As an ornamental aquatic creature, crystal shrimp is now hot, and more and more people are raising crystal shrimp, but the high mortality rate of crystal shrimp has discouraged many fans.

There are many reasons for the death of crystal shrimp, but it is nothing more than the following conditions:

1. Cannibalism

Crystal shrimp often kill each other, especially in breeding When the density is too high, the object being attacked is often an individual who has just shed its shell. Individuals who have just shed their shells attract similar attacks due to their slightly fishy smell.

Prevention method: densely plant aquatic plants to allow shrimps to have a secret place to avoid attacks from other shrimps.

2. Freeze to death

Water temperature is too low will affect the activity of crystal shrimp, the body temperature limit of shrimp is 10 degrees Celsius, lower than 10 degrees Celsius will easily lead to shrimp death.

Prevention method: Use a thermostat to automatically control the temperature in the fish tank, which can keep the temperature constant for a long time.

3. Planarian attacks

Planarians are mainly parasitic on the skin of shrimps, causing severe damage to the respiratory function of the shrimps, causing the gill tissue to proliferate and secrete a large amount of mucus, which makes dirt in the water It is easy to adhere to the gill filaments, so when observed with the naked eye, the shrimp will have difficulty breathing in severe cases, roaming on the water surface in anoxic state, and die soon. The infection of planarian disease is closely related to the health of the crystal shrimp. If the crystal shrimp is healthy, the infection rate is low. Once the temperature drops, the worms will naturally fall off the crystal shrimp, and the crystal shrimp will quickly recover health. On the contrary, the mortality rate has increased greatly, especially some crystal shrimps, which are usually thin and malnourished, are more likely to cause a large number of deaths.

Prevention method: To prevent planariasis, you can hang copper sulfate sustained-release tablets in the cage, and add multivitamins to the bait.Enhance the resistance of crystal shrimp. When there is a large amount of parasites, you can use "Protozoa" or "Yujing high copper" (both copper sulfate and ferrous sulfate mixture) in the morning and evening when feeding bait with high concentration splashing medicated bath treatment.

4. Dry dead due to tank jump

If this happens, it is recommended that the water level of the tank should not be set too full, preferably more than six centimeters from the edge of the tank.

5. Death due to egg holding

is generally caused by the deterioration of water quality. This situation may also occur if the shrimp is not fully shelled.

Prevention method: You can use porcelain plates to raise shrimps. If you are using a fish tank, you must add a filter to filter out the dirt in the fish tank, keep the water clean, and increase the amount of oxygen to purify the water.

6. Death in shock

This situation will occur, and it is usually caused by water quality. Unqualified water temperature and PH value will cause the shrimp to die abnormally.

Prevention method: To breed high-quality crystal shrimp, the most important thing is water quality. Crystal shrimp is different from general ornamental fish, it is very sensitive to water quality. In terms of water quality selection, the most important thing is to reduce the "killers" in the water-such as controlling the content of harmful substances like ammonia, which is a prerequisite for making crystal shrimp high-quality. Because the crystal shrimp has higher water quality requirements, the pH value of the water in the tank should be controlled between 5-8, and the KH value (the relative hardness of the water) should be between 16. Generally, the pH value is 6.2—6.8, and the KH value is 1-2. However, it should be noted that if the pH is higher than 7.5, it will also cause danger. Dechlorination and pH vibration can cause shock or poor health of the crystal shrimp, which may float everywhere. In severe cases, the crystal shrimp will die within hours or days. If you find that the color of the crystal shrimp has faded, it is a sign that the water quality has begun to deteriorate.

7. Individuals with poor health

It is very difficult to determine the health of shrimps.The so-called bad individuals can be distinguished from the turbid body color and the slower tail-foot swing. If the shrimp died due to physical problems, there is no better way except to increase the physical fitness of the mother.

Prevention method: The physique of shrimp can be improved through diet. Shrimp is omnivorous and is basically "vegetarian": grains, flakes, bloodworms, brine shrimp, moss, algae, aquatic plants, minerals in mud, special food for freshwater shrimp, organic vegetables, etc. are all edible , But don't eat dead fish. Bocai is one of the most favorite foods for crystal shrimp, and other baits such as special feed for crystal shrimp, frozen red worms (there is a risk of carrying bacteria, not recommended), kelp (kelp) or cooked bocca. It is fed 1-2 times a week. If he refuses to eat, it means that the water quality has changed and he should change the water quickly. Other studies have pointed out that in addition to the vegetarian shrimp, the minerals in the mud are the second, so mud at the bottom of the tank would be better. The main food of juvenile shrimp is green algae, moss and tiny organisms in the water.

8. Death due to illness

If the shrimp unfortunately died of illness, in order to prevent other shrimp from being infected by bacteria, it is best to remove the dead shrimp from the tank immediately.

9. Unexplained

This is the most dangerous signal. Shrimp becomes sluggish in movement, then its body color becomes transparent and cloudy, and it will die soon after.
