1. What is the size of the tank for raising 20 zebrafish It is best to use a tank with a length of 60 cm, a width of 40 cm and a height of 40 cm for raising 20 zebrafish. Zebrafish are not big in size, their body length is about 3-4 cm in adulthood, and they have no strong territorial awareness, and their requirements for space are not very high, so it is ok to prepare a bigger or smaller fish tank. As long as the breeding density is not particularly high, they generally do not have much problem.
2. How to raise zebrafish properly1. Water temperature: Zebrafish is a small tropical fish, and breeders need to prepare a heating rod for them. It is best to keep the water temperature between 20-23 ℃, which can ensure that they live more comfortably. They have the ability to resist cold, and they can survive as long as the water temperature is kept above 15 ℃.
2. Water quality: Zebrafish don't have high requirements for water quality, but they like clean and refreshing water. Breeders should change water once every 5-7 days, and the amount of water changed each time should be controlled at one third of the total amount of water. It is best to expose the water used by zebrafish to the sun for 2-3 days, which can eliminate chlorine in the water and slow down the discomfort of zebrafish.
3. Feeding: Zebrafish is an omnivorous fish. Breeders can choose to feed some abundant shrimp, water fleas, water lice, water earthworms, paramecium and other foods, or regularly feed some pellets to ensure their sufficient oxygen. They don't eat much, so breeders need to feed them once a day, and the amount of each feed can be eaten within 5 minutes.
