What's the matter with goldfish kept at home always hiding in the corner?
Second, the skills of keeping goldfish at home:
1, fish tank preparation
The choice of fish tank Family fish tanks have various shapes and more circles, which can be decided according to my hobbies and family conditions. When choosing, you should choose your favorite shape, which is in line with the home environment. Cylinder wall should be clear, bright, smooth and free from defects. Generally, put the fish in 3-4 days before buying, put pebbles and other bottom stones in it, and then fill it with clear water for later use. In this way, on the one hand, the water can be cured, on the other hand, algae can be planted on the pond wall, which is beneficial to the growth of goldfish.
(2) Pay attention to the placement of fish tanks. It is generally required to be placed in a ventilated and transparent place. Avoid direct sunlight in summer and keep warm in winter. At home, it is best to put it in a conspicuous position for easy viewing.
2. Put the goldfish in it.
(1) Goldfish are generally shipped in plastic bags filled with water, and they should be filled with oxygen when they are far away from home. After long-distance transportation, it can be packed in cartons, requiring goldfish not to be fed on the first day, and aquatic plants not to be put during transportation, so as to prevent the water from rotting and deteriorating.
(2) When the goldfish is put into the shipping goldfish, it should not be put into the fish tank immediately, but should be treated by "slow seedling" to keep the water temperature basically the same. The method is to put the plastic bag containing fish, water and fish into the fish tank for about 20 minutes, and then slowly pour out the goldfish to make it enter the fish tank. Under normal circumstances, a fish tank with a diameter of about 30cm can hold 2-3 goldfish with a body length of 3cm, which can be reduced to 1-2 in hot summer. If you are older, you can also put it down as appropriate.
Step 3 feed goldfish
① Water quality regulation
The fish tank is the whole living place of goldfish and cannot be polluted. In water, goldfish inhale oxygen dissolved in water and expel carbon dioxide. When breeding, harmful substances in the water should not be allowed to invade the fish to avoid getting sick. Therefore, the water source of goldfish bowl must have high dissolved oxygen, proper pH and no pollutants. Under normal circumstances, the water source of family goldfish breeding mainly comes from river water, pond water, well water and tap water. Natural water sources such as river water and pond water can be directly added to fish tanks as long as they are clean, non-toxic and pollution-free. Groundwater, such as well water and spring water, has large temperature difference, little dissolved oxygen and may contain minerals, so it should be sunned more and adjusted naturally. Tap water contains a lot of chlorine, which is easy to hurt fish gills and affect breathing. It should be dechlorinated, which can be placed in the open air for 2-3 days or dechlorinated with sodium thiosulfate. The easiest way to keep goldfish at home is to pump tap water into a container such as a water tank for a period of time, and then use it as the water source in the fish tank. When changing the water in the fish tank, you should also use the water from the same source. Changing a small amount of water can prevent the fish from being uncomfortable. In general, once every 3-7 days in winter and spring, once every 2-3 days in summer and autumn, and once a day when the water temperature is above 28 degrees. If conditions permit, you can often use oxygen-increasing equipment.
② Feeding with bait
Goldfish is an omnivorous fish, and there are many kinds of bait, mainly red worms, water worms, small fish and shrimp, egg yolk, tofu, noodles, rice grains, bread and so on. Goldfish raised at home can prepare their own bait or buy commercial bait. No matter what kind of bait it is, we should pay attention to the following points: first, to make the bait palatable, we can feed granular or strip bait without feeding powdery substances, and adjust it according to the size of the fish; The second is to feed regularly, when the weather is cool in summer and autumn, in the evening, and at noon in winter and spring; Third, feed goldfish quantitatively. Goldfish are prone to gluttony and can be 80% full every time they are fed. It is better that there is no residual bait in the fish tank, or we can adopt the principle of feeding several times. When the weather is hot and the water temperature is high, the feeding amount can be reduced or not. Fourth, it is necessary to diversify the bait, not to feed only one bait for a long time, but to mix the animal and plant bait reasonably to prevent nutritional deficiency.
③ Prevention and treatment of fish diseases.
Attention should be paid to disease prevention when goldfish are raised in family fish tanks. Specific measures, in addition to removing residual bait and changing water frequently, bathe the fish with 2-3% salt solution for 5- 10 minutes irregularly to disinfect the fish. If the body surface is injured, ointment such as Jintong and Fusong can be applied to the fish. In winter and spring, you should always move the fish tank to the leeward outside to bask in the sun; Put the fish tank in a ventilated and dry place in summer; Feed fresh substances, such as small fish, shrimp and snail meat. Wash with water before feeding; Adding furazolidone and oxytetracycline powder to self-made bait can prevent goldfish diseases. If anchovies and other parasitic diseases are found in fish, 2 mg of crystal trichlorfon can be put into every 10 liter of water for treatment.
