Zebrafish is a common tropical fish. Zebrafish is gentle and small. It can swim in aquarium almost all day long. It is easy to raise and can be mixed with other kinds of fish. The feeding water temperature is 20-23 ℃, and it can survive at 11-15 ℃.

Introduction to zebrafish
Zebrafish is a common tropical fish. Zebrafish is gentle and small. It can swim in aquarium almost all day long. It is easy to raise and can be mixed with other kinds of fish. The feeding water temperature is 20-23 ℃, and it can survive at 11-15 ℃.
Zebrafish are slender and reach sexual maturity about 3 months after hatching. Mature fish can lay eggs every few days. In vitro fertilization, in vitro development, embryo development synchronous and fast, embryo body transparent. The development temperature should be between 25-31 ℃. Zebrafish can be bred on a large scale because of its small size and low cost.
Because the similarity between zebrafish gene and human gene is 87%, which means that the results of drug experiments on zebrafish can also be applied to human body in most cases, so it has attracted the attention of biologists.
Fish embryo mutants are excellent resources to study the molecular mechanism of embryonic development. Some of them can also be used as human disease models. Zebrafish has become one of the most important biological models of vertebrate development, and its utilization in other disciplines also shows great potential.
How about zebrafish?
Zebrafish body color is silver or gold, covered with some blue or purple stripes. These stripes extend from the head to the back of the tail fin, and there are also stripes on the hip fin and tail fin. The back is light olive yellow. The male is longer than the female, but smaller. The body length can reach 3.8 cm. There are many cultivated varieties.
Seattle, University of Washington, has been studying zebrafish to try to solve the problem of hearing loss in humans. Like many other aquatic organisms, zebrafish have hair cells on its surface. The function of these hair cells is to detect the vibration in water, and its principle is similar to that of hair cells in human inner ear. However, unlike humans, zebrafish hair cells can regenerate after being damaged. The researchers hope their work will uncover the mystery, protect human hair cells from damage and promote the regeneration of hair cells.
Introduction of zebrafish species
Blue zebra, red zebra, yellow zebra, spray point zebra, electric light zebra, lightning zebra, leopard zebra, rainbow zebra, red and gold zebra, Galaxy zebra, blue zebra, tiger zebra, etc.
Zebrafish is a new model animal for the study of developmental biology. Zebrafish has become a new model animal for the study of vertebrate development and human genetic diseases due to its advantages of easy feeding, transparent embryo, in vitro fertilization, multiple mutant species and mature genetic tools.
