How to raise crucian carp

The shape of golden crucian carp is similar to that of common crucian carp. The main features are narrow, streamlined body, small eyes, single caudal fin, fast swimming but not afraid of people. So how to raise crucian carp?

1. Feeding

They are all fed nutritious animal feed and white sesame seeds. Animal feed such as water flea, earthworm, yellow powder worm, green worm, dermatode and so on. Earthworms and white sesame seeds are mainly fed. Both red and black earthworms can be fed. Don't feed the inferior goldfish feed you bought. Because this kind of feed has too much starch, poor nutrition, not easy to digest, water quality is easy to be polluted, goldfish eat malnutrition, goldfish growth is relatively slow, but also easy to get sick. Goldfish will not die as long as they eat food that is easy to digest. When to feed, usually once in the morning and once in the afternoon, it is not appropriate to feed more, in order to eat up. Otherwise it will pollute the water quality.

Second, lighting

It is best to put the fish tank in a place where the sun shines for 1-2 hours. In this way, the ultraviolet rays of sunlight are used to sterilize. Play the role of disease prevention. This can reduce disease. Try to give priority to the prevention of fish diseases, supplemented by medicine. At the same time, due to photosynthesis, the color of the fish is also more bright and beautiful.

Third, change water

Change the water frequently, which can increase the dissolved oxygen in the water. When changing water, you can only change 1/3 to 1/4, not a lot at once, and the fish can't get used to it. It is important to keep the water quality in the aquarium clear. Only fish with enough dissolved oxygen in the water can grow and grow fast. Otherwise, it will stop growing or even die. When to change water, there is no final conclusion, can be determined according to the water quality, the water quality is turbid more, otherwise less.

IV. Density

Home-raised rectangular aquarium because of its small size, do not raise more, less should not be more. For example, in a container with a length of 40 cm, a width of 25 cm and a height of 30 cm, 6 and 8 small goldfish with a length of 5 cm and 7 cm can be raised. For example, a round glass tank with a diameter of 26 cm and a height of 13 cm can raise 4 cm and 6 small goldfish. Adult fish with a body length of more than 8 cm should not be raised in a small glass tank, but in a large glass tank or in a ceramic tank, and equipped with a small aerator to prevent hypoxia. These stocking densities are only reference figures, and they also depend on the water temperature, the strength of the fish and the quality of the water quality. Generally speaking, fish have a large body and a small number of fish; raise more in winter and less in summer; raise more when the water temperature is low, and raise less when the water temperature is high.

Crucian carp is relatively easier to raise than goldfish, and its appearance is also good-looking, so it is very suitable for family viewing and park breeding.
