1. There are many bloodshot spots on the tail edge of guppy.

Answer: For bacterial infection caused by poor water quality, soak in 3% salt water 10 minute. If the condition is serious, the concentration should be reduced to 1%]. 1~ twice a day.

Keep the water clean, and the broken parts will fall off automatically in a few days. You can also pick up the fish and put potassium permanganate on the tail with a cotton swab.

2. Peacock's tail suddenly becomes thinner?

Because the water quality is not good, change one-third of the water every day to isolate and remove sick or healthy fish; Put 0.25~0.5PPM of oxytetracycline or chloramphenicol or 0.2~0.5PPM of furazolidone into the tank for five times (once every other day) without changing water.

3. What should I pay attention to when changing water?

A: Pay attention to water quality and water temperature! If it rains, reduce the change of water and add a small amount of furacilin to prevent diseases.

Peacocks began to rot, one by one, mixed with silver sharks, traffic lights, panda rats and lichen rats. What medicine did you use? Did the drugstore have it?

Answer: Use some furacilin and heat it. Sick fish should be quarantined. If it is not contagious, don't put too much, or the fish will die. When it turns yellow, the sick fish should be separated.

5. The fish shrinks its tail. At the bottom of the tank, sometimes you eat and sometimes you don't eat.

A: Rotten fin disease

Often due to overfeeding, changing water for a long time, the water quality deteriorates, resulting in fin edge falling off and slow action. Because of the sudden change of water quality, male guppies tend to shrink their wide triangular tails into a tail.

Change half the water first, and then treat it after 5-8 days. To raise guppies, we should first change water frequently, and regularly clean the filter cotton to avoid the breeding of germs.

2. The problem of peacock fish reproduction:

1 How big is a fish's stomach to be a small fish?

Answer: when the abdomen is black, you can almost see the small fish (fetal point) inside, and when the anus is lifted again, it will be born! Prenatal birth canal is slightly open, right-angled, with obvious reproductive holes protruding, so the size of the stomach may be inaccurate.

What do small fish feed after they are born?

Egg yolk water, chopped red worms, dry feed and live fish will grow faster.

3. When should fish grow fastest and stop growing?

A: Two months after birth, the little fish grew up, and then it began to grow up slowly. At this time, it began to approach the adult fish, and the tail and dorsal fin became bigger and longer, and the color became more gorgeous. Small fish are basically stable from half a year after birth.

4. How to prevent female fish from dystocia?

Answer: don't scare it, drink water and feed it well, and stimulate it with fresh water when you are ready to be born. It's normal not to exercise because your stomach is too big. Peacocks will not die, but it is easy to have poor water quality if they are fed too much.

5. Excuse me, why are half of the small fish born by my peacock still eggs? Didn't you say it was viviparous?

A: Incomplete fertilization or fertilization but poor development may also be too close to blood or malnutrition. Avoid sudden changes (sudden changes in temperature and water quality and human shock) and eat with good feed.

6. How to divide men and women?

Answer: The correct way to distinguish guppies from males is through the copulatory organ behind the ventral fin, and other characteristics such as the size and bright color of the caudal fin can be used as an auxiliary discrimination; Female fish are judged by fetal spots. Larvae can't be divided into males and females until fetal spots appear, which takes about a month. If a virgin female fish is needed, it is only necessary to remove the female fish when it has a fetal point (the female fish must have a fetal point earlier).

7. Production of precursors?

1 The abdomen of the female fish expands greatly, forming a square at the fetal point.

2 began to pull black stool, and the defecation was rough.

I don't like eating very much.

Always stand by quietly and drive away other fish.

Obviously, the barrel door is a little protruding.

6 The anal fin will contract and the tail will be raised from time to time.

8. The peacock fish gave birth

If the mother fish is suddenly disturbed by the outside world or the environment changes sharply before production, it may cause dystocia.

There is an artificial way to promote growth, that is, put in a heating rod to slowly raise the water temperature, then take out the heating rod and let it cool naturally, and so on. You can also replace the mother fish in childbirth with brand-new water, of course, after a gentle water distribution process, which will not only help to urge the mother fish to produce, but also avoid the mother fish from getting sick and give the newborn fish a clean environment. I think many people have the experience of suddenly giving birth to female fish after changing water or taking medicine, and it should be the same.

Whether it is necessary to have children is another topic. Some people are trying to grasp the time of collecting larvae, while others are afraid that the mother fish will have a difficult birth. However, in the general environment, the probability of dystocia is not high, but the pollution, urgency and even injury caused by improper use of the litter box may lead to the death of the mother fish, and ignoring the postpartum mother fish environment is also one of the reasons.

9. Postpartum care?

Change water after production. It will be better to reduce external interference and isolate female fish. Larvae can eat within a few hours after birth. The female fish has the ability to store the sperm of the male fish, and it is not a problem to reproduce several births without mating with the male fish.

10. How to choose fish?

A: In the choice of male fish, the male fish with large tail fin angle, eye-catching color and appearance, strong and symmetrical body, fat tail handle and full of vitality is the best choice.

In female fish, the most important thing is that the shape, color and appearance of caudal fin can show the characteristics of its species. In the best case, the female fish that has given birth to young fish is the most ideal fish, because its abdomen is very thick and dark.

3. Problems in the digestive system of guppy:

1. What are these white things?

A: It's enteritis. It's an obvious feature to treat it quickly, or the fish will be gone. The fish will stop eating and be fine in two weeks.

Four. Problems of breeding environment of guppy;

1. What should be the water temperature of the peacock?

A: The temperature tolerance range of guppy is about 20℃ ~ 32℃, and the most suitable temperature should be about 25℃ ~ 26℃.

2. What is the suitable growth environment for guppies?

A: Green algae water, keeping guppies in winter, and bringing big fish in winter is more beautiful.

3. Causes of fish diseases:

Improper water quality and temperature: fish have a certain adaptation range to the physical and chemical properties of water. If there are too many fish in the unit water, the ecological environment is very bad, which is beyond the scope of adaptation, and you may get sick. If the water is not changed in time, the fish will have too much excreta and secretions, carbon dioxide and ammonia gas will increase, microorganisms will breed, and cyanobacteria phytoplankton will grow too much, which will worsen the water quality, reduce dissolved oxygen and make the fish sick. The water temperature changes suddenly and the temperature difference exceeds 5℃; If the water temperature exceeds the upper or lower limit of the adaptation range, the water temperature will change in a short time, or the water temperature will be low for a long time, which will make the fish sick. If the water temperature is too high or too low, which greatly exceeds its adaptive temperature, the fish will die of heat or freeze to death immediately.

Improper feeding: ornamental fish rely entirely on artificial feeding. If the nutrients in the feed are insufficient, such as long-term feeding with dry feed, lack of animal bait, lack of protein, vitamins and trace elements, or inability to quantify regularly and uneven hunger, the fish will be malnourished and sickly. There is also the mildew and deterioration of the compound feed, and the fish will be poisoned and cause disease.

Inadvertent operation: in the process of changing water, cultivating tanks and fishing fish. Rough operation, careless injury to the fish, broken fins, or fish fell to the ground and injured parts are easy to be infected.

In addition, algae-attached fish are often scratched and their snouts are easily infected.

Pathogens brought in from the outside: There are many ways for external pathogens to be brought into fish culture containers, such as bait and aquatic plants. The tools used by sick fish are used for uninfected fish, and the newly purchased fish are put into the original fish group without isolation observation.

Verb (abbreviation for verb) Other questions:

What problems should be paid attention to in seed selection?

1. The male fish that grows very fast cannot be used because of its big body and small tail.

2. The shorter the female fish's body (from the front of dorsal fin to the end of ventral fin), the better.

3. The back shape of the mother fish should not be completely flat, and it should not be taken if it is slightly inclined.

4. The shape of the female fish's tail fin, which is an inverted triangle from top to bottom, depends on the female fish.

Fish feed

1. Additional water-soluble vitamins or lecithin can be added.

2. Male fish should be supplemented with vitamin E.

3. Small fish need protein, and change water frequently.

4. Grasp the winter, the color is big and the fish is solid.

6. Newborn guppy:

The water temperature is controlled at about 25℃. Small fish generally like old water. As long as it's not too cloudy, don't change it too often. Newborn fish should eat 2 ~ 3 times, preferably within 20 minutes each time.

When changing water, pay attention to the temperature change shall not exceed plus or minus 2 degrees.

The little fish is weak, so be careful not to make it sick. If you are sick, you should be treated immediately, and it is best to use specific drugs.

Seven. Aquatic plants:

How to disinfect?

Answer: 1. Disinfection of tap water. Tap water contains chlorine, which can kill pathogens attached to aquatic plants, but it cannot kill pathogens with strong resistance.

2. Salt disinfection. Add100-120g salt to each liter of water to make a salt solution, soak the aquatic plants for 15 seconds and take them out.

3. Copper sulfate disinfection. Put 10- 15g copper sulfate into every liter of water, soak the aquatic plants for 10min, take them out and rinse them with tap water at the same temperature. The advantages are that copper sulfate has strong bactericidal power, the disinfection time does not need to be accurate, but the cost is high.

4. Potassium permanganate disinfection. Add 5- 10g potassium permanganate to every liter of water, soak the aquatic plants for 5 minutes, and then take them out and wash them. This method has strong bactericidal power and can kill most pathogens.

5. Methyl blue disinfection. Dissolve 2 grams of methyl blue in 5 liters of water, soak aquatic plants in it for 10 minute, take it out and rinse it with tap water at the same temperature.
