How much does a 10cm silver arowana fry cost per fish? How do you raise it?
The silver arowana, also called the two-whiskered bony-tongue fish, is a relatively popular ornamental fish. Its body is very slender and rather thin, and its mouth sits at the very top, opening very wide, even reaching behind the eyes. As a carnivorous fish it is fairly fierce, often leaping up to catch prey, and it does not even spare dragonflies, mantises and the like on branches above the water surface. Below let us take a look together at how much a 10cm silver arowana fry costs per fish? How do you raise it?
1. How much does a 10cm silver arowana fry cost per fish?
A 10cm silver arowana fry costs around 50 yuan per fish, though this refers to the wholesale price; if bought individually it would cost more than that. Of course, there are also ones at 20-30 yuan each, but the survival rate of those bought is not high and they are hard to keep alive. Of course, the price of silver arowana fry still differs somewhat from region to region and cannot be generalised, so this is just for your reference.
Silver arowana fry are not cheap, and to improve the survival rate it is advisable to buy from a proper fry market, because the measures in all respects there are more complete, and if the ones bought are healthy they are also easier to raise. If the fry being kept in the early stage show signs such as slow reactions, not being alert to the environment, dull eyes, wounds on the body, or poor water quality, then do not buy them; everyone must observe carefully.
2. How do you raise silver arowana fry?
The silver arowana is one of the easier ornamental fish to keep. Below let us look at the specific raising methods.
1. Rearing environment
If silver arowana fry are to grow healthily, the water temperature must be controlled between 27 and 28 degrees Celsius, and neither chlorine nor nitrite may be detectable in the water.
The quality of the water is the key factor; if the water has been polluted, then it definitely cannot be kept alive. If signs of illness appear, you can immediately treat it with a medicinal bath, and observe promptly to see whether any other fish have been infected.
2. Feeding
When silver arowana fry first start eating bait, it is advisable to feed headless small shrimp, white mealworms, bloodworms and so on. Remember the feeding principle of small meals more often; only in this way will they gradually adapt.
Adult silver arowanas can usually be fed small fish and shrimp, loaches, frogs and so on as food, but you must pay attention to the amount fed. Although they have a large appetite, it is still limited; if there is too much food residue in the water it will cause them to fall ill.
When eating, they can easily bump into the fish tank while chasing and snatching food, so when feeding, place the food in the middle of the tank to reduce the chance of injury.
3. Disease prevention and control
During the raising of silver arowanas, drooping eyeballs, white spot disease and gill-curling disease very easily occur. The symptoms of these diseases must be understood in advance and treated with the right medicine, because once ill, if treatment is not timely it very easily causes death.
A friendly reminder: if you have just bought silver arowana fry, in order to help them adapt to the environment as quickly as possible you can take the original water and put it in the new fish tank, on the premise that the water quality has not been polluted.
