2. Mytilus is a filter-feeding mollusk, which lives by filtering the organic matter in the sludge in the water. If you want to feed mussels artificially, you can't turn on the filter pump, but you can pump oxygen.
3. Mytilus is an aquatic organism with high oxygen content. Mussels in fish tanks can really filter water and purify water. It is not worth the loss to purify water by mussels alone. If mussels are used to breed partridges, they can be kept alone in a water tank, and the water depth should not exceed 20 cm, which is easy to lack oxygen. Soymilk or green water, once every three to five days.
