One, 100 liters of water raise several orchid longevity 100 liters of water can be loaded in an 80*40*40 cm fish tank, according to the size of the fish tank. A fish tank with a length of 80 cm can raise 3-5 adult Dalanshou, 10 10-20 cm, or 20 5-10 cm. However, the growth and development speed of Lanshou goldfish is relatively fast, so breeders should change the fish tank or reduce the feeding density according to their growth speed. In addition, the specific number of breeding should be determined according to the equipment of the fish tank. If the filtration system is perfect, the number of breeding can be more, and if the filtration system is poor, the number of breeding can be relatively reduced.
2. How to raise Lanshou goldfish1. Water temperature: Lanshou goldfish, like ordinary goldfish, has low requirements for water temperature and strong adaptability. In the normal feeding process, they can develop well only by keeping the water temperature between 20-26 ℃.
2. Water quality: Lanshou goldfish likes weakly alkaline old water, and breeders can change the water every 3 days. It is most appropriate to control the amount of water change at one third of the total water amount each time. When changing water, pay attention to the temperature difference between new water and old water to avoid their discomfort in production.
3. Feeding: Lanshou goldfish have a wide range of food habits and can eat more kinds of food. Breeders can feed more animal feed in their infancy, which can be fed 3-4 times a day, and each time they are fed 6-70% full, so as to ensure their adequate nutrition. As an adult, you can feed more synthetic feed, which only needs to be fed 1-2 times a day, and each time you are fed to 70% full, so as to ensure balanced nutrition.
