Scarlet Reef Hermit Crab: The Vibrant Algae Cleaner
The Scarlet Reef Hermit Crab (Paguristes cadenati) is one of the most popular, colorful, and beneficial members of the marine aquarium clean-up crew. This species is immediately recognizable by its bright red legs and claws, which contrast beautifully with its yellow or yellowish-orange eyestalks and a relatively small, orange-red body.
Native to the Caribbean and Western Atlantic, the Scarlet Reef Hermit Crab is highly valued by hobbyists for its voracious appetite for nuisance algae. Unlike some other hermit crabs, which can become aggressive toward tankmates, this species is generally peaceful and is less likely to prey on snails for their shells, provided ample empty shells are available.

This hermit crab has been a game-changer in my tank. It constantly eats algae without bothering my snails or fish. I’ve provided plenty of empty shells, and it’s been very active and calm. A must-have for any reef tank.

I bought this crab to help with algae buildup. It’s very colorful and active. It doesn’t seem to eat anything other than algae, which is perfect. Just make sure to have enough empty shells available.

The crab arrived healthy and has been very easy to care for. It’s not aggressive and spends most of its time cleaning the glass and rocks. I love the vibrant red color and how it adds to the tank’s appeal.
