How did the black shell shrimp disappear after holding the eggs?

Black-shelled shrimpThe reason why the eggs disappear after holding them is that they need to concentrate on incubating the eggs, and of course they may die.

Black shell shrimp is a general name for hundreds of shrimp species of various spoon finger shrimp families produced in China, such as multi-toothed new rice shrimp, curved forehead rice shrimp, Zhejiang rice shrimp, etc., and is not the official Chinese name of a species.

Black shell shrimp is a very gentle shrimp that will not attack any fish in the tank, does not need to be fed, does not require high temperature (but try to avoid high temperatures), and is good for suppressing algae in the tank.

The flooding has a very large effect, so the black shell shrimp can be said to be a very good fish tank cleaner. But because of the excessively mild nature of the black-shelled shrimp, they also lack the ability to defend themselves.

Shrimp and juveniles in the molting stage are very susceptible to being injured or eaten by fish. Therefore, when raising fish in the tank, try to plant more aquatic plants or place facilities such as shrimp houses for black shell shrimp to hide. And be careful not to associate black-shelled shrimp with overly ferocious fish such as bettas.

Spiny loach, goby and other polycultures, in this case, even if you dodge more black shell shrimp, they will be eaten completely.

The optimal living temperature for the black shell shrimp is 10 30 , but it can survive in the extreme temperature of 5 35 and can even tolerate lower temperatures than 5, but the black shell shrimp will stop eating at such temperatures.

Low temperatures do not affect their survival, but it is not conducive to their reproduction, and even if there are hatched shrimp seedlings, it is not easy to survive below 10. With the increase of water density, the maximum limit temperature of black shell shrimp will gradually decrease.

How do protein worms die after hatching into black shellworms.

The eggs of the black-shelled shrimp lay on the swimming feet of their abdomen.

After a period of 18-25 days, the eggs hatch into juveniles. In order to ensure that they can hatch the shrimp safely, they will find a place that they think is more hidden after holding the eggs. The more common ones are in aquatic plants and in the crevices of stones.

After the shrimp hatch successfully, they will fall into the crevices of aquatic plants or stones. After 5-7 days, the shrimp can move freely.

How to raise black shell shrimp and small shrimp:

1. Water temperature: Black shell shrimp do not have high requirements for water temperature, and they can live in a water temperature between 5-35. However, newborn black-shelled shrimp are weak, and it is best for keepers to keep the water temperature between 24-28.

2. Water quality: The requirements for water quality are not very high, and the pollution of water quality is not serious. If the water is small, you can change the water every 1-2 weeks.

3. Feeding: Black shell shrimp like to eat some brown algae, filamentous algae and other foods, but they are just born, and the keeper can only feed them some chlorella powder, spirulina powder, etc. The amount and frequency of feeding should not be too high, so that indigestion can be avoided.

The shrimp did not take shape, and the shrimp eggs were kicked off.

As a small expert in algae removal, the black shell shrimp is almost an essential creature for aquatic weed tanks, and it takes about 20 days for the black shell shrimp to come out from the eggs.

Black shell shrimp can hold eggs all year round in a suitable environment, preferably at 26, the time of holding eggs of black shell shrimp will change with the temperature, such as the water temperature of black shell shrimp female shrimp holding eggs between 20-26, raw shrimp generally takes about 15 days, when the temperature has been hit to 26, it takes 13-14 days for black shell shrimp embryo development, and when the water temperature is 22-24, it takes 15-16 days.

After the black shell shrimp holds the eggs, the small shrimp will come down on their own when they are formed. Generally, in a water temperature of 26 degrees, the eggs of the black shell shrimp will hatch after 13 to 14 days. After the black shell shrimp hatches, pay attention to isolate the other fish in the fish tank to prevent the small shrimp from being eaten.

After holding the eggs, the black shell shrimp will keep the eggs on their bodies until the small shrimp come down on their own after they are formed. During this period, if the black shell shrimp kicks eggs, it may be a big change in water quality, and it is necessary to pay attention to adjusting the water quality.

The time for the production of eggs of black shell shrimp will vary with the water temperature, at a water temperature of 26 degrees, it takes 13 to 14 days for black shell shrimp to produce. When the water temperature is 22-24 degrees, the black shell shrimp takes 15-16 days to produce.

After the black shell shrimp hatch the baby shrimp, be careful not to let the water temperature in the tank change too much, otherwise the baby shrimp will not be easy to survive. If there are other fish in the tank, be careful to isolate them to prevent them from eating small shrimp.

The shrimp is not formed, and the shrimp eggs.

Kicked out. As a small expert in algae removal, the black shell shrimp is almost a necessary biological return in the aquatic weed tank, and it takes about 20 days for the black shell shrimp to come out from the eggs to the small answer shrimp.

Black shell shrimp can hold eggs all year round in a suitable environment, preferably at 26, the time of holding eggs of black shell shrimp will change with the temperature, such as the water temperature of black shell shrimp female shrimp holding eggs between 20-26, raw shrimp generally takes about 15 days, when the temperature has been hit to 26, it takes 13-14 days for black shell shrimp embryo development, and when the water temperature is 22-24, it takes 15-16 days.

Shrimp is received from the body.

Fine, not self-resembling the general fish bai

In vitro fertilization. Whether it is grass shrimp, Du node shrimp, zhi white shrimp, freshwater long dao arm shrimp, mountain shrimp, black shell shrimp, rose shrimp, crystal shrimp, flame shrimp, crayfish, lobster, cherry blossom shrimp are all in vivo fertilization, and no type of in vitro fertilization shrimp has been found.

Shrimp ovaries are shelled after maturation, and mate with male shrimp in about 3 to 6 hours.

After the completion of mating, the fertilized eggs will be discharged from the abdominal genital orifice within 24 hours, and gather in the abdomen to swim and hold the eggs, about 15 to 25 days to hatch the shrimp seedlings big-eyed larvae, if the water temperature is below 24 degrees Celsius, the egg-holding period will be very long, adjust the water temperature to 26-28 degrees 13-14 days can hatch.

Reproduction is in a completely dark environment, and you don't know how big the cylinder is? If you exclude the original shrimp 80 filtered, but the associated problem of damage. In fact, algae are not necessarily black-shelled shrimp.

。Grass shrimp as well, selling shrimp feed only bought a few places with a lot of money.
