In terms of environmental water quality, the requirements of ordinary bee shrimp on water quality are not very high, but crystal shrimp is very sensitive. They need clean water, ammonia must not exist, and ammonia is often one of the main causes of their death. The survival conditions are PH 5.0~8.0, KH 1~6, water temperature 15~28, and the breeding conditions are PH 6.2~6.8, KH 1~2 and water temperature 24~26. When the water temperature is 25℃, it is the best temperature for hatching eggs. At high temperature, the life of shrimp will be shortened, because every time the temperature drops by one degree, the dissolved oxygen in water will increase. In other words, raising crystal shrimp at low temperature helps to prolong life. If the PH value is higher than 7.5, it will also cause immediate danger, which should also be noted. If crystal shrimp is found floating everywhere, it will be shocked by residual chlorine and pH oscillation or in poor health, and it will die after several hours to days! Therefore, be especially careful when changing water! If the crystal shrimp is found to be pale, it means that the water quality is getting worse! At this time, it is necessary to pump the bottom sand, remove the organic matter and feces from the bottom bed, and then change to 1/3 clean water! Under the condition of weak acid and soft water, crystal shrimp hulls frequently, grows fast and has a thin color; Under the condition of weak acid and hard water, crystal shrimp is not easy to shell, grows slowly and has a strong color. As for bait, you can feed crystal shrimp special feed, frozen red worm (which is not recommended because of the risk of carrying bacteria), kelp (kelp) or cooked seaweed. Cabbage is one of the favorite foods of crystal shrimp. Feed 1~2 times in about three days. If you don't eat it, it means the water quality has changed. Change the water quickly! Water plants and heavy trees are tied to Mu Si and put in shrimp tanks to help young shrimps avoid attacks! In addition, the fishy smell of shelled shrimps is easily attacked by peers, so it is necessary to plant aquatic plants densely and put in a proper amount of heavy wood! Mixed culture of fish and shrimp is basically in nature, shrimp is the bait of fish, and it is natural that shrimp hates fish. If there is no fish in the shrimp tank, the young shrimp will not have to worry about being eaten, and the shelled shrimp will not be attacked. Therefore, it is safest to raise shrimp alone in the shrimp tank! But because there is no fish, it will lead to the breeding of other creatures, such as worms, corals, snails, algae and so on! After a long time, it will cause a huge number and affect the appearance. Removing one by one is also very troublesome and painful, so we have to use fish to restrain it! When choosing fish species, eliminating pests is a great test. Fierce fish can naturally remove pests effectively and attack shrimps relatively! Therefore, it is necessary to choose fish species that are not interested in shrimp, and will not eat the artificial feed left by shrimp, because it is impossible to eat other creatures after eating the feed. In other words, choose the fish with small mouth, gentle temperament and no territory. (put fish in to drive away pests, only in adult shrimp tanks! But the general breeding shrimp tank is not suitable! But apart from pests, it would be better to completely eliminate fish, such as peacocks and seedlings of red swords.
