Water maintenance: Take tap water, at least to cover the mussels, and spread a layer of sand on the bottom of the tank for the mussels to inhabit. It can be mixed with many fish to ensure that there is no lack of oxygen in the water.

Temperature: Place in a cool place, remember not to expose it to the sun. Be sure to avoid direct sunlight in summer, otherwise it will die easily.

Feeding: River mussels have a wide range of food habits, mainly phytoplankton in fresh water such as diatoms and euglena, zooplankton such as rotifers and flagellates, and decayed debris of other aquatic plants and crustaceans. It can also be used as food.

Extended information:

The food of clams is mainly monocystic algae, protozoa and organic debris, such as rotifers, flagellates, green eyeworms, green algae, and Algae, Navicula, dinoflagellates, Tetragonal algae, spindle diatoms, rod star algae, crustacean debris and plant leaves, etc. Easily digested are mainly diatoms. Mussels cannot actively chase food. They rely on the opening and closing of the clam shell and the swinging of cilia on the inner side of the mantle and gill cilia to cause water flow, and food enters the mussel body with the water.

Food enters the mantle cavity with water, and the particles move upward along the gill filaments to the base of the gills, and then move forward to the labial valve. After being selected by the labial valve, small particles enter the mouth, and large particles pass through the edge of the inner gills. Move backwards, at the intersection of the two cheeks, enter the mantle mark to the rear end, and the two shells are suddenly closed and discharged from the body. According to some statistics, up to 40 liters of water flow into the clam body every day.
