 Blue-Leg Hermit Crab (Clibanarius tricolor) — Reef Tank Essential

The Blue-Leg Hermit Crab is one of the most popular and effective members of any reef Clean-Up Crew (CUC). Small, active, and endlessly curious, these tiny workers keep your reef spotless by consuming algae, detritus, and uneaten food from rocks and sand.

Each crab is hand-selected and shipped from trusted suppliers to ensure top health and reef safety. Perfect for nano and mid-sized reef systems, from 10 to 100 gallons.

 Why You’ll Love Blue-Legs

• Active Algae Eaters: graze on film algae, diatoms, and cyanobacteria.
• Detritus Control: consume leftover food and organic waste before it decays.
• Reef-Safe: won’t harm corals or fish when well-fed and provided with spare shells.
• Visually Engaging: constantly moving and cleaning, adding personality to your reef.
• Natural Maintenance: part of François Neo’s “Nature First” reef-keeping philosophy.

 Kit Options Available

• 5-Pack: Perfect starter set for nano tanks (5–10 gallons)
• 10-Pack: Great for 10–20 gallon systems
• 30-Pack: Balanced Clean-Up Crew for 30–40 gallon reefs
• 50-Pack: Ideal for 50–75 gallon mixed reefs

François’ Rule: 1 Blue-Leg Hermit per gallon is the perfect ratio for balanced natural cleaning.
