How to raise arowana?

Silver arowana fish body is like a metal silver, which contains cobalt blue, blue, cyan and other mixed colors, shining, very noble, as if the fish aristocracy, fascinating. How much do you know about silver arowana? Do you know how to raise arowana correctly? Here is a comprehensive introduction to how to raise silver arowana:

Silver arowana new fish into the tank

1. When the new silver arowana is bought back, the air pump in the fish tank has to run for at least 24 hours to completely eradicate chlorine in the water. If you always use a biofilter, it is best to have the water reach a pH of 6-7 and a temperature of 25 degrees Celsius.

2. Add small salt to the fish tank (approximately 1 or 2 teaspoons to every 5 gallons or 20 liters of water) to reduce the risk of fungal attacks and make the fish healthy and boost its appetite.

3. If there are conditions, it is best to get water from the original tank of the new fish to return to your own tank (if there is no problem with the water in the original tank), and it is best to take back 1 stroke 3, so as to facilitate the adverse reactions of the new fish to sudden changes in the environment. It is recommended that arowana be raised from an early age.

4. Because the arowana is a large fish, the fish tank is at least 1.5 meters long, 0.5 meters wide and 0.7 meters high. Fish tank must be capped, arowana belongs to the upper swimming fish, like to jump, in order to avoid no one jumped out of the tank and suffocated to death.

It is suggested that the silver arowana has a strong physique, rapid growth and large food intake. Strong temperament, can swallow small fish, should not be mixed with other fish.

Daily feeding of silver arowana

1. Change water: change water at least 20% Mur30% per week, do not make sudden changes in temperature and PH value, such as sudden changes will lead to the sudden death of arowana. Be careful when changing water to avoid being frightened by arowana. And when raising arowana, we must avoid completely replacing it with new water, otherwise it will cause harm to the fish. If you see arowana fins and scales fall off, it is caused by too much water change, you can pause the change of water, they will recover naturally. However, the amount of water exchange should not be too small, too little will make the fins opaque and serious eyeball opacity will cause the cheek cover to flip.

2. Lighting: red arowana needs a lot of light, preferably up to 4 hours a day. Other arowana are also best able to achieve 8 hours of light. Some fish farmers, such as red arowana, like to use red light to illuminate red arowana, so as to achieve better results. The best light for arowana is daylight, and long-term use of light will cover the back of the arowana.

3. Filtration: the juvenile arowana is too large to be raised in a grass tank. The problem of large fish tank filtration is more prominent. The filtration systems suitable for arowana culture mainly include upper filter, external filter, upper + pumping sand layer filter and overflow filter. But it should be noted that when arranging the arowana box, you should consider setting up a lifting motor (surf pump), which has great benefits: first, it can form a strong current, second, increase the amount of dissolved oxygen in the water, third, more importantly, it can maintain a certain amount of exercise to maintain the beautiful shape of the fish. Fourth, it is also very important to prevent the arowana from turning its gills, which can be trimmed when the gills are turned. The use of a water-lifting motor during recovery can smooth the growing gills.

Feed management of silver arowana

1. The arowana will hit an angle in the tank when eating too hard, which will lead to injury. When feeding, it is best to feed in the middle of the tank. Arowana is a fleshy animal, most of the arowana diet is frog, Loach, cricket, goldfish, grasshopper, shrimp and so on.

2. There is a problem of adding color to the feeding, such as the red dragon. Feeding the red arrow or shrimp plays a certain role in increasing the color of the red dragon, because the red arrow and shrimp contain red pigment.

Young fish less than 3 or 12 centimeters have just begun to eat raw bait, then you can feed white bread worms, shrimps (be sure to turn around and feed them into hard shells so as not to hurt their intestines and stomach), blood worms and other more palatable bait. Eat less and eat more and feed four times a day.

4, 15 cm of crayfish can be fed with normal bread worms and shrimps (shrimp preferably removed from the shrimp sword), or 1.5 cm of small fish. At this time, the arowana grows rapidly and eats an astonishing amount. The feeding times and amount can be increased appropriately.

5, more than 20 centimeters of arowana can be fed with larger fish, shrimp, Loach, meat and other bait. Can also feed a variety of insects and other live bait, these are arowana's favorite food, but be careful not to let these baits be contaminated.

In addition, the viscera, especially the liver is not suitable to feed arowana, its more fat will cause arowana disease. Goldfish is not a good bait in live bait. Artificial bait is best to use less fat beef, of course, you can also buy the finished arowana special bait.

Common diseases of silver arowana

1. Ptosis

Caused by long-term feeding of bottom food, it will be restored if it is put back into the pond. Cover the fish tank with opaque black paper, add a white light to the top of the fish tank, feed the top food or place an object on the top of the fish tank to attract the attention of the silver arowana, and remove the black paper after 3 months.

2. Gill turning disease

Due to the unclean water quality, insufficient space and insufficient dissolved oxygen, the water temperature changes suddenly. At the beginning of the disease, you will see the irregular movement of the gills, shortness of breath, the pial membrane on the operculum facing outward rather than inward, and the red gills can be seen. Change the water quality as soon as possible, provide more oxygen, fish Gill will change from soft to hard, there is no choice but to carry out surgery.

[surgery requires] scissors, gloves, sterilized alcohol, clean and damp cloth, anesthetic.

[method of operation] find a clean plastic pocket, put water in the pocket, put the arowana in the pocket, add anesthetic to the water in the pocket, wait for the anesthetic to work, take the arowana out of the pocket and put it on a clean and moist cloth and trim it with scissors (ensure disinfection), then put the arowana back into the tank, increase the dissolved oxygen, let the arowana rest and let it rest in dim conditions when the arowana regains consciousness. If the silver arowana is not interested in food, change 20% of the water every day, change the quality of the water for 6 days, and increase salt to reduce the risk of parasite attacks.

3. White spot disease

Caused by a phylum of parasitic protozoa, some or most of the silver arowana is covered with white dots. It mainly affects the fins and reduces the arowana's appetite, and the silver arowana can often be seen rubbing against the body. Raise the temperature to 30 or even 34 degrees Celsius and add 3% small salt. If not, you have to be treated in a medicine tank alone. The main symptom is that the whole body of the diseased fish is covered with white spots, like white powder, and in severe cases, it is like covering the fish with a milky white film. The cause of the disease is caused by the parasitism of small melon insects on fish. Main prevention and control measures:

① was sprinkled all over the pool with 0.1~0.2ppm mercurous nitrate.

② was sprinkled with 500ppm copper sulfate and 500ppm magnesium sulfate all over the pool.
