What Are Zebrafish?
What is a zebrafish ?Most varieties of zebrafish have bright colors that are very nice to look at, and zebrafish are one of the more popular ornamental fish around the world and ideal for those just starting out with tropical fish.
What is Zebrafish
The zebrafish is a genus of fish in the carp family Cyprinidae, also known as the blue striped fish, flower striped fish, zebra striped fish. The body is fusiform. Dorsal olive color, the side of the body from the gill cover straight to the end of the tail has several silver blue longitudinal stripes, the anal fin also has a longitudinal stripes similar to the body color, the caudal fin is long and forked. Lemon colored longitudinal stripes in males, blue longitudinal stripes plus silvery gray longitudinal stripes in females. With dark blue and silver longitudinal stripes. Lifespan is generally 2-3 years, up to 5.5 years.
How to Keep Zebrafish
Zebrafish are very easy to keep tropical fish, comparable to guppy in terms of roughness of management. If you want to learn how to raise and breed oviparous fish, you should start with zebrafish. Place a female with a bulging abdomen and two males in a small, calm aquarium lined with rocks and grasses, preferably of the fine-leaved, long-stemmed variety, and keep the water at about 25 degrees Celsius, preferably old water that has been collected from the breeding tank during water changes.
The zebrafish is very adaptable to water temperature, and can survive in water temperatures from 10 to 40 degrees Celsius, but essentially they prefer lower water temperatures, and the optimal feeding water temperature is 18-25 degrees Celsius.
The best feeding water temperature is 18-25 degrees Celsius. Acidic or alkaline water has little effect on zebrafish, but they prefer soft old water. It is better to inject some rainwater or distilled water after water change, if too much raw water is added at once, it will stimulate them to jump out of the water. Zebrafish like small live bait, and can also eat commercial feed and green food. In order to minimize the rise of dirt caused by their constant disturbance of the water, the bottom of the aquarium should be paved with sand and some stones to retain the dirt. Installing effective filtration equipment in the aquarium will make them healthier.
Scientific Value of Zebrafish (Water Mice)
Zebrafish have about 30,000 genes in their genome, about the same number as humans, and many of the genes have one-to-one correspondence with humans. The central nervous system, internal organs, blood and visual system of zebrafish are 85% identical to humans at the molecular level. In particular, the early development of its cardiovascular system is very similar to that of human beings, therefore, zebrafish is the best experimental animal for the study of cardiovascular disease genes. Tumorigenesis in zebrafish is also very similar to that of humans. The genetic characteristics of zebrafish make it a good model for human tumors.
