Ar-1430 DWARF HERMIT CRAB, Pagurus longicarpus

A small, active hermit that starts scurrying about the minute it is placed in your aquarium. Highly aggressive among themselves, they afford the aquarist with many fascinating hours as they bluff, fight and swap shells. Some specimens often jump out of their shells when handled, exposing their soft abdomens. Experiments have shown that Pagurus can discriminate between yellow and blue painted shells. Size of shell: 2 cm.
