I. Effect of light on dragon fish
Light intensity in the rearing environment It directly affects the color reaction of dragon fish. If the light in the arowana breeding environment is strong, the pigment cells of the dragon fish will stretch, and once the pigment cells on the dragon fish are stretched, the pigment will expand with the cells. After the area of the pigment cells on the Arowana’s body expands, the color of its body and scales will also deepen significantly. For example, the color of the original red pigment will become more red and bright. If the red dragon fish is raised, it is usually necessary to expose it to an appropriate amount of red light, which is very beneficial to the body color development of the dragon fish. But also pay attention to control the intensity of the light irradiated by the dragon fish, too strong light is not acceptable.
On the contrary, if the light in the breeding environment of the dragon fish is dark, the pigment cells on the dragon fish shrink and the pigment molecules become smaller, and the color of the dragon fish also fades. At the same time, the pigments on the dragon fish will gradually change with the contraction of the cells, and sometimes even shrink into a small spot, which will cause the color of other parts of the body to become lighter.
In general, the normal growth of arowana requires sufficient light, and it is necessary to keep the arowana getting 4-8 hours of light every day. The main point is that the arowana grows healthily, which cannot be ignored.
Second, scientific feeding methods of dragon fish
1. Adhere to every Weekly water changes. It is necessary to change the water for the dragon fish once a week. Pay attention to prepare the water to be changed in advance. The new water used for adding should be dried in the sun for 1-2 days in advance to remove the chlorine element in the tap water before it can be used for feeding. Dragon fish. And in the process of changing the water, it is necessary to keep the temperature of the new water consistent with the PH value of the old water, so as not to cause discomfort to the dragon fish. In addition, each water change cannot be completed at one time, and 20%-30% of the water in the fish tank
can be replaced each time to prevent the arowana from getting sick or even dying due to major changes in the breeding environment. When changing the water, first draw out an appropriate amount of old water, and then slowly inject new water along the wall of the fish tank.
2. If the sunlight is insufficient, the breeder can install a suitable light rod on the top of the fish tank to make up for the lack of sunlight. But it is worth noting that the most suitable light for the growth of arowana is sunlight during the day, and try to irradiate the arowana with sunlight.
3. Ensure that the feed fed to the arowana is fresh and delicious. Active feed is most beneficial to the growth and development of arowana. Therefore, it is best to use some active foods such as earthworms, loach, small fish and shrimp, and cockroaches to feed the arowana, and feed the arowana to 7 points of fullness each time. If you accidentally feed too much, you must remove the leftover feed in time to avoid contaminating the water quality.
4. Keep the water quality in good condition. In addition to regular water changes, breeders need to regularly clean the aquarium sanitation to maintain good water quality. It is recommended to install a suitable filtration system in the aquarium or to regularly clean and disinfect the aquarium.
5. Regular quantitative feeding. For young arowanas, you can use some small mealworms and blood worms for feeding; for grown up arowanas, you can feed them some meat, shrimp and other foods. Of course, it is also necessary to maintain the diversification of arowana feed.
This is the end of our introduction this time. Finally, we would like to remind the breeders: when the dragon fish is found to behave abnormally or become ill, it must be treated in time. , Do not take it lightly, so as not to aggravate the condition of the dragon fish and cause more serious consequences.
