Black-shelled shrimp is a generic term for hundreds of species of shrimp from the Atyoidae family produced in China, such as neocaridina denticulate, caridina curvifrons, Zhejiang rice shrimp (Caridina zhejiangensis), etc., and is not the Chinese official name of a species.
One. Why did the black-shelled shrimp I just bought come back and die a large piece?
1. Water quality problems
The author has seen a related problem sticker, the new tank urgently put shrimp, the water body is white, the water quality is not good at all, the nitrification system has not been established, the shrimp is completely a tank shrimp, not dead to be strange...
2. The shrimp itself carries diseases
Black shell shrimp is very resistant, but there are also many parasites that have a very strong pathogenic and lethality, and the black shell shrimp has just been bought back with a relatively thick brine to effectively reduce the corresponding loss, such as anchor worms.
3. Dissolved oxygen is not enough
The requirements of black shell shrimp for water dissolved oxygen are higher than those of ornamental fish, and it is generally necessary to keep the dissolved oxygen amount of water not less than 5ppm. In the summer heat, you can change more water to replenish oxygen, or add oxygen equipment to the aquarium.
4. Abuse of fertilizer
The black shell shrimp acts as a "cleaner" in the aquatic weed tank, and the various trace elements in aquatic grass farming are a kind of harm to the black shell shrimp. Because the waters in the native environment of the black shell shrimp are relatively poor in nutrients, and the trace elements in the aquatic fertilizer contain heavy metal components, the black shell shrimp will have a poisoning reaction.
5. Large carnivorous fish
I won't dwell on this...
Two. What are the specific conditions required for raising black-shelled shrimp
1. Water quality conditions
The viability of black shell shrimp is strong, the requirements for water quality are not high, the water temperature that is most suitable for the growth of black shell shrimp is 23 ~ 28 ° C, and the water pH value (pH value) is 6.0 ~ 7.5.
2. The water temperature should not be too high
Black shell shrimp is similar to crystal shrimp, suitable for growth of water temperature is 23 ~ 28 ° C, the highest can not exceed 30 ° C, the temperature is too high, microorganisms will be due to the reduction of oxygen content in the water and a large number of reproduction, resulting in water corruption.
3. Dissolved oxygen must be sufficient
4. Dodge
Black-shelled shrimp like to use densely planted aquatic grasses and stone crevices as their shelter. During the growth process of black shell shrimp, the growth process must be completed by molting. The black shell shrimp after molting is very fragile, so it is very important for the black shell shrimp to have a place to hide.
5. Feed
The cooked spinach leaves are quite good, and you can usually add meals.
I wish you a large amount of black shell shrimp and a prosperous shrimp.
