Guppy is a fish species with very high fishing value. It has rich and varied body colors and beautiful appearance. Many people will consider using guppy when raising ginseng at home. However, guppy is a species with very high growth ability. It is a strong species, so when raising guppies, you must pay attention to the growth of guppies. Below, the editor of Boqi.com will take a look at what we need to pay attention to.
Small guppies
一, Growth cycle of guppy
Guppy is an ovoviviparous fish. It has strong growth ability and early sexual maturity. The young fish will enter the mature period after being raised for 3-4 months and can grow offspring. The sooner or later sexual maturity is closely related to the water temperature and feeding conditions.
The growth cycle of guppies depends on the environment. It can grow about once a month, and the output of one litter is about 15 to 100 small fish, and the small fish can be cultured for 3 to 5 months. After that, it has the ability to reproduce and can give birth to the next generation.
Guppies give birth once a month. Depending on the size of the female, they can often give birth to 10-80 larvae. The number of larvae produced in a year is quite large, so it is known as the "million fish". When growing, attention should be paid to not leaving the same nest for more than three generations, lest the successive growth of direct relatives will lead to species degeneration, causing the offspring fish to become smaller and smaller and the tail fins to become shorter. It is best to introduce fish of the same species and carry out hybridization with distant relatives in order to prevent the species from degenerating and achieve the purpose of improving the species. However, the life span of guppies is very short, generally only 2-3 years.
2. Growth temperature of guppies
When guppies grow, they need to use a larger aquarium, and the water temperature is maintained at 26 degrees Celsius. The pH is 6.8-7.4. At the same time, some aquatic plants should be planted, and then the breeding fish should be controlled at a ratio of 1 male to 4 females. After the fish comes into estrus, the female fish's abdomen gradually swells and black fetal spots appear; the male fish has no time to chase the female fish at this time. When the male fish's connector is inserted into the female fish's cloaca, the sperm is removed and internal fertilization is carried out. When the female's fetal spots become large and black, and her anus exceeds her anus, she can be fished into another aquarium to wait for delivery. After the female fish gives birth, she should be fished out immediately to avoid eating the larvae. Or, plastic sheets should be used to form a funnel-shaped partition wall, occupy the water, and place the larvae female fish in the funnel, so that the larvae will fall from the bottom of the funnel into the water outside the funnel, and the female fish will not be able to eat the larvae.
3. Guppy growth signs
Female peacock fishWill be produced with the following characteristics:
1. The body shape is square. When viewed from the side, the belly of a female fish looks like a rectangle, which is relative to the normal shape of the belly, but not strictly square.
2. The color of fetal spots is relatively dark. Generally, the fetal spots of outstanding fish in the wild are black, and there are also other colors. It is better to judge from the area of the fetal spots. Generally, the fetal spots of female fish to be produced are relatively large.
3. Protruding anus. If the anus protrudes, it means that the female fish will give birth soon, and she must prepare to deliver the baby.
4. Behavioral display. Female fish that are about to consume or are in the process of consumption will generally appear in two states. Some will jump up and down, and some will hide quietly in a corner.
IV. Matters needing attention in the growth of guppies
1. Before the young fish are born, the pH must be between 4.5 and 5.5, and after they are born, the pH must be at 5.5 ~6.5.
2. From the time after spawning until the young fish are moved away, the parent fish are not fed.
3. The broodstock can only provide milk for 6 to 7 days, otherwise it will cause overwork and affect the body.
4. On the 13th to 14th day after birth, the young fish must be fished out and raised in a large tank for cultivation.
5. The broodstock will rest for 3 to 4 days after the young fish move away, and then they can consume the next batch of small fish.
6. The broodstock will continue to consume in this way for about 11 times.
Out of 7 and 11 times, there was no victory in the first three times.
8. Female fish can consume a total of 22 to 25 times in their lifetime, but after consuming 11 times, they have to rest for a long time before starting the second phase of ovulation.
