Blue Leg Hermit Crab (Clibanarius tricolor)
Max Size: 1 inch
Reef Compatible: Yes
Minimum Tank Size: 5 gallons
Despite its small size, the Dwarf Blue Leg Hermit Crab, or simply the Blue Leg Hermit Crab (Clibanarius tricolor), is a mighty scavenger. This omnivorous creature fearlessly navigates even the tiniest crevices and openings within live rock, diligently consuming troublesome algae such as hair algae and cyanobacteria. In this process, it also contributes to sand substrate aeration, promoting the growth and activity of beneficial bacteria.
With its striking red-banded blue legs, this Hermit Crab adds a vibrant touch to any reef aquarium. Sporting claws of equal size, it seeks refuge in abandoned snail shells for its home. However, it's worth noting that if the Dwarf Blue Leg Hermit Crab is in need of a new dwelling or lacks sufficient food supplies, it may resort to attacking snails to acquire their shells or consume them as a source of sustenance.
To maintain a balanced diet, supplement the Dwarf Blue Leg Hermit Crab's meals with dried seaweed if the algae supply is inadequate. Although highly effective scavengers, due to their small size, it's beneficial to keep them in groups, especially in larger aquarium systems. This ensures they can thrive and continue their valuable scavenging and algae-controlling activities within the tank.
