What is the temperature required to raise tropical fish?

How to raise tropical fish

Water quality: People living in cities mostly use tap water to raise tropical fish. It is basically neutral water, and its hardness and pH are suitable for raising tropical fish.

However, when using tap water to feed tropical fish, the chlorine must be removed.

The main methods are drying and chemical methods. The drying method is to dry the selenium in the sun for two days, or in a dark place for 4 to 6 days before use. Chemical method

Use sodium thiosulfate to remove chlorine, the ratio is 1 gram of sodium thiosulfate per 10 kg of water, stir and dissolve, then it can be used.

There is a water stabilizer that is also a good choice, but it is a bit more expensive.

Water temperature: Temperature is the most important condition for tropical fish to survive. Tropical fish are stenothermic animals and are extremely sensitive to temperature.

If the temperature is not suitable, they will die soon. The water temperature for tropical fish should be between 20 and 30 degrees Celsius.

Hairtail fish have different requirements for water temperature. For example, guppies and swordtail fish can tolerate low temperatures of around 10°C, while angelfish and tiger fish can tolerate low temperatures of around 10°C.

Fish such as mullet will die when the temperature is below 18℃. Therefore, to keep passionate fish well, you must control the water temperature to make it suitable for tropical fish.

Growth. The water temperature for most tropical fish is 20-24℃ for growth; the water temperature for breeding is 25-28℃, and the temperature should not exceed 4℃ during the day and night.

Otherwise, it will affect the growth of tropical fish. The water temperature should be kept constant during breeding, which will be more conducive to the production of broodstock and the hatching of eggs.

and growth of juveniles.

Light: Light is also very important for tropical fish. It has three main effects on tropical fish breeding.

The most important factor for plants to carry out photosynthesis. Without light, aquatic plants cannot carry out photosynthesis, but there is a limit to the amount of light.

If the light is too strong, the branches and leaves of the water plants will grow green moss, affecting the photosynthesis of the water plants. However, if the light is too weak or the lighting time is too short, the water plants will not be able to function properly.

The branches and leaves of the grass will turn yellow or even die due to insufficient photosynthesis. Place the fish tank in a sunny room, preferably in the morning and evening when the sun is not too strong.

If the fish tank is placed in a room without sunlight, the water plants should be exposed to sunlight for about an hour.

, use a 60-watt incandescent bulb or a 40-watt fluorescent lamp for six hours a day. Tropical fish also need light to grow and multiply. Light can make

Tropical fish grow faster, their bodies become more colorful, and their reproduction cycle is shortened.

The second function of light is to facilitate our viewing. Without light or too weak light, we cannot see clearly what is in the fish tank.

If you don't have the scenery, you won't be able to see it through.

The low temperature is between 18 and the high temperature is between 32. Generally, tropical fish need a temperature between 21 and 27 degrees!

24-26 degrees Celsius When treating diseases, a high temperature of 28-30 degrees Celsius is required

The lowest temperature is 18 degrees, and the fish just don't like to swim. The best temperature is 25-26 degrees.

It is dangerous if the temperature is below or above 21-30 degrees!

For some fish, such as peacocks, it’s fine if the fish’s temperature is above 18, but for the lotus lanterns, there will be problems if the temperature is below 20!

The lowest survival temperature is generally 16 to 18 degrees, and the best condition is generally 20 to 28 degrees! The highest can reach 32 or 33 degrees! You can check this comparison online!

The lowest temperature is a conservative estimate! The fish that can tolerate the lowest temperature is the guppy, which is said to be able to survive at 13 degrees! This is the healthiest and strongest fish!

Is it better to keep tropical fish or freshwater fish?

It depends on personal preference. Let me analyze it for you.

1. The concept of tropical fish. Originally, tropical fish were fish species in Southeast Asia, South America and the Amazon with an average water temperature of more than 20 degrees in their native habitats. However, the concept of tropical fish has gradually shifted, and all fish that are ornamental are classified as tropical fish. Therefore, many people who are not very professional now think that tropical fish = ornamental fish.

2. According to everyone's fish-raising habits, I will classify them into categories.

A. Marine fish, I won’t explain this in detail.

B. Tropical fish, just treat them as the ones commonly seen in aquarium stores

C. Color-producing native fish, such as male goby, Q, Guodou, beautiful loach, striped two-bearded fish...

D. Fierce native fish, with strange appearances and generally no special colors, such as Channa bream, Channa bream, sturgeon, catfish, mandarin fish...

E. Freshwater fish are fish that live near the mouths of rivers and can survive in both fresh and sea water. They are usually gobies or sea dragons.

F. Aquatic life. This is not what you asked about, so I won't go into details.

3. Native fish are not very ornamental, but they are resistant to low temperatures and are relatively hardy and easy to take care of compared to other fish.

The reason why tropical fish are called tropical fish is that they need to maintain a certain temperature to avoid death from excessive low temperature. They need equipment to maintain their living environment and are more sensitive to changes in water quality. However, after a long period of artificial cultivation and domestication, they are more adaptable to urban water quality than other fish. They are also highly ornamental, and almost all colors can be found. Food is also convenient. If a fish store sells fish, it will definitely have fish food.

I am not sure about marine fish, after all, it is a very profitable activity, and young people are not that enthusiastic about it. But it is definitely the most troublesome and the most expensive.

If it is a big company, they will have a marine tank, and if it is freshwater, they will raise high-end fish such as dragons and arowana; if it is a small company, they can add some small tropical fish to enhance the atmosphere for a more elegant look; if it is for yourself, you can raise whatever you like.

I have four tanks, one tropical, one goldfish, one goby, and one native. If you need more information, please contact me.

Local freshwater fish are large and quiet, so they are suitable for still water. If you use a still water pump to filter the water, the water flow will be too large, and if you don't use it, the water will easily become dirty. Tropical fish are mainly a problem of temperature control. If you use a still water device, you don't need to change the water frequently.

It depends on what fish you raise. If you have a small fish, add an oxygen pump, a heater, and a water temperature between 25-29°. Then you need a filter. The water should be old for a few days so that harmful substances can evaporate. It is best to change the water every 7 days, and pump out 1/3 of the water each time. If you raise large mixed fish such as map fish, come back every night to pump out the feces and magazines at the bottom of the tank. Don't pump too much, and wash the filter cotton. This will keep the water clean. Feed the fish twice a day, once in the morning and evening, and feed 70% of the water each time. If you have time, you can search for videos online. There are videos that specialize in raising tropical fish. I have seen them. They are good. They are taught by a woman. If you have never raised fish, I don't recommend raising dragons, arowana, or seven-color fish at the beginning. If you want to raise large fish, start with map fish, parrots, and lucky fish. If you want to raise small fish, start with swallow fish and red-green lights. This way, it won't be a big investment if they die. With experience, it's not too late to buy dragons and the like.

This question is really interesting.

The counterpart of tropical fish is common goldfish or other

The opposite of freshwater fish is marine fish.

I haven't figured this out yet. I'd better do my homework before asking.
