Hermit Crab Health tools: what they help with
These tools support everyday health care for a hermit crab: body condition scoring, vaccination and check-up schedules, dental care plans and symptom checkers. Hermit crabs often hide illness well. Regular, structured checks make it easier to notice small changes before they turn into an emergency.
What to know about health and preventive care for hermit crabs
The problems seen most often in hermit crabs are failed molt from shallow substrate, shell fights from too few spare shells, dehydration without salt water and stress from isolation. Over a 10-20 year life, catching these early makes a real difference.

A practical tip
Write down the date and result each time you use a health tool. A trend over weeks tells a vet far more than a single reading.
