HI, This is not a hobby of mine! I just found a baby octopus in a seashell!What can I do to keep him alive? What should I do with him? I would love to keep him if it is possible to get a small saltwater tank. Should I take him to a pet store? Take him back to the beach? Or take the adventure and keep him? I just don't want him to die right now, so I need temporary care advice! Thanks!
