1. How to raise tropical fish?

1. Breeding environment

It is very important to have a suitable water temperature, so a thermometer should be prepared. In order to maintain the water temperature, an automatic heating device is also needed. The fishing net should be soft and square. The water tank should be equipped with an air pump to make the water flow, drive out carbon dioxide in the water, and increase the oxygen content in the water. A filter can also be installed on the bottom plate of the aquarium to absorb food debris and feces in the water.

The bottom of the aquarium is covered with sand, calcareous limestone, crushed oyster shells, crushed corals, etc., which is conducive to creating a suitable environment for tropical fish.

2. Water temperature

Tropical fish can be kept in an adaptable temperature between 22 and 28 degrees Celsius. When changing the water, remember to keep the water temperature consistent with the water temperature in the grass tank. The temperature difference is too large.

3. Water Quality

Freshwater aquaculture can use tap water, but tap water needs to be left for more than 3 days before use. Use PH test paper to test the acidity and alkalinity of the water, and neutral water is appropriate. Marine aquaculture should use natural seawater, preferably at high tide, and the seawater should be free of pollution and oil stains.

4. Feeding

The baits for tropical fish include fish worms, water earthworms, fiber worms, mealworms, small live fish, pellet feeds, etc. There are many varieties of tropical fish, so the bait choices for different varieties of tropical fish are also different. Most tropical fish are mainly fed with animal baits, and small varieties can also be domesticated to feed mainly with pellet feeds, while there are very few fish that are mainly fed with plant baits.

The amount of feed should be determined according to the size and number of fish. For tropical fish raised at home, it is generally only necessary to feed 1-2 times a day, and the amount of feed should be enough for the fish to eat within 5-10 minutes.

5. Change the water

There are two methods: partial water change and full water change. Partial water change is to use a straw to suck out the feces, leftover bait and other dirt at the bottom of the fish tank. The amount of water sucked is preferably 1/4 of the water in the tank. Then add the same amount of new water at the same temperature that has been aired or chemically dechlorinated. The frequency of water change is preferably twice a week in autumn and winter, and three times a week in spring and summer.

Complete water change means taking out all the equipment in the fish tank, taking out the water plants and fish, and placing them in another container with the same temperature as the original water, and using a sponge to clean the tank wall and bottom. Change the water once every 2-3 months.

2. How to breed tropical fish How to breed tropical fish

1. Water temperature

Tropical fish are extremely sensitive to temperature. If the temperature is not suitable, they will die soon. Different types of tropical fish have different requirements for water temperature. The water temperature for most tropical fish is preferably 20℃ to 24℃. The water temperature during the breeding season is preferably 25℃ to 28℃. The temperature difference between day and night cannot exceed 4℃.

2. Oxygen

A certain amount of water plants should be planted in the fish tank, because aquatic plants produce oxygen during photosynthesis, which increases the oxygen content in the water. At the same time, timely removal of dirt and frequent water changes can also increase the dissolved oxygen in the water.

3. Lighting

Place the fish tank in a sunny room, preferably in the morning and evening when the sun is insufficient, and expose it to sunlight for about 1 hour each; if you place the fish tank in a room without sunlight, you should use light to illuminate the water plants, using a 60-watt incandescent bulb or a 40-watt fluorescent lamp for 6 hours a day. Light can make tropical fish grow faster and make the fish more colorful.

4. Free range

The stocking density of tropical fish in a tank depends on the size of the tank. For first-time fish keepers, the lower the density, the better, and an air pump is needed. For the combination of fish in the same tank, quiet fish cannot be kept together with aggressive fish; large fish cannot be kept together with small fish. There are many choices of tropical fish feed, such as fish worms, bloodworms or packaged feed suitable for different types of tropical fish. Raw bait and live bait must be cleaned to control the source of disease.

3. Breeding of tropical fish

Tropical fish attract many people with their colorful characteristics. The key is that tropical fish are easy to raise and suitable for novices to raise. The following is the relevant content about tropical fish breeding that I have compiled for you, I hope it can help you.

Essential equipment for raising tropical fish 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.

Key points for tropical fish breeding 1. Avoid direct sunlight for long periods of time in indoor aquariums, otherwise hairy blue-green or blue-black low-grade algae will grow on the stems and leaves of water plants, the walls of the aquarium, and the bottom, making the aquarium tasteless and even dirty. To avoid this unpleasant phenomenon, draw the curtains when the weather is fine, or use green transparent paper to block the sunlight from shining into the aquarium. Generally speaking, there are not many such algae in clean aquariums with few fish.

2. The water temperature for tropical fish is generally between 20 and 30 degrees Celsius. However, different species of tropical fish have different requirements for water temperature. For example, guppies, red swordfish, black mollies and other fish can tolerate water temperatures of around 10 degrees Celsius without dying, while swallowfish, tiger barbs and other fish will die when the water temperature is below 18 degrees Celsius. Most tropical fish are very sensitive to water temperature. If the water temperature changes by ±2 degrees Celsius, they will catch a cold. If the water temperature fluctuates for a long time, the fish will suffer from various diseases. Therefore, try to keep the water temperature constant.

3. The lighting equipment for tropical fish is mainly fluorescent lamps, in addition to halogen lamps, mercury lamps, etc. Underwater color lights can sometimes be used to illuminate a single aquarium. It is a small glass-enclosed lamp tube that can be placed directly underwater and adsorbed on the glass tank wall. The lamp tube can emit different colors, such as red, blue, green, and white lights, which have a better landscaping effect.

4. Tropical fish feed includes fish worms, water earthworms, ciliates, mealworms, small live fish, pellet feed, etc. Tropical fish are of various species and sizes, so the bait selection for different tropical fish species is also different. Most tropical fish feed mainly on animal feed, and small species can also be domesticated to feed mainly on pellet feed, while fish that feed mainly on plant feed are rare.

5. The amount of food for tropical fish should be determined according to the size and number of fish. When raising tropical fish at home, generally only 1-2 times a day are needed, and the amount of food should be enough for the fish to eat within 5-10 minutes. When raising tropical fish in large quantities, it is necessary to feed 2-3 times a day; breeding fish in the breeding period are generally fed 3-4 times a day.

6. Changing water is the simplest and most effective way to change water quality, but 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 standby use.

How to breed tropical fish 1. Chasing breeding

The male and female fish lay eggs and fertilize them while chasing each other. Most of these fish are from the Cyprinidae and Characidae families. For example: red light, red skirt, zebra, golden silk, flat fish, etc.

2. Reproduction by wearing animals

The female fish first lays eggs on a flower pot, flat stone slab, glass plate or water plant leaf surface, and the male fish fertilizes them later. Such as: angelfish, swallowfish, map fish, sapphire fish, firemouth fish, seven-color phoenix and other cichlids.

3. Nesting and reproduction

The male fish inhales air and mucus from its mouth to produce foam, which is then spit into the water surface to form a nest. The male and female fish embrace each other and lay eggs in the foam for incubation. Examples include: horse pangolin, blue star, Lili, Thai fighting fish, etc.

4. Suspension breeding

Male and female fish lay eggs suspended on the water surface for incubation. Examples include kissing fish and lion fish.

5. Nest building and breeding

When breeding this type of tropical fish, the bottom of the tank must be covered with gravel. When breeding, the male fish takes gravel into its mouth with big mouthfuls, and then spits it out to dig a nest of the same size as the fish body. The male and female fish lay eggs in the nest and wait for breeding. Examples include: Tilapia, Blue Rainbow, African Phoenix, etc.

6. Oral fertilization

After the female fish lays eggs, it immediately holds the eggs in its mouth. At the same time, the male fish releases sperm, which enters the female fish's mouth for fertilization and hatches in the mouth. For example: mouth-hatching fish, red tilapia, pearl fish, etc.

7. In vivo reproduction

These fish produce fully grown fish fry instead of roe, such as red arrowtail, black mollies and guppies.
