🦀 Blue Leg Hermit Crab (
Clibanarius tricolor
)
Size: Up to 1 inch
Lifespan: 2+ years
Behavior: Active, peaceful scavenger; may fight other hermits for shells
Diet: Algae, detritus, leftover food—great for cleaning tanks
Tank Needs: 5+ gallons, provide plenty of empty shells to prevent fighting
Water: 72–78°F, pH 8.1–8.4, salinity 1.023–1.026
Compatibility: Reef-safe; good with corals, snails, and small fish (but may attack snails if no spare shells)
Fun Fact: Bright blue legs with orange banding make them very colorful and popular in reef tanks.
