To raise Lanshou goldfish, the flow rate of water pump can be adjusted to be smaller. Specifically, the flow rate of water pump is equal to 8-10 times of water capacity. Because they are small in size, and in goldfish varieties, they belong to a kind of clumsy action. If the water flow is too large, it will affect their rest. In addition, if the water flow is too large for a long time, Lanshou goldfish will swim all the time in order to resist the water flow. When they keep moving for a long time, they are more likely to die suddenly. If the water flow is too small, it is impossible to suck away all the food residues and feces in the fish tank, so the breeder needs to control the water flow.

The best water level of Lanshou goldfish is 30-40 cm. If the raised Lanshou goldfish is small in size or quantity, the water level can be controlled between 20-30 cm. As mentioned above, they are relatively small compared with other goldfish, and their activities are not flexible, so the low water level is most suitable for them. If the water level is too deep, the amount of dissolved oxygen in the water will decrease, and breeders need to take oxygen regularly to ensure sufficient oxygen. In addition. If the water level is too deep, it will also affect their growth and development, so that their body shape cannot develop better. If the water level is too shallow, there will be less room for them to move, so it is best for breeders to raise them according to the best water level.
