It is best to feed some grass foods frequently, such as Sophora alopecuroides and Elodea.
There are two ways to feed, vegetarian and meat. The so-called vegetarian diet means eating hormones, which is a complex compound fertilizer. I remember oxytocin. . . . . Then eat meat, which is very easy. As long as it is the meat of dead things, only rotten crabs can eat it.
I suggest that the water should not be too deep, and then put an allegro on the water surface so that it can climb up. It's better to put some sand or something under the water. As for food, of course, there are some small aquatic plants, and the most important thing is small fish. Catch crabs when I was a child. The bait is dead fish and tastes delicious.
The water can't be too deep. You'd better stick your eyes out of the water. Get a small platform if you can. If it is a hermit crab, you must get a platform. If possible, feed live red nematodes or egg yolk. (pay attention to feeding. Eat it in half an hour. If you can't eat it, it will make the water dirty. ) Pay attention to supplement foods rich in calcium after shelling.

Eriocheir sinensis is selective in feeding on aquatic plants. In the annual breeding period, POTAMOGETON crispus (spring) and hydrilla verticillata (summer and autumn) are two favorite food species in different seasons, Ceratophyllum crispus, yellow silk grass and Sophora alopecuroides are alternative foods, and POTAMOGETON malayi and Myriophyllum japonicum are forced species. Of course, this ranking is not a fixed model, and the choice of aquatic plants by river crabs is related to the population structure of aquatic plants and their respective biomass
The food composition of Eriocheir sinensis is diverse, and the experiment proves that the intake of various foods by Eriocheir sinensis is obviously higher than that of a single food.
Besides collecting various grass species, special attention should be paid to the transplantation of POTAMOGETON crispus in pond culture. Potamogeton crispus, commonly known as "wheat yellow grass", is a favorite variety of Eriocheir sinensis in early spring.
