CATDOLL : CATDOLL: What large tropical fish are easy to raise and look good?

What large tropical fish are easy to raise and look good?

Parrots: Types/Blood Parrot, Macaw, Purple Parrot, Heart Parrot, Candy Parrot

(A good-looking macaw costs 40 yuan per 5-8 cm) + a golden pineapple + a scavenger. Don't mix too many species, it won't look good. When matching the species and density of large tropical fish, consider that the fish will grow larger.

You can also choose fish such as Golden Pineapple, Black Cloud, Red Pearl Guandao and Pearl Firemouth to match. In addition to having diverse body color combinations, they can also achieve a state of peaceful coexistence under a certain balance.

Map of the God of Wealth: A large fish that can eat and excrete. It is easy to raise and breed. Because the map fish is large, a larger aquarium must be selected when raising it. Because this fish has a large appetite and a strong excretion ability, it grows very fast and can be matched with anything. Seven-star knife fish, also known as bowback fish, seven-star flying knife fish, Oriental knife fish, flower knife fish. Distributed in India, Myanmar, and Thailand.

Silver Arowana: Silver Arowana is easier to keep than to breed. The difference between male and female broodstock can be seen mainly in the pelvic fins. The male has a longer and sharper pelvic fin, while the female has a swollen abdomen. Males need more than 5-6 years to reach sexual maturity, while females need more than 6-7 years to reach sexual maturity. They have a strong tendency to choose their own mates. Breeding requires weakly acidic soft water with a high oxygen content and a water temperature of 27-28℃.

Man-of-war fish: Man-of-war fish is native to rivers and lakes in the Greater Sunda Islands in Southeast Asia. However, since this species of fish is an extremely important edible fish species in Southeast Asia, it is widely farmed. It can be said that it is extremely easy to raise this species of fish. There is almost no difficulty. It can adapt to weakly acidic, neutral, and weakly alkaline water. However, it prefers weakly acidic to neutral water. The required temperature is 23-28 degrees.

Fierce: Fish

Red-tailed catfish: This fish is easy to keep and grows very fast. Keep them individually if the size difference is small. Sharp-billed crocodile: Also known as gar, duck-billed crocodile, gar family. Originated from the Great Lakes region of North America, it belongs to the gar family. Fish: The dorsal fin of fish changes to produce a sharp venomous stinger, which sometimes kills people when stung. The stinger is renewed every year. Fish generally live in shallow seas with a depth of about 100 meters.

Beautiful single breeding:

Discus fish: The fish body is nearly disc-shaped and flat. The fish body color is rich and varied, including red discus with red as the main tone, brown discus with brown as the main tone, blue discus with blue as the main tone, and decorated with red, yellow, blue, green, black, brown, white, purple, etc., with a variety of colors and beautiful colors, known as the "King of Tropical Fish". Compared with other fish, it is not easy to keep.

You can also choose fish such as golden pineapple, black cloud, red pearl Guandao and pearl firemouth to match. In addition to the diverse body color matching, they can also achieve a state of peaceful coexistence under a certain balance. Large fish that can eat and defecate are easy to raise and not difficult to breed. Because the map fish is large, a larger aquarium must be selected when raising it. Because this fish has a large appetite and a strong excretion ability, it grows very fast and can be matched at will. Seven-star knife fish, also known as archback fish, seven-star flying knife fish, Oriental knife fish, and flower knife fish. Distributed in India, Myanmar, and Thailand. Silver Arowana: Silver Arowana is easier to raise but not easy to breed. The difference between male and female broodstock mainly depends on the pelvic fins. The longer and sharper one is the male, and the female fish has a swollen abdomen. Male fish sexually mature for more than 5-6 years, and female fish for more than 6-7 years. They have a strong self-selection mate characteristic. Breeding requires weakly acidic soft water with high oxygen content and a water temperature of 27-28℃. There are also seven-star knife dragon red-tail catfish. If you have the skills, you can raise seven-color golden dragon fish. It depends on your financial strength.

To be honest, large fish are either good-looking but difficult to raise (golden dragon, red dragon), or easy to raise but not good-looking. If you want to compromise, I think the silver dragon is the best one for both raising and looking good! There are also walrus fish, which are huge! You need to prepare a tank of more than 2 meters, haha! The lucky crocodile and the anti-sky knife are also good, but they are more fierce and not suitable for mixed breeding!

Here is what the fish looks like:

1. Non-Silver Dragon

2. Sea leopard fish

3. Lucky Crocodile

4. Anti-Tiandao fish

Simply put, I like to say it very simply and directly so that you can understand

To be honest, large fish are either good-looking but difficult to raise (golden dragon, red dragon), or easy to raise but not good-looking.

Silver dragon, sharp-nosed crocodile, seven-star knife, map, walrus, paparazzi, whale, tiger shark, these are all medium to large fish that are easy to raise, and they are very cheap. Except for walrus and silver dragon, the other 20 cm young fish do not exceed 50 yuan. Walrus young fish cost about 400 yuan, and silver dragon about 100 yuan!

I raise a silver dragon seven-star knife-pointed mouth tiger shark, which is relatively easy to raise! I hope this can help you

The colorful map parrot looks good but I don't recommend it. I keep a Luohan at home. The water temperature is kept at 25 to 30 degrees. It is filtered 24 hours a day and the water is changed once or twice a month. It has been two years and has not been sick once. I usually feed it. Now except for the color of the body, everything else is fine (Note: I am a lazy person)

How to raise freshwater tropical fish

Hello, tropical freshwater ornamental fish have slightly different breeding methods depending on the species. Since you did not specify what kind of tropical ornamental fish you want to raise, I can only tell you the basic knowledge of raising tropical ornamental fish. If you need, you can send me a message directly. I will help you answer in time.

1. The fish tank must be sterilized before use (brush it with high-concentration potassium permanganate water, then soak the fish tank with low-concentration potassium permanganate water for about a day, salt water is also acceptable)

2. Choosing the right fish is also very important. Sometimes the fish you bring home are already sick. (This requires a lot of experience)

3. When you bring the new fish home, make sure the water temperature in your fish tank has reached a temperature suitable for the growth of your fish (26 degrees plus or minus 1 degree is more suitable for tropical fish, but this is not an absolute value). Do not open the bag, put it into the fish tank with the bag, let it float for 10 to 20 minutes, then pour the fish back into the tank, do not feed it within three days. After that, feed it twice a day, and it is best if the fish finish eating within five minutes each time.

4. Change the water. For those without a filter and oxygenation system, change about one-fifth of the water every day. For those with a filter and oxygenation system, change one-third or one-half of the water every three days. Be careful not to use tap water that has just been connected. After the tap water is connected, it is best to leave it for two or three days before changing it for the fish. This is because tap water contains a lot of substances that are harmful to fish. Another thing to pay attention to is the water temperature control when changing the water. The temperature of the new water and the water in the original tank should not differ by more than plus or minus 1 degree.

5. Pay attention to the oxygen consumption of small fish. If there are many fish, you need to add oxygen pumps to provide oxygen.

6. When the fish is sick, go to the fish store to consult about the medication. (Consult several stores to increase experience and prevent being cheated.)

Can't be too hot...

When raising tropical fish in large quantities, it is necessary to feed 2-3 times a day; for breeding fish in the breeding period, it is generally fed 3-4 times a day. Because tropical fish are small in size and have limited appetite, it is appropriate to feed 70-80% full each time. Increasing the number of feedings will promote rapid growth of turtles. Most species of tropical fish are mainly fed with turtle worms. When the bait is mainly worms, the amount of feed should be controlled to be eaten within 10-30 minutes. When the bait is mainly earthworms, the amount of feed should be controlled to be eaten within 5-10 minutes. Each person feeds 2-3 times, and the earthworms fed should be rinsed clean. When the bait is mainly small fish and shrimp, in principle, more meals should be fed less. When tropical fish change new bait, the amount of feed should be gradually increased from less. Tropical fish should stop feeding for 1-2 days before transportation.

3. Water use

(1) Adding water: Adding water means partially changing the water. This is a simple and effective method often used in tropical fish breeding. Before adding water, turn off the power of the heater, air pump, circulating filter pump and other electrical appliances in the aquarium, then use gauze to wipe the moss attached to the glass or scenery on the four walls of the aquarium. After the water is left to stand for 15 minutes, all the suspended matter in the water will sink to the bottom of the tank. Use a rubber hose to gently suck out the dirt at the bottom. Generally, the amount of water sucked out accounts for about 1/4 to 1/3 of the total water volume. Then slowly inject the prepared new water of the same temperature along the wall of the tank.

(2) Water change: water change means to replace all the feeding water. It is the simplest and most effective way to change the water quality. However, it is a lot of work, especially when the aquarium is small and has scenery. The process is complicated and tedious. Before changing the water, cut off the power supply of all electrical appliances in the aquarium, take out all the fish and scenery, and drain the water. After rinsing the aquarium, put away all the scenery and put in new water for later use.

4. Temperature control

(1) Temperature range: Most species of tropical fish can live in the range of 20-32℃, and only a few species can tolerate water temperatures above 18℃. Generally, the most suitable water temperature for tropical fish is 24-26℃, but different species of tropical fish have different requirements for water temperature, especially breeding fish, which often need high water temperatures of 27-30℃. Reason: There is a certain temperature limit for the survival of tropical fish. In most areas of my country, the natural temperature is difficult to meet its physiological needs, so there is a problem of how to keep warm.

(2) Insulation methods: There are two methods for keeping tropical fish warm: one is to directly increase the water temperature; the other is to indirectly increase the water temperature by increasing the room temperature.

Aquariums for tropical fish at home usually use the method of directly increasing the water temperature, that is, putting the heater directly into the aquarium. The heater is mostly made of glass tubes or stainless steel tubes. Common heating tubes that can be used for heating include ordinary heating tubes and automatic temperature-adjusting heating tubes. Generally, an aquarium with a water capacity of 100 liters requires a 100-watt heating tube. Temperature-controllable heating tubes can be used for home ornamental fish aquariums. When the water temperature reaches the set temperature, the heating tube will automatically stop working.

Indoor greenhouses for mass production of tropical fish are mostly coal-fired or heated, which indirectly ensures stable water temperature by keeping the room temperature constant. In a greenhouse, due to uneven heat dissipation, the temperature of the upper space is higher, the temperature of the lower space is lower, and the temperature near the radiator is higher. Aquariums in a greenhouse are generally arranged in three layers: high, medium, and low, to raise tropical fish with different water temperature requirements.

The water temperature in a tropical fish aquarium should be stable, but it does not mean that the water temperature is completely constant. Tropical fish can usually tolerate a daily temperature difference of 3-5℃, so the water temperature of the feeding water is allowed to have slight changes or a slow rise or fall. However, tropical fish cannot tolerate a sudden change in water temperature in a short period of time, so the water temperature in the aquarium should rise slowly.

No matter which method is used for heat preservation, the aquarium should be equipped with oxygenated circulating water equipment so that the tiny bubbles emitted by the air pump can evenly spread the heat to avoid the temperature of the heating point being too high. Electric heating tubes are used for heating in aquariums. Ordinary electric heating tubes cannot be completely immersed in water. Some electric heating tubes with automatic temperature control can be completely immersed in water. They are adsorbed on the wall of the tank or lying on the bottom of the tank before turning on the power. When the electric heating tube is working, bubbles will constantly escape from the outer wall of the tube into the water. When taking out the electric heating tube, turn off the power first, and wait for the electric heating tube to cool down for a period of time before taking it out to prevent the electric heating tube from bursting due to uneven heating.

5. Dimming

Most species of tropical fish do not require strong light. In daily breeding, the effect of light regulation is not obvious. However, during the breeding period, some species require dim light, while others require strong light. Ornamental aquariums are sometimes also often illuminated with special lights to achieve a higher ornamental effect. Family ornamental fish aquariums are rarely placed in direct sunlight, because direct sunlight can easily cause algae in the water to multiply rapidly, causing the glass tank wall or the leaves of water plants to be covered with moss, reducing the ornamental effect.

After planting aquatic plants in the aquarium, it is necessary to control the light because the plants have certain requirements for the intensity of light. Some aquatic plants need stronger light, such as water lilies. Some aquatic plants need dim light, such as water celery. The aquatic plants that need weak light are: bamboo orchid, water celery, crown grass, orchid grass, etc. The aquatic plants that need stronger light are: goldfish grass, water lily, banana grass, water fruit, and water celery.

Artificial light sources include incandescent lamps and fluorescent lamps, and fluorescent lamps are commonly used. Artificial light sources should be installed above the fish tank so that the light shines from top to bottom. In this way, when viewed from the front, the plants, trees, and fish in the aquarium are very clear, and the viewing effect is very good. Underwater colored lights are also often used in home aquariums to create landscapes. The lights in the aquarium are generally turned on for a few hours a day to meet the light requirements of tropical fish and aquatic plants.

6. Cultivation of juvenile fish

Fry refers to the fry that has grown and developed into individuals similar to adult fish. Their fins are obvious, the body color is basically bright, and there is no big difference in appearance from adult fish. Generally speaking, fry enter the juvenile stage after 4-5 weeks of feeding, and fry generally mature after 4-5 months of feeding. The key point of fry cultivation is to provide them with a good living environment so that the fry can grow quickly.

The feeding of juveniles is basically the same as that of adult fish. In view of the rapid growth of juveniles, the stocking density should be continuously reduced during their growth. The amount of feed for juveniles should be controlled so that the feed can be eaten in 10-20 minutes, and the number of feedings should be controlled at 2-3 times a day. Juveniles mainly feed on fish and insects, and their abdomens swell after being full. The normal color of juvenile feces is black or gray-black strips. If the color is milky white, it indicates that the juveniles have indigestion and the amount of feed should be reduced. Juveniles have a strong appetite, and their metabolic products also increase. There will be a large amount of residual bait, feces, etc. at the bottom of the aquarium every day. If not handled in time, these metabolites will rot and damage the water quality. The simplest way to maintain the water quality of juveniles is to regularly turn on the circulating water filtration equipment. Secondly, you can also use a plastic hose with a diameter of 3-4 cm, gently probe into the bottom of the tank, use the siphon principle to suck out all the dirt at the bottom of the tank, and then add the same amount of new water at the same temperature. Water quality treatment for tropical fish is a regular job.

The feeding water for young fish generally needs to be completely replaced every 10-15 days. The water temperature of the feeding water is mostly controlled at around 25℃, and the daily temperature difference should be controlled at around 2℃ as much as possible. If the water temperature of tropical fish changes by 2-5℃ in a short period of time, the young fish are very likely to get sick, so the water temperature of young fish should be prevented from being hot and cold. For large species of tropical fish, their young fish grow rapidly, so the stocking density of a single tank should be reduced regularly, and the types of bait should also be rotated regularly.

Feeding Scenery

Aquarium setting:

1. Tropical aquatic plants

(1) Crown grass: This is a large, broad-leaved aquatic plant that is widely distributed in South America, Brazil, Argentina, Uruguay, etc. It has a thick stem base, high petioles, and broad leaves. At the base of the stem, 10 to 20 broad leaves grow, arranged in a lotus shape. It is known as the "king of tropical aquatic plants." Crown grass mainly reproduces by running stems and extending to the water surface. The plant is divided into male and female. Usually, 3 to 5 leaflets sprout from the base of the female root. After transplanting, the crown grass can become a crown grass.
