Buying Guide: Key Purchase Considerations
To choose the best shells for stuffing and enrichment, consider shell size ranges relative to your crabs’ current and expected growth. Natural shells are often preferable for safety and scent familiarity, while a mix of sizes helps crabs transition smoothly during molts and growth spurts. Look for shells with smooth interiors and no sharp edges to prevent injury. If you keep multiple crabs, a varied assortment reduces competition and encourages healthy shell selection. Finally, consider maintenance: natural shells don’t require coatings or paints, which can introduce odors or residues that crabs may avoid.
