The essential guide to family fish culture knowledge, now basically every family can raise fish. With the development of economy and society and the improvement of people's material and cultural living standards, planting flowers and raising fish has become people's fashion. Let's take a look at the necessary guide and related materials of family fish farming knowledge.
Essential guide to family fish culture knowledge 1 1, filtration system.
Because the density of family fish farming is generally high, it is difficult to remove impurities and wastes from water simply by decomposing water itself. Establishing a good filtration system can effectively maintain water quality.
A good filtration system can integrate chemical, biological and physical filtration methods.
Chemical filtration relies on special drugs to condense tiny suspended impurities in water, so as to precipitate them or physically filter them out.
Bio-filtration is to use beneficial biological flora to decompose waste in water and decompose harmful substances into harmless substances.
Physical filtration is to adsorb and filter out impurity particles through the tiny pores of the filter material.
According to the characteristics of goldfish and family fish farming conditions, the following methods can be used to establish a filtration system.
According to the size of the aquarium, an external filter is configured, which can be overhead or a filter bucket.
The flow of water can be found in the description of the pump. Generally speaking, it is advisable to circulate water about 7 times per hour. For example, the volume of an aquarium with a length of 80, a width of 40 and a height of 40 is 1.28 liters, and the flow rate of the filter pump is 900 liters/hour.
For larger aquariums, in order to prevent the water from flowing too fast, it is suggested to install a built-in filter at the entrance and an elbow at the exit to reduce the impact of the water on goldfish.
Biochemical sponge and activated carbon are put in the filter box (barrel) and replaced according to the degree of water pollution.
But too frequent replacement is not suitable for the establishment of beneficial biological flora. Generally 1 month can be replaced once.
2. Biodecomposition.
In the natural environment, a large number of beneficial bacteria are attached to the places where rivers flow, which can decompose metabolites and foreign pollutants produced by aquatic organisms. Keep water clean and harmless.
Establishing beneficial flora in the aquarium can keep the water quality for a long time without changing water frequently. Adding nitrifying bacteria to the aquarium is a shortcut to establish a biological decomposition system.
Nitrifying bacteria sold in the market are mainly divided into two categories, active nitrifying bacteria and artificial nitrifying bacteria. Active nitrifying bacteria take living flora as the main substance.
Artificial nitrifying bacteria are substances that promote the growth of nitrifying bacteria in water.
Active nitrifying bacteria take effect for a short time, and generally the effect is most obvious when the water temperature is 25-30 degrees within 2-5 days. But the storage time is short, usually less than 12 months.
Artificial nitrifying bacteria have a long storage time, usually about 2 years, because they do not contain active strains, but they take effect for a long time.
Before the establishment of biological system, water quality clarifiers can be used in combination.
3. Fish culture density.
No matter how big the aquarium is, the number of goldfish raised is limited. Goldfish are lively and active, and can eat and pull.
Reasonable breeding density is very important for beginners.
Usually 1 year-old goldfish will take up 10 liter of water. That is, an aquarium with a length of 80, a width of 40 and a height of 40 has a volume of 128 liters and can support 1 fish 12. No matter how high the density is, it is difficult to maintain water quality for a long time.
In addition, different goldfish species have different requirements for breeding density, and rare species such as pearls, butterfly tails and blisters have smaller breeding density.
4. Feed selection.
Goldfish feed also has a lot to do with maintaining water quality.
Goldfish are omnivores with a wide range of food. Mainly includes: Daphnia, nematodes, hemoglobin, pellet feed, powder feed, sheet feed, etc.
Live Daphnia is the best choice. Not only in feeding, Daphnia can suck the organic suspended matter in water, but also the metabolites produced by goldfish are not easy to disperse. Nematodes, red blood worms and powdered feed may be attached to the sand bed or suspended in water, which is not conducive to the cleaning of water quality. High-quality synthetic feed will contain yeast, which can quickly decompose the metabolites of goldfish and help maintain water quality.
Inferior synthetic feed not only has no nutrition, but also contains artificial pigments, which will discolor water.
In addition, it is best not to use edible fish feed, such as crucian carp feed for goldfish, which will also spoil the water quality.
When feeding, the filter system should be closed to avoid being sucked into the filter box, which will not only cause waste, but also mold and produce toxic substances in the filter box.
5. Fish culture environment.
Lighting, scenery, etc. It is also related to maintaining the water quality of the aquarium.
Excessive light will cause a large number of algae to grow in the water. Proper curtain covering and regular cleaning will effectively control it.
Proper placement of sand bed at the bottom of aquarium will also be beneficial to water cleaning. It can not only adsorb impurities, but also provide a hotbed for nitrobacteria.
Generally, the thickness is about 4 cm, the particles are about 4 mm, and the sand layer is too thin to be adsorbed. Too thick sand bed will make the bottom sand bed lack oxygen and cause biological corruption.
Too large particles make the feed sink into the gap, which is not conducive to goldfish eating. Too small is not conducive to the oxygen transfer between water flow and particles, and is also not conducive to the growth of nitrifying bacteria.

First of all, the glass jar should be placed in a ventilated, sunny place near the window. Attention should be paid to stocking density and reasonable arrangement should be made according to the size of containers. It is better to raise more than less. Because the indoor air circulation is not good, raising more water is easy to be turbid, which can easily lead to goldfish dying of lack of oxygen. If you have a pump, you can raise more. If the goldfish is found to have a floating head, it is necessary to turn on the air pump for oxygenation, especially at night.
Secondly, for the dried fish worms sold in the market, we should choose fresh and loose particles to feed the fish, and don't buy old and moldy dried fish worms to feed them. It is best to use full-price feed with complete nutrients for artificial pellet feed, which is sold in the market.
Finally, in order to keep the water pure, the feeding amount should be strictly timed and quantified, usually 1 2 times a day, and each feeding amount should be eaten within half an hour. Don't feed too much bait. Feeding too much has two disadvantages: first, the fish is full, the metabolic level is improved, and the oxygen consumption is increased, which is easy to cause goldfish to die of hypoxia and suffocation; Second, the bait is left, which is easy to rot and ferment, making the water quality worse and causing hypoxia. In fact, goldfish are hungry, and there will be no problem if they are not fed for a week or two.
It is worth noting that it is very important to keep the water quality pure by raising fish. Latex tube should be used regularly to suck off the accumulated slag, dry the feces, residual bait and turbid water at the bottom of the glass jar, and then slowly replenish the fresh water left for one day. If the water plants float or the rockery is knocked down during the operation.
It is necessary to restore the original state in time. The longer the fish is raised, the more sediment will be deposited. Although it is removed every day, it cannot be completely removed. If the sediment increases and affects the clarity of the glass jar, it is necessary to completely change the water to clean the glass jar, so as to keep the water pure, easy to watch and maintain a good living environment for fish.
Generally, rectangular glass cabinets are used. Because of their small size, it is not advisable to leave more, and 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, six to eight goldfish with a length of 5 cm to 7 cm can be raised. Adult fish with a body length of more than 8 cm should not be kept in small glass tanks, but in luxurious large glass tanks or ceramic tanks.
And equipped with a small oxygenator for standby to prevent hypoxia. The above stocking density is for reference only, but also depends on water temperature, fish size and water quality. This cannot be done mechanically. Generally speaking, if the fish is big, it is necessary to raise less; You can raise more in winter and less in summer; You can raise more when the water temperature is low, and raise less when the water temperature is high.
Essential guide to family fish culture knowledge 3 family fish tank fish culture skills
1, fish water should be put for 3-4 days before it can be poured into the fish tank.
You can't put the newly bought fish in your own fish tank immediately after you buy it. Let the new fish adapt to the temperature of the city, and then put them in the fish tank. When you put new fish in a fish tank, you should put some crude salt to sterilize it (the big one, not the edible salt).
Don't feed the fish within 24 hours after you just bought it. When you buy fish, you should carefully check whether the fish you buy is injured. If the fish you buy dies, you should take out the dead small fish in time and put some germicide or some coarse salt.
The most important thing is to take care of the tropical fish you just bought, and don't put it in the aquarium of the existing fish immediately. Both the fish and the fish container should be put into the fish tank for about half an hour, so that the water temperature of the former is the same as that of the latter, and then the fish should be put into the fish tank. Generally, the water temperature of the fish tank should be kept at about 25℃.
5. The density of fish in the fish tank should not be too high. If there is a layer of gray sediment on the surface of the water in the fish tank, it is necessary to change the water. Tap water and boiled water cannot be directly injected into the fish tank, so they should be mixed and cooled, or they should be mixed after 3-4 days, and then injected into the fish tank when the temperature is close to the water temperature of the fish tank.
Feng shui taboo of raising fish at home
1. What kind of people are suitable for fish farming?
Fish can't live without water, so people who are suitable for raising fish must be people who like water. People born in summer are prosperous and lack of water, which is most suitable for fish farming, especially those who are irritable and impetuous. There is also a figure who takes God as water and can also raise fish. How do you know if you treat God like water?
You can find this rule through your own summary of luck. For example, you are often lucky in the second half of the year, but bad luck in the first half of the year, especially in summer, often means water music.
On the other hand, if you were born in winter, or you don't like water, you are not suitable for raising fish.
2. What kind of house is suitable for raising fish?
Houses with bright and dry indoor light are suitable for fish farming. Fish farming is to achieve the purpose of viewing and add a little vitality to home life. As far as the meaning of home feng shui is concerned, the water for fish farming is mainly used to stimulate the gas field, and the focus is not on fish, but on water. Bright light means that the house is full of light.
The indoor gas field tends to be hot, but the water for fish farming is cold, so it is easy to achieve a balance between cold and hot, so that the indoor gas field will be neutralized, people living in it will be more comfortable, have a good rest physically and mentally, and their natural luck will become prosperous.
In the same way, if you are dry indoors, it is a sign of unbalanced gas field. The water of fish farming is wet, which can be volatilized into the air, so that the dry gas field can be wetted, reaching a neutral state and forming a good feng shui gas field. The balance of indoor gas field will make people's lives healthy physically and mentally, their families harmonious and their careers smooth.
3, the choice of fish tank
For the material of fish tank, glass is the main material in the market, so there is not much room for choice. The main concern is the shape of the fish tank. Generally, it is best to choose squares and circles, squares are mainly rectangles, and circles are mainly circles, not ellipses. Other shapes, if they are small.
You can choose something different, just a little embellishment, which won't have much impact. If it is a big fish tank, don't choose a grotesque one. As for the larger fish tank, the bracket similar to the lower cabinet should be mainly dark or neutral, not too bright and not red.
