These terrestrial crabs spend most of their lives on land but require access to both freshwater and saltwater. Their vibrant coloration resembles Halloween-themed colors, giving them their popular common name.
Personality & Qualities
Halloween Crabs are active, curious, and entertaining to observe. They spend much of their time digging burrows, exploring their habitat, and foraging for food. While they can recognize feeding routines, they are not pets that typically enjoy handling.
Daily Care
Provide fresh food and clean water daily. Maintain proper humidity and temperature levels and ensure both freshwater and marine saltwater dishes remain available. Spot-clean the enclosure regularly while preserving burrow structures whenever possible.

Halloween Crabs require a tropical-style enclosure. Recommended setup includes: Minimum 20-gallon enclosure for one crab Larger enclosures for groups 6–10 inches of moist substrate for burrowing Freshwater pool Marine saltwater pool Cork bark hides Branches and climbing opportunities Leaf litter Secure lid Deep substrate is essential because crabs burrow during molting.
