How to raise fairy fish?

Fairy fish diseases, insects, swallow fish, angels, little fairy fish, small fin sailing fish, etc., are almost synonymous with tropical fish. as long as tropical fish is mentioned, people's first association is this kind of fish that shuttles leisurely through the aquatic plants and is so beautiful that it is unparalleled by any kind of tropical fish. let's take a look at how to raise fairy fish.

Fairy fish breeding environment

The fairy fish is very gentle and has no special requirements for water quality. It can be mixed with most fish in the environment of weak acid water quality. The water temperature is generally controlled between 24 and 28 ℃. In this temperature range, the fish has a strong appetite, grows rapidly, is not affected by changes in external air temperature, and is always maintained in a relatively stable state. Can be mixed with other tropical fish, the only thing to pay attention to is the cyprinid tiger skin fish, these naughty and lively small fish often like to bite the anal fin and caudal fin of fairy fish, although it is not a fatal attack, but in order to maintain the beautiful appearance of fairy fish, try to avoid mixing fairy fish with them.

Bait management of fairy fish

1. Feeding habits: the diets of fairy fish are fish and insects, water earthworms, ciliates, yellow powder worms, small live fish, pellet feed and so on. For the fairy fish with a body length of 3cm to 12cm, the bait is mainly tortoise worms, supplemented by water earthworms, red insects and yellow powder worms. For fairy fish with a body length of more than 12 cm, turtles are small and palatable, so they should choose bait with slightly larger individuals, such as red worms, water earthworms, yellow powder worms, small live fish and so on.

2. Bait: the feeding amount of fairy fish should be determined according to the size and quantity of the fish. Family raising fairy fish generally only need to bait twice a day, and its feeding amount should be eaten within 5 minutes. When raising fairy fish in large quantities, bait is needed 2 times or 3 times a day. Breeding fish during the breeding period, usually bait 3 times or 4 times a day. Due to the small size and limited food intake of fairy fish, it is appropriate to feed 7-8% each time, and increase the feeding times to promote the rapid growth of fish.

Water quality management of fairy fish

1. Mixing water: mixing water refers to the partial change of water, which is a simple and effective method often used in the breeding of fairy fish. Before mixing water, turn off the power of the heaters, inflatable pumps, circulating filter pumps and other electrical appliances in the aquarium, then wipe off the moss on the four walls of the aquarium or the scenery with gauze, and wait for the water to sit for 15 minutes. all the suspended matter in the water sinks to the bottom of the cylinder and gently sucks out the dirt at the bottom with a rubber tube. The amount of water sucked out accounts for about 1% of the total water, and then the prepared new water of the same temperature is slowly injected along the cylinder wall.

2. water change: water change refers to the total replacement of feed water, which is the most simple and effective way to change the water quality, but the workload of changing water is large, especially when the aquarium is small, the process is complex and tedious. Before changing the water, cut off the power of all the electrical appliances in the aquarium, take out all the fish and scenery, and release the water. After rinsing the aquarium, put all the scenery away and put it in fresh water.

Prevention and control of diseases and pests of fairy fish

1. Anchor head worms: after the anchor head worms pierce deeply into the body tissue of the fish, they stick themselves firmly to the fish and can pick off the adult worms one by one, but this is a long process and potentially harmful to the fish. Short-term soaking in 3% salt solution can also remove worms from fish, repeated use of anti-protozoan treatment agents in ponds can kill larvae, and trichlorfon can also kill adults.

2. Black spot: small black or brown spot, up to 2 mm wide, appearing on the body and fins, and sometimes on the eyes and mouth. New anti-parasite treatments can kill parasites, but once black spots are formed, they leave traces. The most effective prevention is to break the parasite growth cycle by ensuring that waterbirds do not go near ponds or aquariums and that there are no parasitic snails.

3. Blood flagellate: the fish infected with Cryptosporidium are listless and swim abnormally. the fish become thin, their eyes are sunken, their gills are white, and the severely damaged fish die. At present, no chemical treatment agent has been found to effectively control hemoglobin flagellates in ornamental fish. Since only the fish attacked by leeches are infected, only the infected fish need to be removed and the leeches removed. But it's pretty easy to do this in an aquarium, and it's much more difficult to solve the problem in an infected pond.

4. Oblique tube worms: the affected fish rub against hard objects, close their fins, and their skin is covered with a whitish blue opacity, especially between the pass and the dorsal fin. If the Gill is invaded, the frequency of breathing increases significantly. In the late stages of infection, the surface of the skin swells and then falls off. If the fish are strong, the best treatment for freshwater fish is to soak them in 3% salt water, leave the fish inside until curled up, and then quickly put them back in their aquarium. Or you can use a new anti-parasite treatment agent.

5. Cloud eye disease: one or two eyes of the fish become cloudy and white, which may show signs of tension, and the color of the fish is abnormal, or they behave like normal fish. If it is a parasite infection, use the appropriate treatment. If the root cause of the disease is bacteria, use treatments that contain anti-bacterial compounds such as phenoxyethanol or furanas. Maintaining a good environment, especially clean water, can minimize the incidence of cloud eyes, because dirty water can be a cause, so adding a small amount of salt to the water can help prevent it.

6. Water mold: obvious signs of infection are cottonlike vegetations, usually white, but sometimes gray black to green, usually starting from the torso, but may also originate from a damaged area. can spread and invade fins, mouth, eyes and gills. Salt bath is a traditional treatment for freshwater fish diseases, but it can cause inappropriate irritation and requires frequent changes, and it is not particularly effective to use it alone. Methylene blue is effective in mild cases, but the prescribed dosage can color the water, making it difficult to continuously check the progression of the disease.
