First of all, you have to confirm whether you have positive or negative aquatic plants. As the name implies, positive aquatic plants like more sunshine, so they should have plenty of sunshine. Negative aquatic plants can appropriately reduce the lighting time, but they should also be illuminated. After all, plants need photosynthesis. In the choice of lamps, try to choose fluorescent lamps. Because the spectrum of fluorescent lamp is close to that of sunlight, it is beneficial to the growth of aquatic plants.
Secondly, positive aquatic plants should use CO2 cylinders, which can be found online. The role of CO2 is beneficial to the growth of aquatic plants (absorbing CO2 during the day and releasing oxygen). The opposite is true at night).
Question 2: How to cultivate aquatic plants in tropical fish tanks The necessary equipment for raising tropical fish is:
(1) Fish tank: It is the place where tropical fish grow and move. Tropical fish must be raised in a slightly larger rectangular glass fish tank.
(2) Suction tube: it is used to suck out the dirt at the bottom of the fish tank when changing water, and is formed by connecting a soft rubber tube and a glass tube. The length depends on the height of the fish tank. Generally take one meter two to one meter five.
(3) Thermometer: used to measure and adjust the water temperature of the fish tank.
(4) Fishing nets: used to catch and transfer tropical fish.
(5) Glass lamp tube: put the bulb into the glass lamp tube and sink it into the fish tank for heating and lighting. The glass lamp barrel mouth must be higher than the water surface 100MM to prevent fish from jumping in.
(6) Electric heating tube: used to raise the temperature in the fish tank in winter.
(7) Air pump: discharge the carbon dioxide in the fish tank and increase the oxygen content in the water.
(8) Filter: filter out the dirt in the fish tank, keep the water clean, and play a dual role in increasing oxygen and purifying the water.
(9) Thermostat: It is used to automatically control the temperature in the fish tank and can keep a constant temperature for a long time.
(10) Feed hopper: prevent fish food from floating on the water surface, which is beneficial to fish predation. It can also prevent fish food from falling into the bottom of the water and drilling into aquatic plants, blackening aquatic plants and sand and destroying water quality.
(1 1) Decontamination liquid: made of plastic plate. Used to scrape the dust and oil on the water surface of fish tank.
Peacock fish is the first choice for newly cultivated tropical fish.
Peacock fish is a small tropical ornamental fish, generally 3 to 5 cm long, petite, agile and lively, and colorful. It is mainly produced in Brazil, Venezuela, Guyana and the West Indies in South America. According to their different characteristics, it can be divided into common guppies, phoenix-tailed guppies, long-tailed guppies, guppies and yellow guppies.
It should be said that among many tropical ornamental fish species, guppy is not a noble fish species, and its price and requirements for the surrounding living environment are not high, but it is deeply loved by people because of its liveliness and beauty. Especially the male fish is more beautiful. Its green-brown body is mixed with red, orange, yellow, green, blue and purple, just like a rainbow in the sky, so it also has a nice name-rainbow fish. At the same time, because its abdomen has several small blue spots, and there are light-colored wheel rings around the spots, which are very similar to the eye spots on a proud peacock, so it is also called peacock fish.
Some fish buyers told reporters that peacock fish is popular largely because it is gentle and lively, will not fight with other fish, and is suitable for mixed culture with some non-aggressive fish; Moreover, the selectivity to food is not great, and egg yolk, steamed bread residue and so on can be fed, but it is best to feed live bait such as fish worms and nematodes when raising artificially; At the same time, the requirements for water quality and water temperature are low, and it is very easy to raise and survive.
Generally, purebred guppies are large in size, with large and stretched caudal fins and dorsal fins, pure in color, distinctive in characteristics and high in price, because the quality of their strains varies from about 10 yuan to about 50 yuan; On the other hand, hybrids or degenerated species are cheaper, and they can be bought for only a few dollars per pair. But for people who have just raised tropical fish, it is more economical to buy hybrid degenerated species, because they can accumulate a lot of experience in fish farming.
In addition, it's best to make sure whether you buy fish for viewing or breeding. If you just want to watch, you can choose individuals with bright colors, long tail fins and normal development of each fin; If it is a well-bred guppy, it is best to choose a young and energetic guppy, because fully mature guppy is not suitable for breeding, although their tail fins are large and the patterns are gorgeous.
Generally speaking, the principle of choosing guppies is not much different from that of choosing other fish, except that there is no abnormality on the body surface, no wound, no damage to the fins, no contraction of each fin, no growth of white hair and white spots, and a desire to eat and a quick response. It is best to choose individuals who are not injured or killed in the whole tank. However, a key point in purchasing guppies is to choose males with large body, large tail fin, stretching and lively swimming. Usually buy two or three months old guppies.
In addition, don't forget to buy an aquarium while buying guppies. The fish tank for keeping guppies had better not be too big. Generally, it is suitable to be 60 cm long, 30 cm wide and 40 cm high, and you must pay attention to testing the water before buying to ensure no leakage.
After the peacock fish is selected, the next step is the bait problem. Peacock fish does not have high requirements for bait, and generally can use Daphnia, earthworm or compound pellet feed.
When everything is selected properly, we will reach the breeding hole ... >>
Question 3: How to raise aquatic plants in ordinary glass fish tanks? Common cultivation methods of aquatic plants
Planting aquatic plants in fish tanks is of great significance to the breeding of tropical fish. If you only raise fish in a fish tank without planting aquatic plants, its ornamental value will be reduced, which will make people feel that there is something missing in the tank and it will look desolate. If some aquatic plants are planted properly, fish will swim back and forth in the branches and leaves of aquatic plants, and the ornamental value will be greatly improved. Only in this way, planting aquatic plants is also very important for the growth and reproduction of tropical fish. Aquatic plants carry out photosynthesis during the day, releasing the oxygen needed by tropical fish and absorbing the carbon dioxide exhaled by tropical fish. Aquatic plants can also absorb and digest harmful substances such as fish feces during their growth. Some tropical fish have to lay their eggs on the leaves of aquatic plants to hatch. Aquatic plants are ideal resting places for tropical fish. They block strong light and create a comfortable living environment for tropical fish. Aquatic plants can also purify water and precipitate dirt.
Most of the aquatic plants planted in China are imported from abroad, and * * * can be divided into four categories:
1. Submerged plants: take root under water and grow stems and leaves in water.
2, emergent plants: take root in the water, grow stems in the water, and the leaves are exposed or floating on the water.
3, floating plants: leaves floating on the water, roots and stems hanging in the water.
4. Intermediate plants: don't take root in water, but reproduce and grow in water.
(1) crown grass
Crown grassland is produced in Brazil in South America. Also known as Amazon sword grass and crown grass. Crown grass is a large aquatic plant. Its petiole is stout and its leaves are broad and beautiful. The largest crown grass can grow nearly 100 leaves, the largest of which is 50 cm long and 8 cm wide. Crown grass is luxurious, gorgeous and magnificent, and is known as the king of aquatic plants.
Crown grass likes strong light, has strong adaptability and is easy to grow, and should receive about four hours of light every day. The leaves of the crown grass are brittle, so don't move often to avoid damage. The stem propagation and ramet propagation of can are mainly stem propagation. The stem of can grows towards the water surface and obliquely upward, and each rhizome can grow more than a dozen grasses, sometimes two or three rhizomes can be added at the same time, which shows its strong fecundity. When the root of Ranunculus ternatus is long enough to be planted, it should be cut off and planted separately. If the roots of Ranunculus ternatus grow new plants, when they grow to about 20 cm, they can be cut down and planted separately.
(2) Watermelon grass
Watermelon grass is also called melon net grass, melon sword grass and melon grass. The plant shape of watermelon grass is like crown grass, with short leaves and wide leaves. On its grass-green leaves, you can see clear veins, just like those of watermelon skin, so it is called watermelon grass.
Watermelon grass has strong adaptability and likes strong light, but its longevity is slow. The propagation method of watermelon grass is the same as that of crown grass.
(3) plantain grass
Banana grass is a medium-sized aquatic plant with large round leaves, uneven leaves, slightly wavy leaves and short stems. Ye Quan is in the water, which is very ornamental. Banana grass also has climbing stems, which adds to its beauty. Banana grass has strong adaptability, fast growth and strong sunlight.
The propagation of plantain grass is also carried out by ginseng stems.
(4) Water lilies
Water lily is a kind of big grass, which can be compared with crown grass. Its leaves and stems are thick and long and can grow to the surface of the water. Leaves are very wide, can grow to 20 cm long, 10 cm wide, floating on the water, and the leaves of tin lotus float on the water, so it is called water lily.
Water lilies like strong light, which lasts about 4 hours every day.
The propagation mode of water lily is ginseng stem propagation, which is the same as crown grass.
(5) Pepperweed
Pepper grass can be divided into green pepper grass and purple pepper grass The main difference is that the leaves and stems of green pepper grass are green, while the leaves and stems of purple pepper grass are lavender on the back and green on the front.
Pepper grass is called pepper grass because its leaves look like pepper leaves at first. Pepper grass has strong adaptability and is easy to grow. It should receive about four hours of light every day. The leaves and stems of pepper grass are fragile; Don't move often, lest it break down.
Pepperweed is propagated by ramets. New plants are often born in its roots and can be planted separately after its roots grow.
(6) Loquat grass
Loquat Orchard is a lush aquatic plant, which is produced in subtropical zone. Eriobotrya japonica has symmetrical leaves, stout stems and rapid growth. In order to make the plant shape of Loquat grass beautiful, it is necessary to make it grow more branches when it reaches a certain height, so that Loquat grass can grow into a crown shape, which is very beautiful.
Loquat likes strong light and should receive about four hours of light every day.
The propagation of loquat grass adopts cutting method. Cut a piece from its branch and plant it alone, and you can survive.

Question 4: How to maintain the aquatic plants in the fish tank? The growth conditions of stem aquatic plants are as follows: 1, and the light should be sufficient, otherwise the spacing between stem nodes will be widened, which will affect the appearance and growth. 2. The PH value in water is mostly weakly acidic, preferably 6.4 ~ 6.8; The hardness in water should not be too high, and should not exceed 4 dKH and 10 DGH. 3. The amount of carbon dioxide added should be enough. 4. Fertilizer The roots and leaves of stem plants will absorb nutrients, so both base fertilizer and liquid fertilizer should be sufficient. 5, the temperature should be appropriate, about 2 1~26℃, lower than 18℃ or higher than 30℃ will stop the growth of aquatic plants. Bulb aquatic plants Bulb is different from ordinary aquatic plants, it absorbs nutrients, only the roots absorb nutrients, but the leaves do not. 1, the light needs enough light, such as water lily, but some varieties can still grow under low and medium light, such as water lily and purple water lily. 2. Water quality generally requires fresh water, slightly higher hardness, and a PH value of around 7.0. Net grass should pay attention to the low nitrate in water. 3. Most grass species need to add carbon dioxide, such as nettle grass. 4. Fertilizer requires high base fertilizer, and when base fertilizer is enough, it will flourish. 5. The temperature and water temperature are higher than other aquatic plants, about 22~28℃. Pepper grass doesn't like too new water quality, because its own water purification capacity is very small (the proportion of nitrate absorbed from water). Whether there are microorganisms such as nitrifying bacteria in the water tank will also affect the cultivation of pepper grass. Lighting should be sufficient, such as small gas pickled pepper grass; But some pepper grass can still grow in weak light, such as mini pepper grass. 2. water quality the PH value of pepper grass ranges from acidic to weakly acidic. Generally, when the pH is higher than PH7.0, it is difficult to cultivate or even lead to the dissolution of leaves, and the hardness of water is low; The content of nitrate in water is low, even without nitrate. Pickled peppers like weak alkaline and high hardness water because of their native place. 3. It is necessary to add a proper amount of carbon dioxide to carbon dioxide. 4, the fertilizer pepper grass is mainly based on base fertilizer, and the amount of liquid fertilizer is small. When liquid fertilizer is added more, the density of water will increase than before, which will make pepper grass lose its balance and dehydrate and wither. 5. Temperature The planting temperature is about 22~28℃.
Question 5: How to raise aquatic plants in tropical fish tanks can decorate fish tanks, and more importantly, it can also provide places for ornamental fish to hide and lay eggs. Moreover, the organic matter produced by the decomposition of the residual bait and feces of ornamental fish can be absorbed and utilized by aquatic plants as nutrients, thus purifying the water quality.
The aquatic plants planted in tropical fish aquariums in China are mostly induced species, and their origin is mainly tropical and subtropical regions, followed by temperate regions. There are many kinds of aquatic plants, no less than potted plants on land. According to their shapes and properties, aquatic plants can be divided into the following categories:
(1) Aquatic plants rooted at the bottom of the water and with open leaves in the water;
(2) Aquatic plants with roots at the bottom and leaves floating on the water;
(3) Aquatic plants with roots at the bottom of the water, leaves coming out and flowers in the air;
④ Rootless aquatic plants floating on the water;
⑤ Aquatic plants without fixed roots, stems and leaves.
Among the above aquatic plants, the first aquatic plant is the most suitable for raising tropical fish.
Aquatic plants often planted in tropical fish aquariums are as follows:
① Pteris vittata;
Grass stems are slightly thicker and leaves grow with potato stems, so it has strong viability, fast growth, strong adaptability to temperature changes and strong endurance. Strong reproductive ability, as long as the cut stems are inserted into the sand, they can survive.
2 bamboo shavings;
Shaped like kelp, wavy and wrinkled, it is also called kelp grass and wrinkled orchid. Eupatorium adenophorum has strong adaptability, fast growth and strong illumination, and needs 4 hours of illumination every day. It has a tuber (also called perennial root) similar to sweet potato, and new plants will grow on it. If plants have fibrous roots, they can be cut off and replanted.
③ reticular grass;
Netgrass has white flowers, so it is difficult to breed in the country of origin and in the aquarium, so most of it depends on imports, which is very expensive and precious. Netgrass is very strict with light. Too strong, that is, it will grow full of moss and affect growth. Too weak, easy to die. It is a kind of water plant that is difficult to grow. The water temperature of netted grass should generally be kept at around 25℃, and it will stop developing when it exceeds 28℃. Attention should be paid to planting netted grass: laying thick sand; Keep the water clean; The water temperature should be around 25℃; It is best to plant it in the shade under large aquatic plants or dim the light.
(4) water tree in Yamala;
It looks like a woody plant, with leaves like the bottom of a boat, about 5 cm long, symmetrical left and right, and it grows on a thick horizontal stem in Kaidi Zhang, which is very strange. It belongs to cold-water aquatic plants, and the suitable water temperature for its growth is 20-25℃. Although not fond of high temperature, but fond of strong light, it can be propagated by cutting and transplanting dry stems.
5 Tian Jihuang;
This is a bryophyte. Its leaves and stems grow together, slender, tufted, dark green, and do not like strong light. It is necessary to change it frequently or take it out for cleaning frequently to grow faster. Hypericum japonicum can grow and reproduce by itself without artificial planting, which is mainly used for tropical fish reproduction.
6 chrysanthemum grass;
The stems are thick and symmetrical, the leaves are like chrysanthemum leaves, the adaptability is strong, there is no obvious requirement for the water temperature, and the reproductive ability is strong. As long as you cut off a rhizome or a leaf, you can insert it into the sand to form a new plant.
All landowners water celery;
It belongs to a kind of pteridophyte in water, with leaves similar to radish leaves, strong adaptability, fast growth and the strongest reproductive ability among aquatic plants. It can be planted in submerged water or floated on the water surface, which is very important for the reproduction of perch family. It can be propagated by dividing plants or pruning, and new plantlets can be born by itself after the leaves are aged.
8 water mushrooms;
Leaves, such as mushrooms on land, are attached to the center of specially shaped dry leaves; Strong endurance, easy reproduction, rapid growth, like low water temperature, when breeding, stem buds can grow laterally at the root.
Pet-name ruby floating daffodils;
It is a floating aquatic plant, like a blooming rose. Its leaves are thick and round, and the yellow leaves are covered with micro hairs, which has the function of drainage. It is a refuge for small fish, and can also be used to climb perch and spit to build a nest. It is one of the indispensable aquatic plants for tropical fish reproduction.
Attending the crown grass;
The petiole is stout, the leaves are wide and beautiful. The leaves of a large plant can reach 100, and the leaves are about 50 cm long and 8 cm wide. Crown grass is luxurious and magnificent, and it is called "the king of aquatic plants" in some places in China. Likes strong light and is easy to plant, but the leaves are fragile and should not be moved frequently to avoid damaging the leaves. Mainly look at the stems of ginseng.
Others include: crinkled grass, snapdragon, watermelon grass, broadleaf water lily, short-leaf water lily, big-leaf water lily, pink water lily, water lily, big-leaf water lily, moss, water lily, willow grass, plantain grass, alpine rush, saxifragon, green willow, willow, sibagon, water lily grass, Polygonum cuspidatum, Abida pepper grass and so on. & gt
Question 6: The first advantage of raising aquatic plants in fish tanks is that they look good and feel more natural.
And it's good for fish.
Question 7: How can aquatic plants grow well in a fish tank? Hello: Aquatic plants mainly rely on oxygen in the water, in other words, to raise water. Then the problem of water is that fish manure pollutes the water quality. Besides filtration, the most important thing is ecological balance. It's better to raise some small shrimps to eat the garbage on the grass. It is not easy to clean the fish tank without laying stones.
Question 8: How to raise aquatic plants and fish in the aquarium? Introduction to raising ornamental fish: all friends who have just started raising ornamental fish have this experience. Buy back the fish and put it in the fish tank. Everything was fine in the first few days. After a few days, I saw that the water was muddy and the fish had faded. I didn't know the fish was sick until I asked. "What? Will fish get sick? " With a grain of salt, I invited a doctor and gave medicine. My wallet hurts badly. I spent a lot of time, and my hair may turn white. Finally, every fish saw Lao Mao. Bite your teeth and buy more. For a few days, I got sick again, cured again, died again, bought again, and went on and on. Unconsciously fall into a strange circle. Finally, there is a feeling that fish farmers who can't cure fish are not good fish farmers. Ha ha. Think about it. Am I wrong? This is a beginner's problem. Everyone will commit a crime. Not surprising. It is strange that some people can't extricate themselves. Caught in the strange circle of Dr. Fish and couldn't get out. It is believed that raising fish is to treat fish constantly. Harmful microorganisms in the aquarium mainly refer to pathogens such as viruses and bacteria. Harmful compounds are various inorganic salts produced in water, such as phosphate and nitrite, which will do harm to fish. In addition, feed live bait to friends who admire fish (such as water lice, filariasis, blood worms, etc.). ) long-term capture from nature will inadvertently bring in some organisms and pathogens (such as fish lice, cat head lice, viruses, etc. ) is basically the main cause of diseases of ornamental fish cultured in aquariums. Compared with rivers and lakes in nature, aquariums are much smaller and more isolated. The high fluidity of water in nature makes all kinds of harmful salts there quickly washed away by the current, and a large number of elements in natural water will also neutralize some harmful salts. The wide water body in nature also makes this fish have a wide range of activities. In order to survive, they have to run around for food and avoid predators. The chances of infection and invasion by pests will be much smaller. Then, in view of these points, we can formulate methods to prevent diseases. First of all, there should be fewer big fish in the fish tank. That is to say, the density of fish farming should be relatively small, and 1cm fish should be raised per liter of water. This breeding density is the experience summed up by many predecessors. You can lower the density a little. Second, the arrangement of filters. Some friends will only buy an air pump when they start raising fish. If you think the water is short of oxygen, pump it up. If it is turbid, change it. It doesn't matter whether you buy a filter or not. This idea is very dangerous. As we said in the colorful article on captive equipment, the filtration device in the present sense refers to biochemical filtration. It is no longer simply removing impurities from water. It is a method to establish a good circulation system and improve the hydrological environment by eliminating harmful substances in water through microorganisms. This is a system that must be prepared. In my experience, the gap between filter channels should be bigger and longer. The impurities are filtered by coarse cotton filter for the first time, and then filtered by nitrifying bacteria attachment groups such as biochemical cotton filter, biochemical ball or ceramic ring, so that nitrifying bacteria attached to it can play a role. Then the harmful elements such as chlorine and cadmium are removed by activated carbon filtration. Finally, filter it with a cotton filter and put it back in the aquarium. This kind of filtration is my experience in raising fish. Because, in order to save money, I usually don't use the finished filter screen, but set up my own filtering device. This will be much cheaper. Third, the speed of water flow is higher. It depends on the kind of fish. You raise fish in warm water or even still water. You can't wash it with big water, can you This means that the circulating water flow is as large as possible on the water flow it can bear. To simulate natural water flow. Fourth, lazy people can't raise fish. Fish farmers must develop good habits and monitor and check the water quality and the living conditions of fish every day. This job is boring. But you have to do this. Carefully check the hydrological indexes such as pH value and nitrite content of water. Observe the body of the fish. Is there anything wrong with the shape and movement of the fish? Early detection of fish infection and prevention of infection. A friend who buys fish said that only those who sit in front of the fish tank for 1 or 2 hours after returning home every day and stare at the fish without blinking an eye can be counted as entering the territory. Haha, it's not that exaggerated. But you need to keep observing every day, and it is best to keep an observation diary. 5. Change some water every three to seven days. Old water is the key to raising fish well, but new water is also essential for the metabolism of fish and aquatic plants. Six, the control and disinfection of bait. This is extremely important for friends who feed natural live bait. Some time ago, many friends emailed me and asked me why I said I couldn't feed Qicai with silkworms, but he didn't use it ... >>
Question 9: What aquatic plants are best kept in the fish tank? Your local wild aquatic plants, hehe, are actually quite good as long as they are not tropical aquatic plants. Just buy it, sterilize it, put it in the jar and fix it. I don't know how your tank conditions are suitable for growing grass. Can't there be too many fish? Can I give you some forums to play with? In order to raise a water plant, I came to ask you if you want to play a career or something, and I don't want to listen to theory. Then I'll say I think Yeshuicao's answer is quite consistent with your question. Wow haha
