Buying Guide: Key Factors To Consider

- Shell material and finish: Natural, unpainted shells reduce risk of chemical exposure. Cleanliness and odor-free shells support crab health.
- Size range and variability: A set with multiple size options helps crabs select during shell swap and grow over time.
- Maintenance: Natural shells may accumulate algae or debris. Regularly check and rinse as needed to maintain a safe habitat.
- Display and habitat goals: For decor, larger stand-out shells can serve as focal points; for curated habitats, prioritize size variety and fit.
