If you raise orchid goldfish in a deep tank for a long time, it will affect their body development. Because Lanshou goldfish belong to egg goldfish, their bodies are round after maturity. Although they can survive in deep water, the water is too deep, which will affect their growth. If they are raised in deep water for a long time, their bodies cannot develop beautifully. Therefore, breeders usually raise Lanshou, and the water level can be controlled between 30-40 cm. If the breeding density is low, or the Lanshou goldfish is small, the breeder can also keep the water level at 20-30 cm.

Lanshou goldfish is not large in size, and its requirements for oxygen and water quality are not very high, so it is a kind of fish that is easy to raise. However, the specific size of the cylinder depends on the number of rearing and the size of the body. Generally speaking, a 60 cm long fish tank can raise about 3 adult Lanshou. You can also raise 6-7 pieces about 10 cm. Or raise 10-20 pieces below 5 cm. In addition, besides the size of the fish, it depends on the equipment in the fish tank. If the breeder has installed filters and oxygen pumps, the breeding density can be higher. If these devices are not installed, the feeding density will be reduced.
