Natural History: The Halloween Hermit Crab is normally found in sandy areas of coral reefs where it patrols the sand for algae, detritus, and small invertebrates.
Husbandry: The Halloween Hermit Crab constantly moves across the substrate and picks at algae and detritus. It should be provided larger snail shells to switch into. This species can kill ornamental snails. It should be provided an algae substitute (Spirulina) if little is available in the aquarium. It is reported to damage coral polyps, especially if algae is limited.
