Quick Stats

Description

The Scarlet Hermit Crab (Paguristes cadenati) is a small, hardy invertebrate valued for its bright red coloration and peaceful temperament, making it a popular choice for both beginner and experienced aquarists. This hermit crab adds color to the tank with its vivid red legs and yellow eye stalks, bringing both beauty and beneficial algae-grazing behavior to the aquarium.

Native to the Caribbean and Indo-Pacific regions, the Scarlet Hermit Crab is an excellent choice for reef tanks as it typically leaves corals and other invertebrates undisturbed. It spends most of its time scavenging for leftover food, detritus, and algae, helping to maintain water quality by reducing waste and keeping algae levels in check. This active scavenger will also benefit from supplemental feedings, especially in sparsely populated or meticulously maintained tanks where natural food may be limited.

The Scarlet Hermit Crab prefers tanks with ample live rock and sand substrate, where it can find food and take shelter. It may require various empty shells to allow for growth, as it will periodically change shells as it increases in size. Providing an assortment of shells will help prevent conflicts over resources and encourage natural behavior.

With its easy care requirements and beneficial cleaning habits, the Scarlet Hermit Crab makes an excellent addition to most community marine aquariums, adding both functionality and charm to the tank.
