CATDOLL : CATDOLL: Do tropical fish need to bask in the sun every day?

You don't have to sunbathe every day, but it is good to sunbathe more.

There are two benefits of getting more sun exposure: one is disinfection, and the other is that the fish body can have bright color.

Of course, you should avoid direct sunlight, which is very harmful to fish, and the water temperature is too high for fish to bear. It is best to use oblique light for 3-4 hours a day. Use fluorescent lamps evenly.

1. Essential equipment for tropical fish breeding

1. Fish tank: It is the place where tropical fish grow and move. The fish tank for raising tropical fish must be a slightly larger rectangular glass fish tank.

2. Suction pipe: It is used to suck out dirt from the bottom of the fish tank when changing water. It is made of a soft rubber tube and a glass tube. The length depends on the height of the fish tank. Generally, it is 1.2 to 1.5 meters.

3. Thermometer: used to measure and adjust the water temperature of the fish tank.

4. Fish net: used to catch and transfer tropical fish.

5. Glass lamp barrel: Put the bulb into the glass lamp barrel and sink it into the fish tank for heating and lighting. The mouth of the glass lamp barrel must be 100MM above the water surface to prevent fish from jumping in.

6. Electric heating tube: used to increase the temperature in the fish tank in winter.

7. Air pump: removes carbon dioxide from the fish tank and increases the oxygen content in the water.

8. Filter: Filter out dirt in the fish tank, keep the water clean, and play a dual role of increasing oxygen and purifying water.

9. Thermostat: used to automatically control the temperature in the fish tank and can keep the temperature constant for a long time.

10. Food bucket: prevents fish food from floating on the water surface, which is beneficial for fish predation. It can also prevent fish food from falling into the bottom of the water and drilling into the water plants, making the water plants and sand turn black and deteriorating the water quality.

11. Decontamination liquid: Made of plastic board. Used to scrape away dust and oil on the surface of the fish tank.

2. How to raise tropical fish?

First of all, we need to create a living environment for freshwater tropical fish. The geographical and climatic conditions of tropical and subtropical areas make tropical fish live in weakly acidic soft water with sufficient sunlight, high water temperature, small temperature difference and abundant natural food for a long time. Therefore, their growth, development and reproduction are closely related to water quality and water ecological conditions. When raising them artificially, it is impossible to achieve the same conditions as the waters of the tropical fish's hometown, but they must be provided with basic living conditions that they can adapt to, including water temperature, water hardness, water pH, etc.

How to raise tropical fish? --1. Water temperature conditions and adjustment methods

Tropical fish are stenothermic fish. They have strict requirements on water temperature and are particularly sensitive to changes in water temperature. They can adapt to water temperatures of 20-30 degrees. Exceeding the upper or lower limit of this range can be life-threatening for most tropical fish - if the water temperature drops below 20 degrees, tropical fish will get sick or die; although the water temperature reaches 20 degrees, if it is too low for a long time, it will also affect their appetite and growth; excessive temperature difference between day and night, such as exceeding 5 degrees, can also cause discomfort to them, which will lead to illness and death over time.

There are generally two ways to regulate the temperature of water used for fish farming: one is to directly heat the water in the aquarium, and the other is to indirectly increase the water temperature by raising the indoor temperature.

How to raise tropical fish? --2. Water quality requirements and adjustment methods

(1) Water hardness and adjustment methods

Most tropical fish require to live and reproduce in soft water and water with low hardness. The hardness of water is mainly determined by the amount of calcium and magnesium salts contained in the water. 8 degrees is soft water, 8-14 degrees is low hardness water, and 20-30 degrees is hard water. General rainwater and snow water are soft water; there are more red soils in southern my country, and the water hardness in the rainforest belt rivers is low, mostly soft water. The north has less rainfall, higher salinity and alkali content in the soil, and higher water hardness. Tropical fish are not as demanding on water hardness as water temperature, and can adapt to water with higher hardness. But when breeding, they require water with lower hardness or soft water.

Tap water is a common water source for breeding tropical fish. The easiest way to judge its hardness is to boil the water and look at the scale in the kettle. If there is more scale, it is hard water, and if there is less scale, it is soft water.

(2) Water pH and its adjustment method

The pH value of water refers to the concentration of hydrogen ions in the water. The pH value of water can be measured using pH test paper or a meter. Please refer to the instructions for use.

How to raise tropical fish? --3. Change the water

Fish have to constantly metabolize and excrete feces while they are alive. The bait for fish is also constantly oxidized and decayed, which will affect the water quality. Therefore, the water in the fish tank should be changed regularly and timely to keep the water fresh. Water change is divided into partial water change and full water change. Partial water change is also called water addition. Water addition means that the amount of water should be added according to the amount of water drawn out from the fish tank. It is not necessary to remove the fish and aquatic plants from the tank when adding water. Generally, the amount of water added should not exceed one-fourth of the total water volume of the fish tank each time. When adding water, pay attention to the temperature of the newly added water, and try to keep it consistent with the water temperature of the original fish tank. The number of times of water addition is one to two times a week in autumn and winter, and two to three times a week in spring and summer. The specific number of times depends on the turbidity of the water in the fish tank. If the filtration conditions are good and the water quality is clear, the number of times can be appropriately reduced. If the filtration conditions are poor, the number of times can be appropriately increased, but it should not be too frequent, otherwise the fish will get sick.

How to raise tropical fish? --4. Oxygen

Any living thing needs oxygen to survive. Without oxygen, there is no life. Tropical fish also cannot survive without oxygen. The oxygen needed for fish survival is obtained by absorbing dissolved oxygen in the water through the microvessels in the gills, and then brought to the body through the blood circulation system. Carbon dioxide is also discharged through the microvessels in the gills. The amount of dissolved oxygen in the water directly affects the growth of fish, so it is necessary to ensure that there is enough dissolved oxygen in the water. In addition to obtaining dissolved oxygen in the water by adding water and changing water, it can also be produced by photosynthesis of aquatic plants in the water.

How to raise tropical fish? --5. Bait selection and feeding method

Most tropical fish are carnivorous, a few are omnivorous, and very few are herbivorous. Carnivorous fish are divided into fierce and mild ones. Fierce ones have big mouths and fierce temperaments, and like to eat large pieces of food such as small fish, shrimps and earthworms, such as Texas leopard fish and dragon fish; mild ones have small bodies and small mouths, and like to eat small animals such as water fleas and midge larvae.

When feeding, you should feed selectively according to the fish's eating habits. The food you choose must be fresh. Natural food is best fresh, frozen food is also OK; artificial bait cannot be moldy or deteriorated. In addition, to avoid nutritional deficiencies, as long as the fish can accept it, the choice of feed should be as diverse as possible, and the variety of feed should be changed frequently.

After choosing the right bait, you must also master the correct feeding method to make it grow fast and well. When feeding tropical fish, you must also determine the feeding amount. The method of controlling the feeding amount is very simple, that is, feeding little by little. At the beginning, the fish will scramble for food, and you can stop when the fish are not obviously scrambling for food. If you feed too much at one time and the fish cannot finish it, it will remain in the water and affect the water quality. Generally speaking, feeding 1-2 times a day is enough. It is best to feed at the same time. If an aquarium wants to raise several kinds of tropical fish at the same time, you can feed them twice a day, once in the morning and once in the evening. Tropical fish can only have a good appetite when they grow in a suitable environment. Therefore, in addition to delicious food, you must also create an environment suitable for their growth. Factors such as low dissolved oxygen, inappropriate water temperature, and deteriorating water quality will affect the appetite of fish.

How to raise tropical fish? --6. Light

Light is very important for tropical fish to survive. Without light, tropical fish cannot survive. Light has three main effects on tropical fish breeding.

Light is the most important factor for all plants to photosynthesize. Without light, water plants cannot photosynthesize, absorb carbon dioxide and produce oxygen, and plants cannot maintain their own survival. However, plants also have certain limits on light requirements. If the light is too strong or the light duration is too long, water plants will grow green moss, which will affect the photosynthesis of water plants; but if the light is too weak or the light duration is too short, the branches and leaves of water plants will turn yellow or even die due to too little photosynthesis.

Reasonable lighting should be that in a sunny room, do not expose the fish to direct sunlight, and do not place them on windowsills or under windows. Use sunlight in the morning and evening for 1 to 2 hours. Of course, the time of using scattered light from the window can be appropriately extended. In a room without sunlight or insufficient sunlight, artificial light can also be used. A 60-watt incandescent lamp or a 40-watt fluorescent lamp can be used for about 6 hours a day. Tropical fish also need light to grow and reproduce. Fish with light grow faster, their bodies will be more colorful, and their reproduction cycle will be shortened.

The third function of lighting is to facilitate viewing. If you are in a dark room or a room with too little light, you will not be able to see the scenery in the fish tank clearly, and if you can't see it clearly, there is no point in viewing it.

3. Misconceptions about tropical fish breeding

1. Household spray insecticides are essential daily necessities for many families, but they are also a big taboo for fish breeding. Because these insecticides contain pyrethroids that are highly toxic to fish and shrimp, we cannot poison our beloved tropical fish because of them.

2. When using medicine to treat fish, the combination of some medicines may lead to failure or even poisoning of fish, which has serious consequences. Pay attention to formalin, which is corrosive and toxic. Quicklime should not be mixed with bleaching powder, fish health, fish safety, calcium, magnesium, heavy metal salts, organic complexes, etc.

3. Not paying attention to the properties and individual differences of the mixed species when raising them together will result in a mess. Tropical fish with different properties cannot coexist, and carnivorous tropical fish will bully or even eat herbivorous tropical fish.

4. Feeding depends entirely on personal preference. The fish may be full for one day and hungry for several days. This may cause the same population to be large and small due to malnutrition, or the fish may bite each other due to hunger and contract other diseases.

5. The fish tank is not placed properly, which will cause large temperature changes within a day, or moss will be all over the fish tank, and the dissolved oxygen will change greatly during the day and night. If you are not careful, gentle and steady during the operation, you will suddenly turn on or off the light, knock on the tank wall, and cause the tropical fish to panic or even hit the tank.

6. Not paying attention to the decorations in the fish box, and putting in some items that can change the water quality and produce toxic side effects: such as iron, copper, zinc, lead, mercury, calcium stone, etc.

The most important things to pay attention to when breeding tropical fish are water temperature, water quality and feed. If the water temperature and water quality are not suitable, it is most likely to cause various fish diseases. In addition, oxygen is also an important point. Only with sufficient oxygen can tropical fish be kept lively and the ornamental effect will be better.

What kind of environment do you keep it in? A small fish tank or a relatively large one?

Different environments require different treatment methods. If you expose the fish to the sun for a long time, there are two benefits: one is disinfection, and the other is that the fish body can be brightly colored. :)

Of course, you should avoid direct sunlight, which is very harmful to fish, and the water temperature is too high for fish to bear.

It is best to have 3-4 hours of oblique light every day. Fluorescent light can also be used. It should be even.

My experience over the years is that goldfish and tropical fish should not be exposed to the sun. Goldfish and tropical fish will die. Ordinary lighting is enough.

Fish exposed to sunlight will change color and affect their appearance

No, just aerobic exercise is fine.
