Hermit Crab Behavior tools: what they help with
These tools help you read your hermit crab: temperament quizzes, compatibility checkers for multi-pet homes and guides to what common behaviors usually mean. Most behavior problems start as a mismatch between what a hermit crab needs and what it is getting. Spotting that early is far easier than fixing a habit later.
What to know about behavior and temperament for hermit crabs
Hermit crabs typically live 10 to 20 years. Hermit crabs are social colony animals needing at least 15cm of damp sand to bury and molt in, plus both fresh and salt water dishes and many spare shells. Most deaths trace back to too-shallow substrate.
