In the purple pincher vs Ecuadorian hermit crab matchup the purple pincher is the easier beginner pet. It tolerates a wider temperature and humidity range and is by far the more common species in U.S. pet stores.
The Ecuadorian is smaller and faster, and it needs steadier heat and moisture so it suits a keeper who already has crabbing experience.
