Swallow fish, also known as angelfish, is very easy to raise. I have been raising swallowtail fish for 10 years. It seems that you are the first person to raise swallowfish. Let me tell you what time it is. If you want to raise (ink) swallows, that is, black swallowfish, you should do this more:
1, throw away all the fish
2, fish tank disinfection, salt can be used.
3. Put in fresh water for four to five days and heat it to about 25 degrees.
4. Pay attention to this. If the fish you bought is not sick, the temperature of the fish in the bag should be the same as that of the water in the tank when you put it in the tank (put the fish bag in the tank for a period of time).
5. Don't feed the bugs, feed the dry bait.
6. Don't change water frequently. It's good to master the rules for a while. It is easy to raise.
You will know after a long time. Do it.

Morphological characteristics of angelfish
Angel fish, also known as swallow fish, angel fish, cherub fish and pinfish, belong to Lycoris, and are native to Guyana and Brazil in South America.
The angelfish is12-15cm long and15-20cm high. Its head is very small, and its top is flat and diamond-shaped. The dorsal fin and the gluteal fin are very big, as tall and straight as a spinnaker, so they are called spinnakers. From the side, the angelfish swims like a swallow, so the angelfish is a swallow fish.
The ventral fin of angelfish has evolved into tentacles, white and soft, as long as tassels. The tail stalk is short, the tail fin has a straight trailing edge, and the upper and lower ends are slightly longer. The pectoral fin is colorless and transparent, and the body surface color is silvery white with yellow, the abdomen is silvery white, and the back is light golden yellow. There are four thick black lines on its side, the first one passes through the orbit, the second one is at the front edge of dorsal fin and the base of anal fin, the third one is from the end of dorsal fin to the end of anal fin, and the fourth one is at the base of caudal stalk. The iris of the outer ring of black eyes is red with a black velvet belt on it.
The angelfish is quiet and smart. It rises and falls in the water, enters and retreats, and floats like a fairy. It is known as the "Queen of Ornamental Fish" with its peculiar figure, graceful swimming style and elegant colors.
Feeding requirements of angelfish
Angel fish has a gentle personality and elegant swimming posture, and it is not difficult to raise. It requires that the feeding box should be large, and broad-leaved aquatic plants should be planted, and several hours of light can be obtained every day. Angel fish have no strict requirements on water quality, and like to live in weak acidic soft water with pH6.5-7.0, and the suitable temperature is 26-30 degrees Celsius. I advocate feeding nematodes with red worms and blood worms instead. In particular, cultured fish cannot use nematodes. Also, some fish friends use hamburgers, which are also very good. I just don't use them because I'm too lazy to cook. As long as you feed it twice a day and once in the morning, there should be some bait left in the jar so that you can eat it until noon. Feed it once in the evening and eat it within 1 hour! Change the water once a night (1 meter tank can change two pots of water! The replaced water will only be trapped for one day! ), you can raise them well! The most important thing is not to feed finished fish food, such as patches and small grains. I don't know the rest. I have a jar that has been used for half a year. The fish didn't die, but it just stopped growing.
Angel fish like dry fresh water, and changing water frequently will reduce their chances of getting sick.
Angel fish don't choose to eat, but they like to eat large fresh bait such as earthworms. Angel fish can be mixed with other tropical fish, but not with tiger skin fish, because tiger skin fish will bite the hip fin and tail fin of angel fish.
Male and female identification and reproduction of angelfish
It is difficult to tell the difference between male and female angelfish. Generally speaking, the head of female fish is smooth, and that of male fish is slightly convex; The abdomen of female fish is swollen, while that of male fish is normal; Females have shorter fins than males.
Angel fish is an oviparous fish, which reaches maturity at the age of 10 month. Angel fish have the habit of "free love" and seek companionship. If they are forced to "mate" against their will, it will often lead to reproductive failure. Therefore, we should pay attention to the observation after the angelfish enters the breeding period. If we find that two fish often swim and feed together, and their anus is drooping and protruding, we should salvage them to the aquaculture box prepared in advance. When both male and female fish are in estrus, a very thin vas deferens can be seen in the lower abdomen of male fish, which is pale white or yellowish white and about 0.5- 1mm long. The abdomen of the female fish will bulge, and at the same time, a thick fallopian tube with a length of about 1 mm will be applied to the lower abdomen, which is the same color as that of the male fish.
Angel fish like to lay eggs on the leaves of broad-leaved aquatic plants. If there are no aquatic plants, a frosted glass (or stainless steel, glazed tile or plastic plate) can be placed at the bottom of the fish tank to make it form a 45-degree angle with the tank wall as an attachment for laying eggs. At this time, both male and female fish will clean the frosted glass plate with their mouths, which is also commonly known as "licking the plate". Within 1-2 days, the female fish will lay eggs in the dish, and the male fish will fertilize the eggs. Repeatedly, it will take several hours to complete. Each female fish can lay 400- 1000 eggs per reproduction.
After laying eggs, male and female fish have the habit of protecting eggs together. They take turns fanning water on eggs with pectoral fins to provide oxygen for fertilized eggs to hatch. When unfertilized white eggs are found, both male and female fish will clean them up with their mouths. Don't mistake them for eating fish eggs.
Generally speaking, the culture water of angelfish should be pH6.5-7.4, hardness 7- 10, and suitable temperature 27 degrees Celsius.
The fertilized egg can hatch into larvae in 2 days. The newly hatched larvae can't swim, but continue to develop by absorbing the yolk sac and stay on the attachment for 1 week. During this time, the parent fish has been protecting the larvae. If a larva falls into the bottom of the fish tank, the parent fish will pick it up with its mouth and send it back to the attachment. Male and female parents sometimes fight with each other in the process of feeding eggs and fry. If this happens, the male fish should be fished out and taken care of the female fish alone.
After hatching 1 week, the larvae "go ashore, swim for food, and move in groups under the guidance of the parent fish." Parent fish must not be disturbed when feeding their larvae, otherwise they will devour fertilized eggs or larvae. 1 week, the parent fish can be fished out and raised separately. When the larvae begin to eat, it is appropriate to feed with "backwater". Small fish worms can be fed for 7 days, and the same bait as adult fish can be fed after 1 month.
Species of angelfish
After artificial hybridization, angelfish have formed many new species. Mainly include: golden-headed angelfish, the whole body is grayish yellow, without obvious black thick lines, the forehead is red and yellow, and the gill cover is transparent; Yuanyang angelfish is also called black and white angelfish. The first half is like an ordinary angelfish, and the second half is like a black angelfish. Marble angel fish, the whole body is gray, mixed with irregular black and white marble patterns; Black angel fish, with black body and underdeveloped fins; Glass angel fish, its whole body is translucent, gill cover is transparent, and red gills can be seen; There are red-eyed angelfish, grey angelfish, zebra angelfish, white angelfish and so on.
According to the length of fins, there are also long-tailed angelfish, middle-tailed angelfish and short-tailed angelfish.
Introduction to fish diseases:
1, melon disease is also called white spot disease.
[The pathogens are LEPIDOPTERA, LEPIDOPTERA, LEPIDOPTERA. This is a large ciliate. The morphology of larval stage and adult stage is very different. The larvae of cucurbitaceae attack the skin and gills of fish, especially the skin. When the larva infects the host, it burrows into the epithelial tissue of the skin or gill, wraps the body in the vesicles secreted by the host, grows and develops in the cells, and becomes an adult. The adult broke through the cyst and fell into the water. After swimming freely for a period of time, it will fall to the bottom of the water, stop and secrete a colloidal capsule. The worms in the capsule divide and reproduce, producing hundreds or even thousands of ciliated larvae. Larvae come out to swim freely in the water, looking for a host, which is the infection period of small melon worms. The larva infects a new host and restarts its life history.
【 Symptoms Ornamental fish are more likely to get sick due to cucurbitaceae parasites. At the initial stage of infection, there are white spots on the chest, back, caudal fin and surface skin of fish. At this time, the sick fish feed as usual. A few days later, white spots covered the whole body, and the fish lost the ability to move. They often appeared to be slow to move, floating on the water, swimming slowly, losing appetite, losing weight, bleeding spots on the skin, sometimes swinging from side to side, and swimming quickly sideways beside the aquarium walls, weeds and gravel, and gradually losing their balance. The course of disease is usually 5 ~ 10 days. Infection is very fast, and if it is not treated in time, it will cause a lot of deaths in a short time.
The suitable water temperature of Cucurbita moschata is 15 ~ 25℃. The disease mostly occurs in early winter, late spring and rainy season, especially in the absence of light, low temperature and live bait. When the water temperature rises to 28℃, the gourd will begin to die.
【 Prevention and control methods mostly adopt the weakness of small melon insects that can't withstand high temperature, increase the water temperature, and then combine with drug treatment. Usually the cure rate can reach more than 90%. If treated in time, the cure rate can reach 100%.
The mixed treatment effect of 0.05ppm malachite green and 25ppm formaldehyde solution is better. It can also be soaked in 1% salt water for several days, or soaked in 2ppm methyl blue solution for 6 hours every day; Or soak in quinine hydrochloride solution at 28-30℃ for 3-5 days, or soak in 2ppm mercurous nitrate solution for 30 minutes; Or soak in 50-70 ppm mercury chloride solution for 5- 15 minutes, or spray 0. 1-0.2 ppm mercury nitrate solution, all of which can achieve good results.
2. Trichinellosis
The pathogen belongs to Trypanosoma. Mainly parasitic on the skin and gills. The choice of host is not strict, and it is not limited to young fish or adult fish, but young fish are the most sensitive to this insect and often cause serious death. Small fish raised in small water bodies (such as aquariums) are easy to be invaded, and even a large number of deaths are found during long-distance transportation.
【 Symptoms The body of Trichinella spiralis is much smaller than the small melon worm, which is invisible to the naked eye and has no symptoms such as white spots. The infected part of the fish secretes a lot of mucus. In severe cases, the skin of the fish's focus area forms pale and blue-gray mucosa. Because the tissues of the skin and gills are destroyed, it is easy to be infected with bacteria. The sick fish became emaciated and black, the respiratory function was blocked, the appetite was lost, and finally they died. The suitable water temperature for Trichinella spiralis breeding is 65438 02 ~ 65438 08℃, which is easy to spread in winter and spring.
[The treatment method can be soaked in 8ppm copper sulfate solution or sprayed with 0.7ppm mixed solution of copper sulfate and ferrous sulfate (5: 2) in the aquarium, which can be effective.
There are many kinds of ornamental fish available for purchase in the flower, bird, insect and fish market, with different shapes and colors, which are dizzying. But can an inexperienced novice easily raise this beautiful fish? You know, some kinds of ornamental fish can only be raised by experts! In natural waters, most ornamental fish move in groups, so they can't be kept in aquariums in pairs. When raising most ornamental fish, there should be at least 6 ~ 8 fish in each fish tank. In this way, it not only suits their habits, but also has better viewing effect.
We will briefly introduce the most popular different kinds of ornamental fish as follows to help you buy fish.
Rat fish: Looking for bait at the bottom of the fish tank all day, like to flock and never keep it alone. Keep at least five together. Contrary to some claims, they are not "garbage pickers" in the aquarium, but like other ornamental fish, they also need high-quality balanced feed.
Lipid carp: mainly living in the middle layer of water, swimming in groups, very beautiful. When raising, the more fish of the same species, the better the ornamental effect.
Angel fish or seasonal fish: easy to raise, but never mix with traffic light fish, or traffic light fish will become their food.
Swordtail fish: It is very active and swims very fast.
Fish and water are learned.
Goldfish live in temperate regions, belong to wide-temperature fish, and have strong adaptability to water. Therefore, rivers, lakes, wells, springs and reservoirs can be used to raise goldfish. Although these waters are rich in plankton suitable for goldfish, they are easily mixed with aquatic insects and pathogenic bacteria harmful to goldfish, so measures such as filtration should be taken to avoid unfavorable factors. Well water and spring water contain many minerals, most of which are hard water. As long as they contain no toxic substances and pay attention to regulating the water temperature, they can also be used to raise goldfish. In cities, tap water is easy to get, contains few fungi, is harmless to people and animals, and is most suitable for keeping goldfish.
Tropical ornamental fish are produced in tropics and subtropics. The climate of the place of origin is hot, and the temperature difference changes little throughout the year, which is suitable for living in soft water. Therefore, the requirements for water quality are stricter than goldfish, and the hardness of tap water in all parts of China is within the range of 5 ~ 15. Measures should be taken to soften the water quality when raising tropical fish with tap water. However, for novice tropical fish, most of the cultured species are fish with strong adaptability to water, so you don't have to consider the hardness of water, just use the dried tap water directly. Of course, after accumulating experience in fish farming, you must pay attention to the softness and hardness of water when raising one kind of fish to several kinds of fish, especially tropical fish artificially, and adjust it to the most suitable value required by the breeding object, so that your fish tank will become more and more prosperous.
○ Fish farming rules
● The fish tank needs to be larger than the washbasin. Don't use small tanks to save money and love beauty.
● Raise water before raising fish, and add equipment such as filtration and oxygenation first.
● Don't be greedy when buying fish, it is better to squeeze less than to squeeze, and beware of lack of oxygen.
● Be careful when choosing fish. If you are slow and sick, no matter how good your appearance is, it is difficult to raise it.
● Fish farming needs to be lifted, and if it is abnormal, observe it first; If you take medicine at will, your kindness will not help.
1, don't worry about fish trauma, just apply mercurochrome.
2, fish diarrhea should be careful, hungry rice with furan, and then clear the water quality of food.
Don't lose heart when the fish turns over. Warm-up, shallow water, and hunger are still effective.
