Market price:
The price of silver arowana is about 50 to 500 yuan each, but prices vary depending on size, purchase region, and so on. For example, in some more remote areas, because silver arowana are scarce, the price is slightly higher than in developed areas. At the same time, prices vary greatly with the size of the silver arowana: for example, around 20 cm usually ranges from 50 to 70 yuan, around 35 cm ranges from 90 to 100 yuan, 50 cm ranges from 150 to 250 yuan, and 60 cm ranges from 300 to 500 yuan.
What does it eat?
Arowana are carnivorous animals, and the diet of most arowana includes frogs, loaches, crickets, goldfish, grasshoppers, small shrimp, and so on. It can be said that silver arowana eat a very mixed diet and can be fed cockroaches, though it is best not to catch them directly from home; buy ones that have been processed at the fish market. You can also feed small fish, fish worms, and similar things. As for “eating cockroaches can turn it into a golden arowana”, that is nonsense; the golden arowana and the silver arowana are two different kinds of fish. If you want the silver arowana to grow well and have good color, you can feed live shrimp, and you can also feed fresh small scaled fish fry. If you feed scaleless fish such as loaches for a long time, it will cause the back to become black and dark.
What do silver arowana over 20 cm eat?
Silver arowana over 20 cm have already grown a lot by this time, and the body's various immunities have also improved. What the silver arowana eats becomes even more important at this stage. Feeding tips for silver arowana over 20 cm:
1. You can feed some larger raw fish and shrimp bait.
2. You can appropriately feed loaches, insects, and so on. But note that when feeding loaches, because the dragon is not very big yet, you must cut the loaches into small pieces. As for insects such as cockroaches, you must make sure they do not carry bacteria.
3. You can feed live bait. Live bait often carries bacteria on its body. When fed to arowana, it can easily cause infection in the arowana, and it can very easily cause the silver arowana's barbels to break. So it is not recommended to feed live bait often.
4. The amount fed should still follow the principle of small meals more often.
What is good to feed small silver arowana around 15 cm?
Small arowana around 15 cm can be fed normal breadworms and small shrimp (it is best to remove the shrimp sword from small shrimp), and can also be fed 1.5 cm small fish. At this time the silver arowana grows very fast and naturally can eat a lot. Feeding tips for silver arowana over 15 cm:
1. Besides feeding some small river shrimp, you can appropriately feed 1.5 cm to 2.0 cm rosy barbs and small tiger barbs.
2. Appropriately increase the number of feedings and the amount. Mainly aim for seven-tenths full. Each time you feed, observe the little dragon. If its belly is somewhat bulging and it is not eating very quickly, that means the silver arowana is full. As the dragon's owner, you must observe it carefully, do not let it go hungry and do not let it eat too much, and develop the habit of small meals more often from a young age.
What is good to feed juvenile silver arowana under 12 cm?
Juvenile fish under 12 cm have just begun eating raw bait. At this time you can feed freshly molted white breadworms, small shrimp (be sure to remove the heads and tails, and it is best to peel them into shrimp balls to feed, so that the hard shells do not injure their stomach and intestines), bloodworms, and other relatively palatable baits. Feeding tips for silver arowana over 12 cm:
1. Feeding breadworms often will make the silver dragon become picky, so it is recommended to feed breadworms only occasionally.
2. Because the silver arowana is still small, and the hard shells of small river shrimp can easily injure its stomach and intestines, you must remove the heads and tails of the small shrimp before feeding.
3. Number of feedings. Feed small meals more often, which is good for the digestion of juvenile fish. You can feed four times a day.
How many are good to keep?
1. This depends on the size of the fish tank. The size of the fish tank directly determines the density of the fish, and the size of the filter, to ensure that the fish in the tank can move freely. The size of the fish tank must be suitable, not too small. Therefore, how to keep silver arowana is related to the size of the silver arowana and the fish tank.
2. Keep dragons not in pairs. Keep fish only in odd numbers, so that the dragons in the tank restrain each other and avoid fights caused by sneak attacks from a third party. If you start mixed keeping from silver arowana fry in even numbers, aside from feng shui, just considering mixed keeping is also possible, but if you suddenly switch to even-number mixed keeping partway through, fights can easily occur.
3. This fish is too powerful. If the number is even, one of them will be overwhelmed. With an odd number, they will restrain each other, can survive, and avoid fights.
Keeping tips:
1. Fish tank preparation: The silver arowana is a large fish, so the fish tank should be at least 1.5 m long, 0.5 m wide, and 0.7 m high. At the same time, the fish tank must have a cover, because the silver arowana is a fish that swims in the upper layer and likes to jump, so as to avoid it jumping out of the tank when no one is around and dying of suffocation.
2. New fish entering the tank: When a new fish has just been bought back, the fish tank must thoroughly eliminate the chlorine in the water. If conditions permit, it is best to take water from the new fish's original tank back to your own fish tank, and taking back 1/3 is best, to help the new fish with adverse reactions to sudden environmental changes.
3. Bait feeding and food training: Newly introduced small silver arowana fry should start food training from the 2nd day. You can use live bloodworms (first soak them in an aqueous solution of 3% table salt and 5 g/L furazolidone for 15 minutes before feeding). Be very careful during operation, and feed until they finish eating within 20 minutes.
4. Changing food at the right time: Silver arowana fry are mainly fed live bloodworms within 10 days of age. After 10 days of age, switch to quick-frozen bloodworms. In the 3rd month, gradually transition to shrimp. In the 1st month, feed 5 times a day in total, in the 2nd month 4 times, in the 3rd month 3 times, and in the 4th month 2 times.
5. Adjusting density: Silver arowana grow relatively fast, so density must be adjusted according to growth conditions. It is best to sort once every 1 month. The first time, stock 150 fish per tank, the second time 70 fish per tank, the third time 25 fish per tank, and afterward gradually reduce the stocking number.
6. Water quality management: Silver arowana are suited to living in weakly acidic water. Be sure to keep the water pH between 6.5 and 7.5, change the water once every three days, changing one third or one fourth each time, and at the same time regularly clean filter materials such as filter cotton and white cotton.
