I’m looking for a new pet?

I would love to adopt a small pet to care for that lives for a MAXIMUM of 5 years. (Preferably less…) I am moving into a college dorm soon. So I would love a companion that takes less work to care for. Something that doesn’t have a tendency to bite or be hostile towards me… I was thinking of a turtle, but they live 15+ years. Any ideas? (Fish are alright, but what others pets are there?
