Yes, it is a small mussel, just put it in fresh water. If you eat it, it has an earthy odor, we recommend that you put it in the water for a while to spit out the dirt, then isolate it, take the meat, chop it up, add it to the egg and scramble it, and remember to put vinegar in it!
Look at the fish food you put in the bucket, mussels grow in the mud, eat humus and sand.
