Hermit crabs are a top choice for college students because they're quiet and low-maintenance. You don't need much for a hermit crab, either. Start with some containers of hermit crab food and a tank that allows your crab space to explore (5 gallons of space per two crabs is recommended). Add in some extra shells for your hermit to try on as it grows, and both you and your hermit will have the best college experience together!
