The light intensity in the feeding environment directly affects the color reaction of arowana. If the light in the arowana culture environment is strong, the pigment cells of arowana will stretch, and once the pigment cells of arowana stretch, the pigment will expand with the cells. After the area of pigment cells in Arowana increases, the color of its body and scales will also be obviously deepened, for example, the parts with more red pigment will become redder. If you raise arowana, you usually need proper red light irradiation, which is very beneficial to the body color development of arowana. However, attention should also be paid to controlling the light intensity irradiated by arowana. Too strong light is not enough.
On the contrary, if the feeding environment of arowana is dark, the pigment cells on arowana will shrink and the pigment molecules will become smaller, and the color of arowana will also fade. At the same time, the pigment on arowana will gradually change into several kinds with the contraction of cells, and sometimes even shrink into small spots, which will lead to the color fading of other parts of the body.
Generally speaking, the normal growth of arowana needs enough light, and it is necessary to keep arowana getting 4~8 hours of light every day. The healthy growth of arowana can not be ignored.
Second, the scientific breeding method of arowana
1, insist on changing water every week. It is necessary for arowana to change water once a week. Pay attention to prepare the water to be changed in advance. Fresh water to be added should be dried 1~2 days in advance to remove chlorine from tap water before it can be used to raise arowana. And in the process of changing water, it is necessary to keep the temperature of new water consistent with that of old water with PH value, so as not to bring discomfort to arowana. In addition, the water change can not be completed at one time, and 20%-30% of the water in the fish tank can be changed at one time, so as to prevent the arowana from getting sick or even dying because of the great changes in the feeding environment. When changing water, first extract a proper amount of old water, and then slowly inject new water along the wall of the fish tank.
2. If the sunshine is insufficient, the breeder can install appropriate fluorescent sticks above the fish tank to make up for the lack of sunshine. However, it is worth noting that the most suitable light for the growth of arowana is sunlight, so try to give arowana sunlight.
3. Ensure that the feed of arowana is fresh and delicious. Active feed is most beneficial to the growth and development of arowana. So it is best to use some active foods, such as earthworms, loach, small fish and shrimp, cockroaches and so on. Feed arowana until 7 minutes full every time. If you accidentally feed too much, you must fish out the leftover feed in time to avoid polluting the water quality.
4. Keep the water quality good. In addition to changing water regularly, breeders should also clean the aquarium regularly to maintain good water quality. It is suggested that an appropriate filtration system should be installed in the aquarium, or the aquarium should be cleaned and disinfected regularly.
5, regular quantitative feeding. For young arowana, some small breadworms and blood worms can be used to feed them; For adult arowana, you can feed some meat, shrimp and other foods. Of course, we should also keep the variety of arowana feed.
This concludes the introduction of Dr. Paw Paw. Finally, remind the breeder that when the arowana is found to be abnormal or sick, it must be treated in time, and it should not be taken lightly, so as not to aggravate the condition of arowana and cause more serious consequences.
