New fish in the fish tank
For newly bought fish, the air pump in the fish tank must run for at least 24 hours to completely eradicate chlorine in the water. If the biofilter is used all the time, it is best to make the water reach PH 6-7 and the water temperature is 25 degrees Celsius. Add a small amount of salt (about 1 or 2 teaspoons in every 5 gallons or 20 liters of water) to the fish tank to reduce the risk of fungal attack, make the fish healthy and stimulate the appetite. If possible, it is best to take the water from the original tank of the new fish back to its aquarium (if there is no problem with the water in the original tank), and it is best to take it back to 1/3, which is conducive to the adverse reaction of the new fish to environmental mutation. It is recommended to raise arowana from an early age.
Current management
Change at least 20%-30% water every week, and the ammonia content shall not exceed 0. 1 ppm (mg/ 1). Don't let the temperature and pH suddenly change, if the change suddenly leads to sudden death of arowana. Check the PH value and other toxic substances every week to avoid countermeasures. Be careful when changing water, so as not to scare arowana. Moreover, keeping arowana must avoid completely changing to new water, otherwise it will cause harm to the fish. If you see the fins and scales of arowana fall off, it is caused by too much water change. You can stop changing the water, and they will recover naturally. However, the amount of water exchanged should not be too small. Too little will make the fins opaque and the eyeballs turbid, leading to gills turning over.
Fish tank size
Because arowana is a large fish, the fish tank is at least 1.5m long, 0.5m wide and 0.7m high. The fish tank must be covered. Arowana belongs to the upstream fish and likes to jump, so as to avoid choking when no one jumps out of the tank.
Water quality [1]
Breeding of arowana (3) The survival of arowana needs weak acid to neutral water quality, and the hardness needs soft water. Because arowana has strong adaptability, there is no problem with tap water in general, but if you want the arowana you bought at a high price to live comfortably, you should give it proper water quality. Specifically, the DH value of 3- 12 is ideal between pH 6.5 and 7.5. Generally speaking, the water temperature is 24-28 degrees Celsius, and it is best to keep the water temperature of Yinlong and Black Dragon at 27-28 degrees Celsius. The nitrite content and chlorine content are preferably zero. Water should be fully aerated and softened before it is used to raise arowana.

illuminate
Arowana needs a lot of light, and it is best to have 4 hours of light every day. Other arowana also had better reach 8 hours of light. Some people who love fish, such as those who keep red fish, like to irradiate red fish with red light to achieve better results. The best light for arowana is daylight. Long-term use of light will darken the back of arowana.
filter
Young arowana is too big to be kept in a water plant box. As big as a fish tank, the problem of filtration is more prominent. The filtration systems suitable for arowana culture mainly include upper filter, outer filter, upper+sand pumping filter and overflow filter. However, it should be noted that when arranging the arowana box, you should consider arranging a water pump (surf pump), which has great benefits: first, it can form a strong water flow; Secondly, it can increase dissolved oxygen in water; Third, more importantly, arowana can keep a certain amount of exercise and keep the graceful figure of the fish; Fourth, it is also very important to avoid arowana turning over its cheeks, so that it can be trimmed and restored when it happens.
fodder
Arowana will bump into a certain angle in the tank if it eats too hard, which will lead to injury. It is best to feed in the middle of the fish tank when feeding.
Arowana is a carnivore, and its recipes are mostly frogs, loaches, crickets, goldfish, grasshoppers and shrimps. There is a problem of adding color in breeding, such as red dragon. Feeding red arrow or shrimp will add color to the red dragon, because both red arrow and shrimp contain red pigment. Young fish under 12 cm just started to eat raw bait, and they can be fed with palatable bait such as white bread worm and shrimp (the head and tail must be removed, and it is best to peel them into shrimp balls to avoid hard shell injury to the stomach) and blood worm. Eat less and eat more meals, four times a day. The arowana around 1.5 cm can be fed with normal breadworms and shrimps (shrimps should be removed from the shrimp sword), or with small fish around 1.5 cm. At this time, arowana grows rapidly and eats an amazing amount. The feeding times and the feeding amount can be appropriately increased. Arowana above 20 cm can be fed with larger bait such as fish, shrimp, loach and meat. You can also feed live baits such as various insects, which are arowana's favorite food, but be careful not to pollute these baits. In addition, the internal organs, especially the liver, are not suitable for feeding arowana, and too much fat will cause arowana disease. Goldfish is not a good bait in live bait. Studies have shown that almost all infectious diseases or parasites infected by arowana, which eats goldfish exclusively, are infected by goldfish when they are kept in small fish tanks. It is best to use beef with less fat as artificial bait. Of course, you can buy special bait for arowana if you have the conditions. However, arowana will be unaccustomed to artificial feed at first, and it needs artificial bait training.
Breeding skills
Arowana has strong physique, rapid growth and large appetite. Fierce temperament, can swallow small fish, not mixed with other fish. Stop using large fish tanks, cover them, and don't lay sand on the bottom. I like weak acid or neutral soft water, the water temperature is above 22℃, and 24-28℃ is the most suitable. Mainly feed on animal bait.
