Coenobita Brevimanus is one of the largest species of hermit crab in the trade, boasting a has a robust purple exoskeleton, but it’s their eyes that really catch your attention—perched on long stalks, they move about curiously, surveying their surroundings. These hermit crabs are not ones to just sit around. They love to explore their surroundings, whether it’s climbing decor, digging through substrate, or interacting with other tankmates. Despite their small size, Coenobita Brevimanus are fearsome little critters, especially when they raise their larger claw (from which they get their name, “Brevimanus” meaning “short hand”) as if they’re the guardians of their tiny territory. These are nocturnal animals that come to life at night, exploring and adventuring around their habitats. These hermit crabs are highly social animals and must be kept in groups of at least 3 members to ensure they do not become depressed. 3 or more is better on the off chance one perishes.
