How do zebrafish divide male and female zebrafish? what is the life span of zebrafish?

Zebrafish is one of the best ornamental fish in tropical fish, and it is also the most cold-resistant fish in tropical fish, and its vitality is also extremely tenacious, so some people will begin to wonder how long this kind of zebrafish usually lives. in fact, this will also be affected by many factors. Let's take a look at it with the editor.

How does zebrafish divide male and female?

1. It is easy to distinguish between body shape and other features. Male zebrafish is slender and has large fins. Compared with the color, the female zebrafish is bright brown with prominent stripes. The female zebrafish is enlarged in size and yellowish in color, especially during pregnancy.

2. Of course, zebrafish reproduction is the best example after determining how to divide zebrafish into male and female, and knowing which is the male and female of zebrafish. The best way to reproduce zebrafish is the ratio of female fish to male fish = 1: 1 to ensure that the female zebrafish is pregnant and spawn. Female zebrafish may eat their own eggs, so make sure there are adequate safety measures before breeding.

What is the life span of zebrafish?

1. The life span of zebrafish is about 3 years. In the usual process of raising zebrafish, zebrafish will also have a lot of small problems, which will greatly reduce the life span of zebrafish. Zebrafish belongs to low temperature and low oxygen type, although the water temperature and water quality will not be too high, once there is a problem, it is easy to cause fatal injury.

2. A certain control system is needed in feeding. Feeding or other reasons will have a certain impact on the lifespan of zebrafish. Feeding as far as possible to ensure the diversity of food, zebrafish like to forage in the upper waters, basically not picky about bait, a variety of fish and insects or artificial feed is a good choice.

Is zebrafish easy to raise?

1. Zebrafish have a good ability to adapt, and many people will try to feed zebrafish with tap water. The life span of zebrafish is not very long, if we can raise zebrafish for a long time, we need to make more efforts on the way of raising zebrafish. Although the requirement of water quality and water temperature is not too good, it is easy to raise zebrafish with a certain degree of control.

2. Zebrafish, on the other hand, is highly interactive. If you use your fingers to turn around in a special aquarium, zebrafish will keep turning with the water circle, which is very dynamic. If you choose to fish zebrafish in the water, it takes a lot of effort. If zebrafish swim in groups, the ornamental effect is better. However, a maximum of 5 zebrafish per liter of water is the best, there is a certain amount of room for movement, if you have a good water cycle environment, then there are not too many factors to consider.

3. In feeding, zebrafish eat thin slices of feed, and small fish and insects are the favorite of zebrafish. During feeding, zebrafish will take the initiative to eat, if many different species of tropical fish are mixed, it is very difficult for other species to eat food. Zebrafish breeding is not a big problem as long as it is given a good water environment.

How to raise zebrafish so as not to die?

1. In view of the fact that the zebrafish is not very large, if long-distance transportation is added, symptoms such as maladaptation and fish disease are easy to occur. Before the zebrafish enters the prepared special aquarium, the process of mixing water must be done to ensure that the zebrafish can adapt to the surrounding environment. On the first day, the zebrafish can not be fed in a hurry, give it a quiet environment to rest, and when the situation improves the next day, there is an impulse to find food, and you can open it with a small amount of live food. And then slowly restore the amount of food.

2. Although zebrafish is small, the energy brought by food also plays an important role. First of all, zebrafish food demand is different, harvest shrimp, paramecium, granular feed, egg yolk water, etc., according to different stages of zebrafish growth to provide different food sources. Zebrafish has a very advantage, zebrafish has a good ability to recover, in order to ensure that the water temperature is normal, there is basically no big problem.

In fact, zebrafish have a wide range of food, it can be said to eat everything, as long as they can swallow, but in our usual feeding, we can still choose more nutritious food, mainly red nematode, frozen red worm or tropical fish feed, good feeding, zebrafish life may also be longer.
