Koi Fish
Koi fish is a kind of giant guinea fish. It is generally better to breed it in a huge fish tank, so that koi fish can have legs. There is enough space for movement. Currently, most koi fish are mainly grown artificially. Therefore, owners should pay attention to several aspects when raising koi fish at home.
1. Selection and arrangement of aquariums
Aquarium tanks of different specifications should be selected according to family conditions. However, due to the living habits of koi and goldfish, However, this kind of animal has a large body and a strong amount of exercise, so the aquarium should not be too small, and the general water capacity is preferably no less than 60 kilograms. To raise larger-sized koi, the aquarium should be enlarged appropriately, and the water capacity should be no less than 200 kilograms. Because koi have a large amount of exercise and consume a lot of oxygen, the aquarium must be equipped with a water filter and an oxygen pump to ensure sufficient oxygen in the water and clean water quality.
2. Bait and feeding methods
Koi is an omnivorous fish, and you can choose dry food regardless of animal or plant food. Koi bait, such as water fleas, water earthworms, rice and pasta, etc. However, it is better to use synthetic bait that is specially used for guinea fish. When feeding in the aquarium, special attention should be paid to not overdoing the feeding amount. According to the normal observation situation, only feed 70 to 80% of the volume, otherwise it will cause adverse effects, ranging from indigestion to fish leftover food. Damage to water quality, it is best not to feed at dusk.
3. Water quality and temperature
The feeding conditions of koi are different from those of goldfish. It requires higher water quality conditions, with a neutral pH (PH7 -7.4) is appropriate. Turbid and whitish water in the aquarium is most likely to produce dead fish. If this happens, measures should be taken immediately or the entire water should be replaced. The most suitable water temperature is generally maintained between 15-25℃.
4. Not suitable for mixed culture
Koi is a kind of omnivorous giant gorilla fish, and the living habits of various ginseng fishes are different. , so it is best not to mix it with other species of fish. When raising koi, since everyone's preferences are different, the raising conditions are also different. Therefore, the selection of koi should be based on the individual's preferences, the level of raising, and family conditions. The following points should be paid attention to when choosing:
1. Choose a koi with regular body shape. Because koi is common with other fish, some extraordinary phenomena will occur in genetics. Some young fish are gifted with abnormal traits, such as head tilt.Slanted, distorted body, etc., this kind of fish is not worth considering and should be removed first.
2. Pay attention to whether the fish has obvious trauma, bleeding and other symptoms. Although some fish have no obvious external injuries or diseases, they swim slowly and sluggishly, have a loss of appetite, often float on the water or get stuck in the corners of the aquarium, which indicates that the fish's internal organs are suffering from other symptoms and should not be used for treatment. About the elephant.
3. It is to choose fish with distinct species characteristics, that is, to choose individuals with pure color and body patterns that can produce certain artistic patterns.
4. It is decoration that focuses on color and variety. < p > When entering the fish tank or fish pond, since the water temperature will vary, you need to immerse the koi fish and the bag in the water and let it sit for about 30 minutes. When the water temperature inside and outside the bag reaches a normal level, pour the koi fish and the water into the empty basin. Otherwise, if the water temperature varies by 2-3°C, koi fish will catch colds and get sick. Also, if the koi fish you just bought are to be mixed with the previous fish, it is best to keep them in 5% salt water for a few days, conduct separate inspections, and carry out insecticide and sterilization procedures if necessary. , to prevent the new fish from carrying diseases, insect pests and bacteria and infecting the already healthy fish.
Koi fish and goldfish generally do not have very strict requirements for water temperature and water quality. The suitable temperature range of koi fish is 2℃ ~ 30℃. However, one thing that needs to be noted is that koi fish cannot withstand water temperature. Sudden changes, for example, if the temperature difference of the water suddenly exceeds 2℃~3℃, koi fish will feel uncomfortable. The optimal water temperature for raising koi fish is 20℃~25℃, which requires sufficient oxygen and is suitable for living in slightly alkaline and hard environments. In low water quality conditions.
Koi fish do not have high environmental requirements, but koi fish cannot adapt to changes in water temperature that alternate between hot and cold. During the breeding process, the water temperature of the aquarium must be controlled to maintain water quality. Cleanliness, these are very important.
