How to feed ornamental fish must first learn to buy good fish: healthy fish swim in the middle and lower water (except the upper water) and compete for food. The swimming posture is natural and leisurely, the tail fin is clear and elegant, the eyes are clear, and the individual is large. Sinking to the bottom, floating head, swimming and struggling, trauma, white hair and white spots, thick caudal fin, turbidity, severe bloodshot, dark body color, turbid eyes, being single and alone, refusing to eat or wiping the jar with your body are all sick fish, so you must not buy them.
If you plan to mix several different kinds of fish in a fish tank, you must pay attention to the compatibility between different kinds of fish. Fierce fish and docile fish can't be kept. There are too many individual differences to be mixed (temperate species can be considered); Different water quality requirements cannot be mixed, and so on.
When buying, energetic large and medium-sized fish should not only be inflated to keep oxygen, but also covered with black bags to reduce external interference to the fish. High-grade fish should be bagged separately to avoid injury caused by mutual contact. Pay attention to heat preservation when buying fish in winter. Plastic bags for fish must be thick and reliable, especially those with hard fins.
A fish tank can't change too much water at a time, which will lead to water quality discomfort. Water quality includes pH value, hardness, chloride ion, dissolved oxygen, nitrate, sulfide, protein and turbidity.
Pay attention to the density of fish. Overfeeding, high density, lack of oxygen in water and deterioration of water quality are the main causes of fish illness and death.
How to feed. The most important thing to see a fish tank is to control feeding, and it is advisable to eat once or twice every 3 to 5 minutes. Feed less in rainy days and not at night. Fish need to consume more oxygen when digesting food. The air pressure is low in rainy days and at night, and the dissolved oxygen in the water is also low. In this case, feeding the fish may lead to serious hypoxia in the water and kill the fish. Most dead fish occur at night, and severe hypoxia in water is one of the main reasons.
The bait must be clean, which is the easiest thing for beginners to ignore. Feeding unclean bait can easily lead to fish diseases. It is recommended to buy brand frozen fresh foods produced by professional companies, such as red worms and bumper shrimp. Although live worms such as earthworms and mealworms are the favorite of fish, they all grow in polluted water environment and are easy to die and rot in temporary culture. So be careful when feeding live food.
Keep the water clean. Fish will consume a lot of oxygen, discharge a lot of waste, pollute water and breed germs after eating. In order to keep the water clean, a high-efficiency filter must be installed. If the fish are raised in a bare water tank, it is necessary to remove the educts from the bottom of the water tank and replace one tenth or a little more old water every day, especially in summer. The ecological tanks for fish and aquatic plants only need to change the water of 1/3 ~ 1/4 once a week. The filter adopts aeration design, so that filtration and aeration can be carried out simultaneously, which not only purifies water, but also supplements oxygen. However, the water tank cannot be inflated.
Don't bring grease and detergent into the water. Oil pollution will float on the water surface to isolate the air, so that the oxygen in the water can not be replenished, leading to the death of fish due to lack of oxygen. Eating meat and even applying hand cream will bring oil into the water, so be careful to avoid it. Accordingly, fish tanks should be far away from places where oil and natural gas are produced.
It's best to start with low-priced and easy-to-raise fish and accumulate experience before raising rare species, so as to be handy and successful.
Key points of raising ornamental fish: Newly arrived marine fish may eventually settle down in China, just like tropical freshwater fish. Marine fish are fish that live in the ocean. Therefore, it is necessary to have relevant equipment and take relevant measures to simulate the living environment in the ocean. The temperature should be controlled at about 25℃, and the salinity should be between 1.020%- 1.023%, and animals and plants in the sea should be placed. Such as coral, anemones, sea crabs and seaweed. Only in this way, marine fish are willing to live and work happily here and continue to live.
Ornamental fish, composed of goldfish and tropical freshwater fish, is divided into two parts, and now it has become a three-part world because of the addition of tropical marine fish. Marine fish, a big family from the ocean, began to appear in the markets of flowers, birds, fish and insects all over the world and are swimming into people's fish tanks.
It is difficult to raise marine fish, but it is easier said than done. As long as you master the essentials, it is better than goldfish tropical fish, and you need to change the water once a year, and change 1/3 every time. The key lies in the control of water quality and salinity. Otherwise, the fish will die in as little as three to five days and as much as two weeks. Of course, if you raise it well, you can live for three or five years. Marine fish are mainly related to corals, anemones and seaweeds. Therefore, putting corals, anemones, seaweed and other things in the fish tank can not only intersect with marine fish, decorate their living environment, but also provide food and clothing for marine fish! Of course, in artificial breeding, some nutrient solution should be added on time to adjust.
Because marine fish has just been listed, it is quite rare in the market, and it has just begun to appear in the markets of flowers, birds, fish and insects around the country, with about 20 varieties.
They have different shapes and personalities. There is a small and exquisite radar fish, no more than an inch long. It looks like a leaffish in a pond, but it shines like a firefly, which makes people realize its difference. Its value is about 5000 yuan. There is also a black and white zebra fish, which is particularly enchanting in the crystal clear water and playfully shuttles between seaweed. Its value is also high, and it costs several hundred yuan each. Maybe it's because things are rare. Almost all marine fish on the market cost hundreds of thousands of dollars. If a whole tank is used, it will definitely cost tens of thousands. So, almost all of them are rich but not expensive? Generous? The young man's? Patents? .
Feeding skills of ornamental fish After the fish is put into the feeding container, the most basic work every day is feeding. The feed of ornamental fish is mainly granular feed, which has the advantages of comprehensive nutrition, appropriate feeding amount and unfavorable deterioration of water quality. The particle size varies with the species of ornamental fish. Ornamental fish raised at home are usually fed once a day, and the feeding amount is about 70% to 80% full. Feeding time can be chosen at the time of day that you think is the most free. Just pay attention to the rules and don't feed at will. Be careful not to feed at night, otherwise it will easily cause indigestion. If you forget to feed the fish for something, you can feed it normally at the next meal. Generally speaking, it will not be a big problem for fish to be hungry for a few days.
