There aren't a ton of easy pets to take care of in a dorm room. I know people who have snuck cats, rats, and snakes into their dorms, only to be scolded by the resident assistants or their roommate. If you're looking for super easy pets to take care of while away at college, this list can give you some good ideas!
Of all the easy pets to take care of in a dorm room, a fish has to be one of the easiest. Fish are fun to look at and generally require very little maintenance. Betas, guppies, and goldfish are all fish I have had while living in a dorm. They are especially easy because they don't require any special lights and can live in a regular fish bowl.
