dissolved oxygen in the water is above 6mg l during the hatching process of the eggs in the harvest year, otherwise the hatching rate of the eggs will be affected.

2) Water for hatching:

The water quality of the water used for the hatching of insect eggs in the harvest year should be good, and only salt needs to be added, and no other elements need to be added. The brine concentration is 15 18. Clean the incubator and inject fresh water to a distance of 10cm from the upper mouth.

Then put in the coarse salt in proportion, turn on the aeration switch for aeration, so that the salt dissolves.

3) Incubation Method:

Incubation density: 2-3g of eggs per liter of water.

Incubation water temperature: control at about 30, the hatching time of harvest insects is generally 18-24 hours.

Purification treatment of harvest insects: take out the aeration head, wait for a while to open the valve under the incubator, first release the impurities, and then release the harvest insects, and close the valve immediately when you see the egg membrane. The valve outlet is placed in a 180-mesh sieve silk water filter bag.

After the harvest insects are filtered out, rinse the harvest insects in the bag with fresh water until the water is drained out. After the harvest insects are removed, they should be fed in time to improve the vitality and survival rate of the harvest insects, and if you need to wait, you need to add 12 saline and put the aeration head into the aeration head for re-aeration. Because the harvest insects can only survive in high salt concentrations.

4) Disinfection of harvest insects:

Formaldehyde solution is added to the incubator one hour before harvest to disinfect the insects, so that the formaldehyde concentration in the water body is 50ppm, which mainly kills parasites (such as polyconstriction worms, etc.) and pathogenic bacteria. Chloramphenicol can also be sterilized by adding chloramphenicol to a concentration of 20 ppm half an hour before harvesting.

Juveniles aged 2 to 5 days can be fed with newly hatched harvest worms (imported harvest worms with an incubation time of about 15-18 hours), and 6-20 day old juveniles can be fed domestic harvest worms that have hatched for about 20 24 hours (such as aged harvest eggs, the hatching time can be extended to about 30 hours).

6) Notes:

The eggs of the harvest worms placed in the cold storage should be raised 2-5 days in advance and placed indoors to allow them to naturally warm up to room temperature for activation. The warmed harvest insects should not be put into cold storage, such as repeated heating and cooling, which will affect their hatching rate.

When the insects hatch, electric lights need to be installed above the incubators, generally 2 incubators with a 60-watt electric lamp. Lights need to be turned on during the day and at night.

Try not to suck the shrimp shells when feeding, especially when feeding small fish, which can cause intestinal obstruction in small fish.

Yellow plastic bag, dolphin brand tropical fish food microparticles, this I bought 2 pieces a pack, 5 fast three packs, fish babies like to eat, if the zebra is too small can feed the fish fish opening food, is a very small shrimp eggs, you ask the fish shop people and he will tell you.

Zebrafish food:

1. Red line ruler to prepare insects: red line worms have extremely high nutritional value, and they should be rinsed repeatedly in clean water before feeding, which is the main ingredient of zebrafish.

2. Lean meat: Lean meat is rich in protein, fat and various inorganic salts, which can ensure the normal growth and consumption of zebrafish.

3. Daphnia: Daphnia is nutritious, easy to digest, and has a strong ability to reproduce and colonize.

4. Tropical fish feed: zebrafish are small in size, and floating granular powder feed is easy to feed.

Feed, zebrafish can eat some insects, shrimp, fish and other feed, it is recommended to choose a good float feed when buying, so that it can be eaten; Omnivorous, zebrafish can eat some ham crumbs, shrimp meat and the like, there are no strict requirements for food, almost most of the food can be eaten; Fresh vegetables, vegetables are rich in vitamins, which can replenish nutrition and protect the stomach and intestines after eating.

Zebrafish can eat a variety of feeds such as fish worms, earthworms, cilia, mealworms, small live fish and frozen bloodworms, which are rich in nutrients to supplement its daily needs. It is recommended that breeders choose floating feed when buying feed, and zebrafish generally do not like to eat and cannot eat the feed that sinks to the bottom.

In addition to feed, zebrafish also eat various omnivores such as daphnia, mosquitoes, ants, ham shavings, shrimp meat, etc., and they mainly feed feed. It does not have strict requirements for the food it eats, but it is important to ensure that the water is clean, as there is a high risk of zebrafish getting sick if the water is polluted.

It is recommended that breeders can feed some chopped fresh vegetables in moderation, such as spinach leaves, radish, cucumbers, etc. Vegetables contain a lot of vitamins and a variety of trace elements, which can play a role in supplementing nutrition, aiding digestion and protecting the stomach.

Zebrafish is a tropical stool fish that likes to live in groups and swim very fast. What zebrafish eatInsect insects, paramecium, nematodes, bloodworms (larvae of midges), daphnia (fish insects) or tropical fish feed can all be used as food for spotted round horsefish.

In general, zebrafish also have slightly different foods at different stages.

1. The food of juvenile fish that has just emerged is mainly paramecium.

2. Adult zebrafish, the food is mainly artemia, there are brine worm eggs sold on the market, and they can be fed to zebrafish when they hatch directly.

Zebrafish can eat fish insects, earthworms, ciliates, mealworms, small live fish, pellet feed, etc., it is an omnivorous ornamental fish, zebrafish has a strong appetite, rapid growth, it is not affected by external temperature changes, and is always maintained in a relatively stable state. Zebrafish eat fish insects, earthworms, cilia, mealworms, small live fish, pellet feed, etc., which is an omnivorous ornamental fish, and there are many things that can be eaten, and it is very important to have a healthy diet when raising.

The zebrafish has a strong appetite and grows rapidly, and it is not affected by changes in the outside temperature and is always maintained in a relatively stable state. In the process of zebrafish breeding, feeding is a very important link, the safest food is feed, the feed is best placed in a dry, cool place, not damp.

They can be fed 2-3 times a day. After each feeding, be careful not to let the feed remain in the water, which will affect the water quality.

Zebrafish have a mild temperament, lively and active, swim all the time, their requirements for water quality are not harsh, red zebrafish are suitable for living in neutral water with moderate pH, like new water, so the owner often replaces the water for them.

The suitable water temperature is between 21 and 26 degrees Celsius, but red zebrafish are both cold and heat tolerant, and can live in water temperatures as low as 15 degrees Celsius and as high as 40 degrees Celsius.

It is best to feed red zebrafish with a variety of feeds and nematodes, and occasionally live bait such as nematodes can be fed, but it is not recommended to feed more, because it is easy to develop their picky eating habits and cause them to stop eating feed.

Zebrafish eat shrimp, they are omnivorous fish, there are many types of food that can be eaten, and shrimp is a type of food they prefer. The nutrient content in shrimp is relatively rich and easy to digest, and astaxanthin also has the effect of increasing body color, so breeders can feed them more shrimp. However, due to their small size, they can only eat some small dried shrimps.

When they are bred in captivity, they can be fed some shelled shrimp. <

Zebrafish eat shrimp, they have a more mixed diet, and they will eat most of the food that tropical fish can eat. Shrimp is one of their favorite foods, because shrimp is not only easy to digest, but also rich in nutrients, so many breeders will feed shrimp food to ornamental fish. In addition, the astaxanthin in shrimp can also make the body color of zebrafish more vibrant.

Zebrafish are bred in captivity, and they can choose to be fed some shrimp food. Due to their small size, keepers cannot feed them too large shrimp and can only feed them small shrimp. If you have time, you can also feed them some shelled prawns or river prawns.

1. Animal feed: As mentioned above, zebrafish are omnivorous animals, so they can eat a wide variety of foods. When they are raised in captivity, they can be fed some earthworms, nematodes, mealworms, daphnia, etc.

These foods are rich in nutrients and easy to digest, making them ideal for feeding them as a staple food.

2. Plant feed: In addition to these animal feeds, breeders should also feed some plant feeds regularly, so as to ensure their nutritional balance. They can be fed with common vegetables, young leaves, fruits, and moss.

3. Synthetic feed: synthetic feed is also more suitable for feeding zebrafish, if there are conditions, it is recommended to choose zebrafish special feed to feed.
