Polka Dot Hermit Crab

Care Summary

The Polka Dot Hermit Crab is a small, active scavenger recognizable by its bold spotted coloration and energetic personality in the display tank. It does well in reef and fish-only systems but will evict snails from their shells, so always keep a supply of empty shells in various sizes to reduce aggression toward tankmates. Shell fights are its primary compatibility risk, and overcrowding without extra shells leads to losses among your snail cleanup crew. It is omnivorous and forages constantly for detritus, algae, and uneaten food, requiring no target feeding in a healthy, well-fed reef.
