Excuse me, why can't crayfish be kept in plastic pots?

You bought a blue oyster and put it in a plastic basin, but there must be no filtration system in the plastic basin. It would be better if we could add a culture system.

If you don't have any equipment, you'd better change the water tank every day. Water should be dried one or two days in advance, and it is best not to use tap water directly. And whether the plastic basin is deep enough and whether the crayfish have the habit of fleeing. In addition, shrimp is afraid of heat and cold. The best ordinary small fish tank to buy 10 yuan. Shrimp is omnivorous and basically eats everything, so it is easier to raise.
