several Manlongyu. The number of Manlongyu is closely related to the size of the fish tank. Because Manlongyu has a strong sense of territory and offensive power, the density of Manlongyu can not be too large. Generally speaking, a 40-centimeter fish tank can raise 10 Manlongyu, because the size of Manlongyu raised artificially is not very large, and it is about 10-15 centimeters after adulthood. Although Arowana can be raised in groups, it is better to mix with other fish if conditions permit, because they are prone to fight in groups, and the sense of competition among the same kind is strong, which can be reduced by mixing with other fish.
Manlongyu 1. Water temperature: Manlongyu is a tropical fish. Its favorite water temperature is between 22 and 28 degrees Celsius. In winter, it is necessary to install a heating rod in the fish tank for constant temperature. The lowest temperature of Manlong fish should not be lower than 18 C, otherwise they will have decreased resistance or poor development.
2. Water quality: Manlongyu does not have high requirements for water quality, as long as it is kept fresh. If you don't have a filter pump, you can change the water twice a week. If you have a filter pump, you can change the water once a week. Tap water can be used to raise Manlongyu, but it needs to be exposed to the sun for 2-3 days before it can be used after all the chlorine in the water volatilizes.
3. Feeding: Manlongyu has miscellaneous feeding habits and can eat more food. Generally, breeders feed some special dried fish food for Manlongyu, as well as some harvest shrimps, red worms, nematodes, etc. Adult Arowana can be fed 1-2 times a day, the amount of each feeding does not need to be too much, and it is best to eat within 5 minutes.
