CATDOLL : CATDOLL: Which tropical fish is easy to raise?

Question 1: Which ornamental tropical fish is the easiest to raise? Hello:

Guppies, moonfish, red arrowfish, zebrafish, red light fish, gourami, mollies, and tiger barbs are all easy to raise.

Things to note when raising tropical fish:

After the newly bought fish get used to the new environment, you can start feeding them. Generally, after the fish are placed in the base water tank for half a day, if you find that the fish start to peck at the wall or sand on the bottom of the tank, it means that you can start feeding them. Some fish refuse to eat when they change their environment, so you need to feed them the feed they like. You can feed them a balanced amount of artificial feed and daily feed. Pay attention to the amount to avoid leftovers, because the leftovers will rot and damage the water quality.

Several reasons that cause tropical fish to become sick and die:

1. The water temperature changes dramatically. The best temperature for tropical fish to survive is 25℃, but different species have different temperature requirements, some require as high as 30℃, and some prefer 20℃. Therefore, on average, 25℃ is a generally acceptable temperature.

2. Too high stocking densityDDDMany people see that aquariums can put many cute fish in one fish tank, so they also raise many fish in the fish tank at home. This kind of breeding method will kill all the fish. If you raise many different kinds of fish, you must consider the suitable living space for each fish and reduce the number of fish. No matter what kind of fish, a small tank with many fish is never a good thing.

3. Types of feed DDD The feeding habits of tropical fish vary from species to species and can be roughly divided into three categories: animal, plant, and omnivorous. Therefore, we must understand the type of fish in the tank, what kind of food they like to eat, and classify and feed them well.

4. Disease DDD There are many reasons why tropical fish get sick, including infection from purchased sick fish, white spot disease caused by too low temperature, and water quality deterioration due to leftover food corruption or decomposition of fish feces and waste.

i. The difference between a “new” aquarium and an “old” aquarium

The main difference between the two is that there are no minerals or other nutrients in a "new" aquarium for plants to absorb; however, the bottom and side walls of an "old" aquarium are rich in nutrients, such as nitrogen fertilizer, phosphorus fertilizer, etc. Therefore, in an "old" aquarium, water plants will grow rapidly at the beginning, and after a few weeks, these nutrients will turn into debris and settle. In a "new" aquarium, the number of bacteria is very small; on the contrary, the bacteria content in an "old" aquarium is quite high, and contains organic matter, leftover bait, excrement, and many non-nutrient salts. Bacteria can decompose these wastes together with dead plants into harmless substances, which are lacking in a "new" aquarium.

ii. Substances that cause death in a "brand new" aquarium

After we set up a brand new aquarium, we waited for 1-3 weeks before putting the fish in. We were originally very happy, but found that some or all of the fish died. We carefully studied the causes of their death: most of them died due to suffocation or gill swelling, and even the installation of high-performance ventilation equipment did not help. At this time, the most effective and only way is to change the water frequently, or immediately transfer the surviving fish to another "old" aquarium. This situation also often occurs in aquariums with new filters installed. What is going on? It turns out that the fish in the aquarium did not die because of insufficient dissolved oxygen in the water, but because of nitrogen compound poisoning! Because there are not enough bacteria in the brand new aquarium to convert the toxic nitrogen compounds in the water into non-toxic nitrates.

iii. Nitrification:

There are trillions of bacteria living in "old" aquariums. Different bacteria have different jobs and tasks. They will decompose or convert organic nutrients into water, carbon dioxide and various inorganic salts through many processes of oxidation. Proteins will be broken down into amino acids and converted into inorganic salts of ammonia. Fish will excrete ammonia and urine, and enzymes in the water will break them down into ammonium salts and carbon dioxide. Some nitrifying bacteria can use oxygen dissolved in water to convert ammonia into nitrites, which are then decomposed into non-toxic nitrates. This whole process - ammonia → nitrite → nitrate → is called "nitrification".

iiii. Characteristics of nitrifying bacteria:

Most bacteria need about 20 minutes to reproduce by cell division, while nitrifying bacteria that oxidize ammonia need 2-3 hours to divide, and some even need 20-30 hours. Therefore, when other types of bacteria are multiplying in large numbers, the reproduction rate of nitrifying bacteria will lag behind significantly, resulting in the non-nitrogen organic matter in the water being decomposed quickly, while nitrogen compounds and ammonia are decomposed slowly. This is also the reason why most aquarium enthusiasts believe that nitrogen compounds in water are the most difficult to decompose......>>

Question 2: Which tropical fish is the easiest to raise? 1. Newbies usually start with peacock tail and red swordfish. These fish have a variety of diets and do not require high water quality. More importantly, they are viviparous and directly reproduce small fish, which is particularly suitable for beginners to learn! There are many varieties of peacock fish. The colorful peacock, black peacock, white peacock, etc. are the easiest tropical fish to raise. They are not strict about water quality. The water temperature can be between 18℃ and 26℃. All baits that tropical fish can eat can be used to feed them.

The map is also OK. This kind of rain eats small fish. It looks beautiful and grows fast.

Let's take a look at some of the ones copied from other places.

Kissing fish. Easy to raise and breed, the water temperature can be between 20℃ and 26℃; it can be fed with bloodworms, nematodes, glutinous rice worms, dried worms, plant feeds and artificial feeds. This fish will kiss each other (actually fighting) after 3 months, so be careful when raising them in mixed tanks.

Black Marlin. Water temperature 24℃ to 27℃, weak alkaline hard water, adding a small amount of salt is conducive to raising black marlin. Black marlin likes to eat plants; they can also eat animal baits such as fish worms and nematodes.

Zebrafish. It is named after the zebras running on the African savannah. The water temperature for raising it is generally 23℃-25℃. It is the easiest tropical fish to raise. It does not require special care and is less susceptible to diseases and insect pests.

Red swordtail fish. It has strong adaptability and can live in water temperatures between 20℃ and 25℃. It can live in weakly acidic, neutral and weakly alkaline water. Swordtail fish are omnivorous fish and can eat any bait that tropical fish can eat.

Red Tetra. Easy to keep, but difficult to breed. The water temperature should be controlled between 22℃ and 25℃. It can be kept in weakly acidic, neutral and weakly alkaline water. The feed should be mainly bloodworms and nematodes.

2. First, choose the big head, and pay attention to whether there is a bulge at the junction of the fish head and the dorsal fin. It is very small, so look carefully.

Then look at the mouth. A big head should be matched with a short mouth. The short mouth mainly depends on the lower lip of the fish. The front end of the lower lip is in an "L" shape. This is what we usually call an overbite. Because the upper lip of the fish is short, the lower lip must be folded upwards so that the fish can eat. If you pay attention to the fish with a pointed mouth, the lower lip is flat.

Look at the body shape again, and pay attention to the distance between the fish's dorsal and anal fins and the caudal fin. The closer they are to the future, the shorter the body shape will be.

The beads and sequins are natural and will be visible at 5 cm. For color, choose the ones that are colored early and bright.

But why is it so hard to find such small fish in the market? Because the fishmongers have already picked out the best ones. On the other hand, there are too few of the best ones. But the above knowledge is enough for you to pick out the best ones from a group of fish.

Question 3: Which freshwater ornamental fish is the best to keep and is not a tropical fish? The Chinese fighting fish. Although it is classified as a tropical fish, it is produced in the subtropics, so it is very resistant to low temperatures and does not need to be heated in winter.

Question 4: Among tropical fish, which fish is the easiest to raise? Peacock tail and red swordfish. These two fish have a variety of diets and do not require high water quality. More importantly, these fish give birth to live young fish directly, which is especially suitable for beginners to learn!

There are also golden mandarins, cichlids, glass fish, and tiger fish, which are all tropical fish with strong adaptability.

Golden pineapple, blood parrot, and map too.

Question 5: Which tropical fish are easier to raise? Five types of fish suitable for beginners: red light fish (0.5), zebra fish 0.5, guppy 2 yuan (male and female are easy to distinguish, you can buy two types, hehe, you can give birth to baby fish), red sun 1, temperature control is required, it is best to have a small filter, raising fish is very happy

Question 6: What tropical fish are suitable for family breeding? I run an aquarium. Peacock fish are not easy to breed. I recommend novice breeders to breed tiger fish, colorful skirt fish (small fish) or map fish, parrot fish (large fish). However, no matter what fish you breed, the configuration of the fish tank is the most important. To breed fish well, it is best not to use a too small fish tank. You should choose a larger fish tank, configure a good filtration system, and maintain good water quality. There are many other precautions, which I will not introduce one by one here.

Question 7: Which type of fish is more suitable to keep at home? Which type of fish is easier to keep? Hello:

Goldfish are easier to raise.

Tropical fish:

Traffic lights, guppies, moonlight fish, red swordfish, kissing fish, tiger barbs, and zebrafish are all easy to raise and suitable for beginners. In addition, guppies are the easiest to raise. They are not only beautiful in color, but also low in price and requirements. They also reproduce quickly, with a reproduction number of about 15 to 80. I wish you success in fish farming! ^_^

Question 8: Which tropical fish are easy to raise? Generally speaking, medium-sized parrots and map fish are recommended. For small fish, ovoviviparous guppies and red swordfish are recommended as entry-level species.

These fish are resistant to low temperatures, have no strict requirements on water quality, have strong adaptability, have a diverse diet, and are not expensive.

Simply put, it is durable and cheap

Question 9: What kind of ornamental fish is good to raise at home? Fish that must be easy to raise 1. You can raise cold water fish. Koi, crucian carp, goldfish, etc. are all fine. No heating rod is needed. Most cold water fish require a higher amount of dissolved oxygen, so the oxygen must be sufficient and pay attention to the fish density.

2. Raise larger tropical fish in a bare tank.

It is colorful, has a great visual effect, and is not difficult to raise.

Parrots are easy to raise and look good, especially blood parrots, but they can eat and defecate, so you need to pay attention to maintaining the water quality.

The sharp-nosed crocodile can be raised by those who like fierce fish. It is very fierce and relatively easy to raise.

Three rooms, three crown rooms and three emperor rooms. They do not require high water quality and are easy to raise.

It brings wealth, you can’t raise too many of them, they will fight with each other of the same kind, but it is easy to raise.

Others include dinosaurs, anti-swimming cats, red-tailed cats, seven-star knives, spotted tigers, warships, etc.

2. Raise larger tropical fish in a grass tank.

The one-browed Taoist priest is domineering among the group and is absolutely shocking.

3. Mixed breeding of small tropical fish.

Common small tropical fish on the market include: peacock, Mary, moonlight, arrow tail, rat fish, Lili, pearl vest, Dutch Phoenix, African Phoenix, tiger skin, red cross, zebra, traffic light, lotus lantern, red nose scissors, black lotus lantern, glass cat, reverse swimming cat, kissing mouth, small angelfish, etc.

If you want to experience the fun of raising small fish, you can raise fish such as: Peacock, Mary, Moonlight, Arrowtail, etc.

If you like more beautiful and quiet fish, you can raise short-necked fish, such as: Lili, Pearl Vest, various types of Phoenix, Jinbozi, etc.

If you want to lay bottom sand and grow grass, you can raise tetras, such as: red and green tetras, lotus tetras, black lotus tetras, emperor tetras, red-nosed scissors, zebra tetras, etc.

If you like more active fish, you can raise tiger skin, red cross, etc.

The fish used as tools are: kissing mouth, Mary, various cory, scavenger, black line flying fox, shrimp, snail, etc.

Question 10: Which tropical fish is the best to raise? Anchovies are relatively easy to raise. They are not very demanding on water quality and temperature, and have strong adaptability. They can survive in water temperatures above 18 degrees. I have raised them before, and they don’t need to be heated throughout the winter. They just don’t like to swim very much. But when changing the water, you must pay attention to the consistency of the temperature of the new water and the old water. This fish is small in size and gentle in temperament. It is best not to raise it together with other species of fish.

Food: Red nematodes, water fleas and dry feed are all acceptable.

Disease prevention: When changing water, pay attention to maintaining a certain ratio of new water and old water. Unless there is a special deterioration in water quality, all water can be replaced. But when changing all water, pay attention to controlling the temperature difference between new and old water to not exceed 5℃, so as not to get sick.

Treatment method 1: Increase the water temperature appropriately.

2 You can use 12.5 ppm chlortetracycline or 25 ppm oxytetracycline aqueous solution to soak for 30 minutes; you can also use 1 ppm bleaching powder or 2 to 4 ppm (2 to 4 ppm) gallnut to spray in the aquarium for disinfection.

Female anchovies are large and plump, while male anchovies are small and thin.

After the fish grow up, they can lay eggs once a month in summer. When the belly of the female fish bulges, it means that she is about to give birth. Generally, the female fish will give birth after about 20 days of pregnancy. You can put the female fish alone in a small tank, because the female fish may swallow her own children. After laying the fish, you should raise the small fish separately. Anchovies do not recognize their relatives and often breed with their relatives. You can ignore it, but it will affect the quality and quantity of the next generation of fish.
