1. If it is a fish tank with a large number of aquatic plants, it can be directly used to raise mussels because there is already a bottom sand layer for planting aquatic plants;

2. If it's naked tank culture, it's necessary to lay a layer of sediment on the bottom of the tank for mussels to inhabit.

Mussels are widely distributed in rivers, lakes, reservoirs, ponds, rice fields and other water bodies, and usually live in sediments at the bottom of the water. In the natural state, only the back end of mussel body is exposed from the sediment, and the inlet and outlet pipes are often opened to maintain the uninterrupted flow of water in the body and normal life activities. Mytilus usually lives in shallow water in blocks or strips, likes flowing and clean fat water, and is generally suitable for living in neutral or weakly acidic or weakly alkaline water.
