In other aspects, raising Koi in aquarium is very similar to raising goldfish. Basically, koi is fed twice a day. In different seasons of each year, depending on the temperature, the feed fed to koi is generally fed with fish worms, pellet feed, small earthworm and other feeds.
Introduction to Koi
Koi is a kind of colorful carp. It is named for its bright colors and colorful designs. Koi is a variety of red carp. In Ming Dynasty, raising red carp as ornamental fish was very popular. After the introduction of red carp into Japan, the Japanese found that the carp would change color in the breeding process. According to the characteristics of red carp easy to change, after selection, it was artificially improved into Fei carp, and many new varieties were bred, first called 'color carp', 'flower carp', later called 'Koi'. Koi has been cultivated for 200 years, and can be divided into 13 major strains, with more than 100 species. What are the characteristics of Koi different from other fish?
1. Koi is a large fish with high ornamental value. Many families choose to raise Koi to decorate their home environment.
2. The body shape of koi is similar to that of common carp, which is between common carp and grass carp. Its body is flat and spindles, with gorgeous colors and varied stripes on its surface. Its body is divided into three parts: head, trunk and tail. There are mouth at the front of the head, two pairs of muzzles at the corners of the mouth, eyes at both sides of the middle, places above the eyes, and gills at the back and bottom of the eyes. From the trunk to the vocal part, the pectoral fin, dorsal fin, ventral fin, gluteal fin and caudal fin are successively growing. The fish body is covered with scales, and each side of the body has a lateral line from the back edge of the gill cover to the vocal handle.
3. In addition to the color and mottling, the external shape and scales of different varieties of Koi are also different.
How to conserve Koi?
1. The requirements for water temperature and quality are not strict. The suitable temperature range is 2 ℃ ~ 30 ℃, and the optimum temperature is 20 ℃ ~ 25 ℃, but it can not resist the sudden change of water temperature. If the temperature difference suddenly exceeds 2 ℃ ~ 3 ℃, Koi will have discomfort.
2. Enough oxygen is needed in the water to feed carp, so carp can survive better. Moreover, koi is suitable for living in the water environment with low alkalinity and hardness, so pay attention to the water quality when raising Koi.
3. If the koi is raised in aquarium, the koi with body length below 20cm is generally selected for feeding. If the space is too large, it is easy to affect the normal activities of Koi. Moreover, it is not suitable to plant water grass in aquarium like the general ornamental fish, because the carp will eat the grass, and they have the habit of digging and eating, and they will often make all the grass out of the bottom sand, so it is not suitable to plant water grass in aquarium to feed the carp in aquarium.
4. Koi is a kind of omnivorous fish. It can be fed with synthetic particles, bait, bean cake, vegetable cake, breadcrumbs, fish worms, clams, crab meat, Wuping, duckweed, etc. in daily life. In other aspects, raising Koi in aquarium is very similar to raising goldfish. Basically, koi is fed twice a day. In different seasons of each year, depending on the temperature, the feed for Koi can be increased or decreased. Generally, the feed for Koi can be fed with fish worms, pellet feed, small earthworm and other baits. However, it should be noted that in the feeding process, do not give them too much food. Generally, 80% of the feed is enough, too much capacity It is easy to pollute the water quality and cause various diseases; moreover, if you throw too much, the carp will eat it, and if you eat too much, it will easily lead to the death of the carp.
