There is nothing special about keeping mussels in a fish tank. If there are fish tanks with a large number of aquatic plants and a bottom sand layer for planting aquatic plants, you can directly put them into mussels. It is necessary to lay a layer of sediment at the bottom of the bare tank for mussels to inhabit.

Mussels are generally suitable for living in neutral or weakly acidic and alkaline water, but different kinds of water have different requirements. Both ANODONTA dorsalis and ANODONTA rugosa can survive in pH 5~9. Hyriopsis cumingii often needs to live in water with pH7~8. The requirement for dissolved oxygen in mussels is not high, and the lower limit is about 3 mg/L. Mytilus has strong drought resistance. Generally, mussels buried in the soil will not die after half a month of drought, but they will die when exposed to the air, especially in the hot summer sun. ?

Mytilus has a wide range of feeding habits, mainly phytoplankton such as diatoms and gymnosperms in fresh water, zooplankton such as rotifers and flagellates, and other aquatic plants and crustaceans can also eat rotten debris.
