CATDOLL : CATDOLL: The most fertile ornamental fish Three most fertile fish

The most fertile fish in the world The most fertile fish in the world

1. Guppies are ovoviviparous fish with strong reproductive capacity and early sexual maturity. Although the life span of guppies is only one or two years, they grow very fast with adequate nutrition. They will become sexually mature after one month and can reproduce after 3-4 months. Generally speaking, a female guppy has a reproductive cycle of 23-28 days, and some are even faster. The first birth is about 10-20, and the number gradually increases. Some guppies can produce more than 100 at a time. The biggest feature of guppies is that they give birth frequently and have a high survival rate. Moreover, guppies are ovoviviparous fish. Even in the absence of male fish, female fish can keep sperm in their bodies for a month.

2. Black Mollies are ovoviviparous fish, and the fry can reproduce after 5 to 6 months of growth. Black Mollies have a strong reproductive capacity. Under the condition of sufficient bait and good water quality, female fish can reproduce once every 30 days. The first litter is 10 to 50, and the number gradually increases, and the maximum number can reach more than 200.

3. Red swordfish is also an ovoviviparous fish. It has strong reproductive capacity and early sexual maturity. The young fish are sexually mature at 3-4 months and can reproduce at 6-7 months. Of course, the time of sexual maturity is also related to the water temperature and breeding conditions. Female red swordfish can give birth once every 4-6 weeks, which is affected by the size and age of the female fish and the ratio of the male fish to the breeding fish. Each time, 30-300 fry can be produced.

Which ornamental fish breeds quickly and is easy to raise?

1. Angelfish

It is a bit difficult to keep angelfish in captivity at first because of their large size and aggressive nature. Angelfish can grow to about 15.2 cm in captivity and you will need to keep them in more than 30 gallons of warm water, but if you do, they are very easy to grow.

2. Fighting Fish

Breeding bettas is a good choice. Breeding bettas does not require filtered water or any special environment. You just need to remember to change the water once a week. However, bettas are very aggressive and cannot be placed with other fish, especially male bettas.

3. Black Skirt Fish

This fish is quite mature and beautiful in appearance. It swims freely in the water. It likes to gather in the middle of the water, so it is easy to watch. The black skirt fish is not picky and eats everything, and eats a lot. Sometimes the black skirt fish likes to hide in the corners of the rocks.

4. Andreas spheniscus

This fish has a long lifespan, some can live up to 10 years. They are highly adaptable and can survive in temperatures between 60 and 80 degrees Celsius.

These are some of the longest-lived fish. If you live up to 10 years, you can guess how resilient they are. Andromeda spp. move in large groups, sometimes 5 or 6 at a time. They are small and can survive in a small aquarium.

5. Goldfish

Goldfish is a typical ornamental fish. Many people raised goldfish at home when they were young. They are easy to raise. Just put them in clean water and feed them occasionally. However, goldfish can only be raised with goldfish. Although goldfish are good, many people's goldfish died after a few days. In fact, whether it is freshwater fish or ornamental fish, breeding requires certain skills. Many people like to consult experts for free on Yunzhongyang when they have any breeding problems. Yunzhongyang is the largest agricultural technology question and answer website, which brings together tens of thousands of agricultural experts. The questions raised will be answered by experts within two minutes, which is a great help to fish farmers.

6. Guppy

Guppies are very cute, they breed a lot, and they swim in pairs. If you keep 16 liters of water, 3 pairs are enough, and more will be too cramped.

7. Snake fish

Snake fish does not like to be watched. It often swims at the bottom of the fish tank, where it can often pick up some food to eat. Just like the black skirt fish, it hides in places that people cannot easily see.

8. Crescent Fish

These fish are popular because they are not picky eaters and will eat anything they are fed. They will also clean up the algae at the bottom of the tank. They come in many colors and are very beautiful to watch. In a warm tank, they grow and reproduce very quickly.

9. Swordtail

The swordtail fish gets its name from its shape, its tail is like a sword, and they are not aggressive and can be kept with other types of fish.

10. Golden Fish

If you look up at the clouds in the sky, you will think of this fish because they can live in low-temperature water. Like the guppy, this fish likes to live in groups.

Notes on fish farming:

Feeding: Feed in moderation and stop when the baby is 80% full.

The most common mistake that many novices make is to feed their beloved fish constantly, feeding them based on personal preference. In fact, you don’t know how the fish’s excrement and leftover bait affect and damage the water quality. So I suggest that you feed the fish once a day in a newly opened tank, and it is best to finish eating within 3 to 5 minutes. Feed less on rainy days and do not feed at night. Fish need to consume more oxygen in the process of digesting food. On rainy days and at night, the air pressure is lower, and the dissolved oxygen in the water is also low. Feeding fish at this time may cause severe hypoxia in the water and cause fish death. Most fish deaths occur at night, and severe hypoxia in the water is one of the main reasons. So, just make sure that every fish eats the bait.

2. Water change: Change water regularly and keep the amount of water moderate.

Everyone knows that raising fish in a fish tank is different from raising fish in a natural environment. We need to change the water regularly to maintain the ecological balance of the entire fish tank. So avoid changing the water too often or not changing the water for too long and changing too much water each time. When to change and how much to change depends on what kind of fish you feed and how many fish you feed. I usually change a quarter of the water once a week and slowly add it back to the tank over 40-60 minutes. In this way, the water quality and pH of the new water will not have much impact on the fish. If all the water is changed and the water quality suddenly changes, they will not be able to adapt, their physical fitness will decline and they will get sick. If you need to rinse the bottom of the tank, you should also keep most of the old water. After washing the tank, return the remaining water to the tank and then add new water.

3. Filtration: The filter material is stable and should not be cleaned for a long time.

No matter what form of filtration you use, the nitrifying bacteria that have been established on the filter material will be lost due to your diligent cleaning. Without them, your fish will lose the greatest guarantee! Therefore, replacement and cleaning should be carried out one-third each time (it is recommended to only wash the front filter cotton) to ensure the health of the fish. If the water quality is poor after cleaning, you must stop feeding for 2-3 days.

4. Temperature: neither too high nor too low, just the right temperature.

As soon as you hear "tropical fish", you know that they need to be heated. Some fish need higher temperatures, some need lower temperatures, but generally between 24-29 degrees, which is basically acceptable. Some friends put the heater horizontally, and I have encountered that it keeps heating or does not work at all when it is placed horizontally, so it is better for everyone to follow the instructions.

5. Fish: Do not raise fish of different water quality together.

It is a common problem for beginners to buy whatever they like. They don't know the water quality and habits of the fish at all. After buying it home, the fish bite each other. They don't know that tropical fish with different attributes cannot coexist. Carnivorous fish bully and eat herbivorous tropical fish. They can get other diseases or even die. Fierce fish and gentle fish cannot be raised together; fish with too many individual differences cannot be raised together (gentle fish species can be considered); fish with different water quality requirements cannot be raised together, etc. Now it is generally divided into 3 categories: acidic, neutral, and alkaline. When buying fish, you must understand whether it is suitable for mixed breeding with the fish at home.

6. Fish tank: In fact, the smaller the fish tank, the higher the difficulty.

To keep fish well, the waste concentration in the tank must be controlled within a small range. However, I think the smaller the tank, the harder it is to control the waste concentration. Try not to use built-in filters because all the waste is in the tank. So I suggest that novices try to have upper filtration, which can discharge a lot of ammonia, nitrite, etc.

7. Put into the tank: add water for disinfection, don't be careless.

When we buy fish, the JS will usually tell us to "put the bag in the fish tank first, and wait until the temperature is the same before putting the fish in the tank." In fact, this is not enough, and it also needs to be diluted with water and disinfected. Soak the plastic bag containing the fish in the fish tank for ten to twenty minutes before opening it, put the fish in a basin, put one thousandth of potassium permanganate, and use a water pipe to draw the water in the tank into the basin 3-4 times, with an interval of 5-10 minutes each time. This will not have a big impact on your newly bought fish. Let the water in the tank flow back into the bag several times, and gradually mix with the original water in the bag, so that the fish can gradually adapt to the water temperature and water quality. Of course, it depends on the fish, peacocks, maps, etc., to ensure the water quality, and the temperature difference should not exceed two degrees. If there is light, turn off the light. In the dark, the fish are quieter and less likely to be frightened.

8. The bait must be clean.

This is the easiest thing for beginners to overlook. Feeding unclean bait can easily lead to fish diseases. It is recommended to buy branded frozen fresh food produced by professional companies, such as bloodworms, brine shrimp, etc. Although live worms such as water earthworms and water red worms are the favorite of tropical fish, live worms grow in polluted water environments and are very easy to die and rot during temporary breeding. Therefore, it is necessary to be cautious when feeding live food. It is also necessary to pay attention to the impurities and leftover bait at the bottom of the tank that are not cleaned up in time or the filtration effect is poor, which will cause the water quality to deteriorate.

9. Keep the water clean.

After eating, tropical fish consume a lot of oxygen and excrete a lot of waste, which pollutes the water and breeds bacteria. In order to keep the water clean, a high-efficiency filter must be installed. If you raise fish in a bare tank, you must replace one-tenth or slightly more of the old water while removing the precipitate from the bottom of the tank every day, especially in summer. It must not be neglected. For an ecological tank where fish and aquatic plants are raised together, it is sufficient to replace 1/3 to 1/4 of the water once a week.

10. Landscaping: Different landscaping requires different equipment.

I mentioned above that it is recommended for beginners to use top filtration, but it is not absolute. If you have a planted tank, you cannot have top filtration. You need a CO2 system and a filter tank. If you have three lakes, you'd better use trickle filtration, which will help you remove highly toxic ammonia. Planted tanks need acidic ADA mud or silica sand, and three lakes tanks need

Use alkaline coral sand or Philippine sand.

11. Pay attention to the density of fish stocking.

Pay attention to the density of fish. Tropical fish like a large space to move around. Beginners often buy the fish they like, rarely considering how many fish they can keep in the tank.

This point requires special attention. Usually, one liter of water should be used to raise a 1 cm long fish. If your fish tank holds 100 liters of water, it is safe to feed at most 10 tropical fish of 10 cm in length. I personally insist on keeping about 1.5 liters as the control target. In a larger space, fish are more active, strong, and colorful. Raising too many, too dense, lack of oxygen in the water, and deterioration of water quality are the main causes of tropical fish illness and death.

12. Problem: Don’t panic and handle things calmly. If you are not careful, gentle and steady during the operation, you may suddenly turn on or off the light, knock on the tank wall, and cause the tropical fish to panic or even hit the tank.

13. The three most common mistakes that newbies make are:

(1) Prescribing drugs indiscriminately. Prescribing drugs indiscriminately for even the smallest problem.

(2) Random water changes. If the drug does not work, the water is changed drastically, causing the pH to fluctuate severely.

(3) Cleaning the filter carelessly. Finally, you may wonder if there is a virus in the filter, so you clean it thoroughly. However, you don’t realize that after the first three steps, you have pushed your fish to a point where it is difficult for them to survive!

Guppies are viviparous, so the survival rate of their young is high. If well raised, they can reproduce many times within a year. The young fish can reproduce again when they are a few months old. They will reproduce so many that you have no place to keep them. Hence, they are nicknamed "million fish".

There is basically no need for heating in winter: Koi and Chinese carp are easy to raise and can be fed with anything. Chinese carp can give birth to hundreds of small fish in a nest and they can make their own nests.

Tropical fish: The only equipment required is a heating rod costing 20 yuan, and a little electricity bill. Fish that are easy to raise and can reproduce, such as the Mary fish, red arrow, and peacock, all give birth to baby fish and the fish will grow up on their own without any care. However, there should be more grass in the tank, and when there are baby fish, just feed them some powdered food.

You can go to the store to see which one you like, they are all very cheap.
