It should be possible, but according to the genetic law, the probability of the offspring appearing white crow is very small, because it is a recessive gene, but it is not excluded that the appearance of shrimp with mixed colors of both parents, such as blue and orange unevenness in the body.

When it grows to 3 months, it is the age of crayfish reproduction, once or twice a year, at this time, we must ensure that the space in the tank is large enough, the water quality, temperature, etc. are in the best state, and after successful mating, you can appropriately add some high egg pants jujube white food;
After a period of time, you will find that the female shrimp is hiding, and even the rock shed will block the hole, at this time the shrimp has successfully held the eggs, at this time do not alarm it, otherwise it is easy to kick the eggs, if there are conditions, it is best to isolate them.
After the mother shrimp holds the eggs, it must ensure that there is enough mosse in the tank, which is to block the light, but also to provide sufficient food for the mother shrimp, after holding the eggs, the water temperature can be slowly raised by 1 to 2 degrees, but the temperature should not be too high, otherwise it will cause hypoxia necrosis.

These three are all ordinary crayfish, yellow is better than white, and I have never raised blue.
Body length: 10cm-15cm in the wild, artificially domesticated 6cm-10cm Lifespan: 2-5 years (mainly according to the environment, the general survival life in the wild is longer) Body color:
Brown, brown-red, orange, olive-green and gray-blue food: omnivorous, aquatic weeds, bloodworms, earthworms and small fish can be temperature: 5-26 degrees Optimal feeding temperature 20-23 degrees Total hardness:
5°dgh—20°dgh
pH: Feeding difficulty: medium difficulty.
Difficulty of breeding: Not easy to reproduce.
Feeding water temperature to maintain 23 below the low temperature of the feeding environment, keep the water quality clean, the amount of water can not be too high, can be used to raise the water motor to create the effect of water flow, in order to maintain the best dissolved oxygen and water quality conditions, it is recommended that 40 cm tank can be stocked 2-4 (5 cm specifications), feeding tank needs to be set up neutral bottom sand, sunken wood, PVC pipe, clay pots, etc., to prevent mutual attack, this shrimp species, for the night habit, often foraging activities at night, so need to be fed after 9 o'clock in the evening, the next morning can be eaten, Don't worry about polluting the water. In addition, in feeding, you should pay attention to the capping, it will run away, I once forgot to cover when feeding, resulting in a lot of loss of escape records. This kind of shrimp generally does not get sick, but the demand for dissolved oxygen in the water is high, and it is best to change the water regularly to maintain the oxygen content and cleanliness of the water.
Plant-like food: prefer aquatic plants and molluscs such as snails, earthworms, etc., and also eat cooked spinach or other vegetables. Basically, though, they will eat all the organic matter they find.
It takes about 19 days to reproduce at a water temperature of 22 degrees. At a water temperature of 24-26 degrees, the fertilized eggs incubate for 14-15 days to break the membrane and become larvae, and at 20-22 degrees Celsius, the fertilized eggs take 20-25 days to hatch. If the water temperature is too low, it can take months for the fertilized eggs to hatch.
The newly hatched larvae are 5-6 mm long, nourished by the yolk, and molt and develop into second-stage larvae after a few days. The larvae of the second stage are about 6-7 mm long, the appendages are well developed, the frontal horn is curved between the eyes, and its shape is similar to that of an adult shrimp. The secondary larvae are attached to the mother's abdomen, can feed on microorganisms and plankton brought by the mother's respiratory current, and can stand after leaving the mother's body, but can only walk weakly, and can only swim back to the mother's abdomen for a short distance.
In the first and second larval stages, the female shrimp is disturbed at this time, causing the female shrimp and the larvae to be separated too far, and the larvae cannot return to the abdomen of the female shrimp, and the larvae will die. The larvae of the second stage molt and develop into adult shrimp after a few days, with a total length of about 9-10 mm. At this time, the larvae are still attached to the mother's abdomen, and the shape is almost exactly the same as that of the adult shrimp, and the larvae also have a great dependence on the mother and become a juvenile shrimp with the mother leaving the burrow and entering the open water.
Under the water temperature of 24-28 degrees, the development stage of freshwater shrimp larvae takes 12-15 days.

Upstairs copy the party, answer the question, or I'll come:
White crayfish, orange crayfish, blue crayfish, everyone is crayfish, there is no color better to raise, crayfish are gray and easy to raise, the temperature is 5-26 degrees, you can feed the kind of ordinary cherry blossom shrimp to eat the sinking piece of feed. Of course, crayfish eat a lot of things, aquatic plants, feed, bloodworms, small fish, small shrimp, green vegetables, etc., sometimes you eat meat at home, wash it, and then give it to eat! The fish tank is set casually, as long as you think it looks good, spread some bottom sand.
Black King Kong or something, and then you can get two ceramic cylinders, that's the basic situation!

1. When the body length of the crayfish is more than 8cm, the feeding time is more than half a year, and the tail can be mated.
Put the male crayfish into the female crayfish breeding tank, observe whether the female shrimp let the tail mate, from familiarity to action is also very fast, if there is no mating during the day, to be safe, separate them before you go to sleep, and close the tank again the next day. Normally, if a pair of shrimp mates, they will not attack each other very affectionately. It should be noted that if there are signs of shelling of shrimp during the closing of the tank, then the tank must be divided, and when the shrimp is shelled for 5-7 days, the shell is calcified and hard, and the tank is closed again.
2. The seminal vesicles are full several times, and the female shrimp does not let the male shrimp mate, and there is not much to eat, so you can take the male shrimp out at this time and give the female shrimp a quiet environment to wait for the eggs.
3. After a period of cycle, the female shrimp basically does not eat, and is turning the bottom sand, creating a sand pit or hiding in the jar and not coming out, and she is about to hold the egg.
4. During the period when the female shrimp holds eggs, there is no need to feed animal feed, and some aquatic plants are put in the tank, and it will occasionally eat some. Precautions: Be sure not to frighten it, let alone use a net to catch it, so it will basically kick the eggs.
Try not to change the water during the egg holding, and add water with a slow flow of water to avoid obvious changes in pH and temperature differences.
5. The egg-holding cycle is 25-28 days, the juvenile shrimp has been formed, and gradually will walk around the female shrimp's abdomen, but it is basically around the female shrimp.
6. After the female shrimp is shaken, she has to shed her shell several times before she can enter the next mating and reproduction cycle.

<>1. The eating habits of the shrimp are more mixed, and they can eat fresh and tender grass roots, humus, aquatic plankton and artificial compound feed! You can also rely on fertilizing water and regularly sinking some fresh grass into the water or planting some aquatic plants! Although it is resistant to low oxygen, when the dissolved oxygen in the water reaches more than 4 milliliters, it is more conducive to increasing the growth rate.
2. The suitable water temperature for blue shrimp is 4 32, the suitable water temperature for growth is 15 30, the optimal water temperature for growth is 20 28, and the lowest temperature that can be tolerated in the short term is 1 4. When the dissolved oxygen level reaches more than 2 milligrams, it can grow normally. The maximum individual can reach 500 grams.
However, artificial aquariums are generally 75-200 grams.

Blue crow shrimp is blue devil shrimp, which eats fresh and tender grass roots, fengqing humus, aquatic plankton and artificial compound feed.
How to raise blue crayfish:
1. The size of the fish tank should be determined according to the number and volume of shrimp, and four adult shrimp can be raised in a one-meter fish tank;
2. The bottom sand should be made of black work, coral sand and volcanic rock, and the proportion of one state acacia can be one;
3. The pH value of the water should be controlled between 8 and 8, because the acidic water quality is not conducive to the molting and growth of shrimp, and will also make the formation of soft shells, which will bring harm to the normal life of shrimp;
4. The water temperature can be controlled between 10 and 32 degrees Celsius.

Blue shrimp is suitable for raising with anchovy, whitebait, jade tendon fish, anchovies and other medium-sized fish, if the fish is too large, it will eat the blue shrimp, if the size is too small, it is easy to be eaten by the blue shrimp, so the size of the fish is very important, when raising the blue shrimp and other fish, you need to feed the food on time to avoid the big fish from eating the blue shrimp due to hunger.
Blue crow has a certain aggressiveness, so what kind of fish is raised with blue crow, such as anchovy, whitebait, jade blind sedan tendon fish, anchovies and other medium-sized fish are raised together to avoid fighting with each other.
If the blue shrimp is large, it may eat other small fish, and the small size of the blue shrimp will be eaten by other large fish, so the blue shrimp should be kept with the right size fish.
No matter what fish the blue shrimp is raised with, the water needs to be changed regularly, the water quality needs to be kept clean, the water needs to be oxygenated in time, and the fish food and shrimp food should be fed regularly to avoid the situation of big fish eating blue shrimp.
In fact, the two foods you are talking about, crab and shrimp, are the two favorite dishes of most people, and because these two beautiful things have various practices, in order to show off the ** cheap, so they are very popular, so these two foods can be eaten together? In fact, you can try it together, uh, the doctor said that you can eat it together, because this is the same kind of product, crab and shrimp can be eaten together, but you must pay attention, be vigilant against gout, patients do not eat crabs and shrimp, and that's it, crabs and shrimp, don't cook them for too long, and the crabs will be fished out when they are cooked.
Jimmy shrimp, also known as Shangji shrimp, belongs to the rice shrimp category, which is different from the crystal shrimp species and can be polycultured. The reference map of ornamental shrimp polyculture is as follows.
Shrimp and walnut kernels, I think they can be eaten together, there is no problem, one is nuts, and the other is vegetables and seafood.
Vitamin C cannot be eaten with shrimp.
Cucumbers can also be eaten after eating shrimp, which does not have much impact on our health, so it is said that it can be eaten.
