What fish can be raised together with zebrafish? Zebrafish breeding method

Danio rerio is a freshwater fish belonging to the Cyprinidae family. It is native to South Asia and is a popular aquarium fish. Danio rerio is very lively and will swim back and forth in the fish tank, chasing and playing. Fish that are timid and prefer a quiet environment are not suitable for being raised with Danio rerio. So what fish can be raised with Danio rerio? Let's take a look!

What fish can be kept together with zebrafish?

Zebrafish can be raised together with small non-aggressive fish, such as peacock, moonlight, Mary, etc.

It should be noted that small non-aggressive fish are usually quiet. Although they can be raised together with zebra fish, it looks inharmonious. Other fish that can be raised together and are relatively harmonious include red and green lantern fish, black lotus lantern fish, white cloud gold silk fish, penguin fish and other lantern fish.

The zebrafish has an elongated and slightly spindle-shaped body, a small and slightly pointed head, a short snout, and is covered with many dark blue vertical stripes like a zebra, alternating with silvery white or golden vertical stripes in a relatively orderly manner. When they swim in groups in an aquarium, they are like a group of zebras galloping on the African grasslands, hence the name zebrafish.

Zebrafish breeding method

1. The preparation of the research tank for the breeding method is mainly cleaning and disinfection. The boiling water disinfection method is used. The disinfection is thorough and there are no problems left after chemical disinfection. It is also the most environmentally friendly method.

It is important to place the jar flat when disinfecting, it must be flat, otherwise it will crack easily. Then add a small amount of boiling water to let the glass adapt to the temperature to prevent the glass from bursting due to sudden high heat. Finally, add an appropriate amount of boiling water for disinfection.

To cultivate water, let tap water stand for 3 to 5 days to evaporate the chlorine in the water. Then add the water to the disinfected tank, add nitrifying bacteria, and use water fairy to continuously oxygenate for 24 hours to initially establish a nitrification system. This water can then be used to stock fish.

2. Receive the fish. After receiving the fish, do not rush to open the box. Open the box in a dark place after returning home. Avoid vibration or rolling caused by excessive movement during the journey.

Because the fish have stopped eating, are in a dark environment, and have been transported over long distances for a long time, they are physically weak and mentally stressed, so you need to be especially careful to prevent the fish from getting scared and hitting the bag or tank, or from clamping their tails due to fear. Therefore, all work must be done gently and carefully.

3. Add water (also called water transfer, a professional term). Adding water is an important and tedious operation. But if you want to raise fish well, you must be careful and patient to complete it, to ensure that the fish can initially adapt to our breeding environment smoothly and lay a good foundation for normal breeding in the future.

Why is the zebrafish's belly bulging?

If the zebrafish has a bulging belly, it is likely that it is about to reproduce. Check if it is the breeding season. During the breeding season, the belly of the female zebrafish will become very large. If not, it is likely to be an intestinal disease, such as parasites. In this case, the sick fish should be isolated as soon as possible to avoid infecting other healthy fish. In addition, medication should be used in time. Be careful when feeding and managing in the later stage, especially water quality issues.
