Generally speaking, crystal shrimps are fed every 3 days or so. Because they can feed on algae and microorganisms in the water, there will be no shortage of food in the tank with soil and aquatic plants. Don't feed them often, let alone every day. Otherwise, the food they can't eat will remain in the water, pollute the water quality, and then affect the normal growth of shrimp.
If you are raising newly born shrimp, you can sprinkle some microbial powder into the water tank to provide them with food. If the shrimp are grown, they can be fed with cooked spinach, which they like very much. In addition, you can also feed some kelp, algae shrimp food or red worms. However, if you want to feed red worms, you should disinfect them in advance to prevent them from containing parasitic eggs or pathogens, leading to crystal shrimp illness.
If it is just moved into the new tank of crystal shrimp, do not eat may be because they have not yet adapted to the new environment. After a while, they will feed on their own. If the crystal shrimp cultured for a period of time does not eat, and some shrimp die, then it may be a water quality problem. At this time, water should be changed in time and maintained slowly.
