Halloween Orange Band Hermit Crab (Ciliopagurus strigatus)

The Halloween Orange Band Hermit Crab (Ciliopagurus strigatus) is a striking reef-safe scavenger dressed in bright orange-and-red banded legs. Beyond the eye-catching color, it's one of the hardest-working members of a saltwater cleanup crew — constantly grazing nuisance algae and sifting detritus from the rockwork. Add it to the rest of your saltwater livestock to keep your reef tidy.

Care Guide

• Care level: Beginner — hardy and undemanding once acclimated.
• Minimum tank size: 10 gallons of established saltwater with live rock to graze.
• Water temperature: 72–78°F.
• pH: 8.1–8.4.
• Salinity: 1.023–1.025 specific gravity.
• Reef safe: Yes — it won't bother corals and actively eats film algae, hair algae, and detritus.
• Diet: Omnivore and algae grazer; supplement with dried seaweed or sinking foods if algae runs low.
• Extra shells: Provide a few empty shells slightly larger than its current one so it can trade up as it grows.

Specifications

Compatibility

Peaceful and reef-safe, the Halloween Hermit Crab is an ideal cleanup-crew member alongside:

• Algae-eating snails like turbo snails and nassarius snails
• Other reef-safe crabs such as red leg hermits and emerald crabs
• Peaceful reef fish and corals

Keep a supply of empty shells on hand — hermits occasionally squabble over shells, and offering spares prevents them from bothering your snails. Avoid large predators that prey on crabs.

Recommended Foods & Supplies

• Nori Seaweed Sheets — a great supplemental graze when algae is scarce
• PE Saltwater Pellets — sinking food it can scavenge
• Red Sea Salt Mix — for stable water changes
• Seachem Prime — dechlorinate and detoxify new water
• Build your cleanup crew from our saltwater livestock

FAQ

Is the Halloween Hermit Crab reef safe?
Yes. It won't harm corals and spends its time grazing algae and detritus, making it a valuable cleanup-crew member.

What does it eat?
It's primarily an algae grazer and detritivore. In a tank with little algae, supplement with dried seaweed or sinking marine foods.

Do I need to provide extra shells?
Yes — keep a few empty shells slightly larger than its current one so it can move up as it grows, and to discourage it from eyeing your snails' shells.

Will it bother my snails or other inverts?
It's generally peaceful. The main thing to manage is shell availability; with spare shells provided, conflicts are rare.
