Can the clams bought today be eaten tomorrow? Do you want to raise it? How to raise it? I bought it alive. Can I eat it after I die?

Better raise it. Let it spit out sediment and the like, which is more hygienic and tastes good. If you want to eat it in a few days, I suggest you treat it like a hairy crab, buy it and put it in the refrigerator, put some water (there is usually a meat or vegetable freezer in the refrigerator) and keep it inside. It's so hot now, if you keep indoors, you'll die immediately. Dead seafood can't be eaten, especially in hot weather, which will soon go bad. I hope my answer can help you:)
