Scarlet Hermit Crab
The Scarlet Hermit Crab, known for its striking red body and legs, is an invaluable addition to marine aquariums, diligently scavenging detritus and aerating sand beds. Originating from the Western Atlantic Ocean, these hardy crabs thrive in shallow reef environments. They typically grow to 1 to 2 inches in shell length and have a slow but steady growth rate in captivity. Feeding them is straightforward, as they eagerly consume algae, detritus, and various foods, contributing to the tank's cleanliness.
Scarlet Hermit Crabs are compatible with Nassarius and Astrea snails, Peppermint Shrimp, Blue Leg Hermit Crabs, and Clownfish, fostering a diverse ecosystem. To ensure their well-being, provide a tank of at least 5 gallons with stable water conditions and gentle to moderate water flow. Sourcing from Saltwaterfish.com guarantees high-quality, healthy specimens, enriching your aquarium's biodiversity and maintaining its vibrancy.
Habitat
The Scarlet Hermit Crab (Paguristes cadenati) hails from the Western Atlantic Ocean and is commonly found in shallow reef environments and intertidal zones. These hardy hermit crabs are well adapted to life on the ocean floor, and they play a vital role in keeping the substrate clean by scavenging for food and detritus.
Size and Lifespan
Scarlet Hermit Crabs are relatively small, typically growing to a maximum size of about 1 to 2 inches in shell length. In captivity, they have a lifespan of several years, making them a long-lasting and engaging addition to your marine aquarium. Regardless of size, they are voracious cleaners.
Slower Growth Rate
The growth rate of Scarlet Hermit Crabs is relatively slow and steady. Diet, water conditions, and shell availability influence their growth. With proper care, they can gradually increase in size over the years.
Dietary Needs in Captivity
Providing a balanced diet that includes marine pellets, algae wafers, and occasional meaty foods like brine shrimp or fish flakes is recommended to keep them healthy.
Compatibility with Other Fish and Invertebrates
- Nassarius Snails (Nassarius spp.): These burrowing snails help stir and aerate the substrate while scavenging for detritus, making them suitable companions for Scarlet Hermit Crabs.
- Astrea Snails (Astrea spp.): These snails are efficient algae grazers, contributing to maintaining a clean and algae-free aquarium.
- Peppermint Shrimp (Lysmata wurdemanni): Peppermint shrimp are known for their ability to control pest anemones in your tank while coexisting peacefully with Scarlet Hermit Crabs.
- Blue Leg Hermit Crab (Clibanarius tricolor): These hermit crabs share similar care requirements with Scarlet Hermit Crabs and can be added for variety.
- Clownfish (Amphiprioninae): Clownfish often form symbiotic relationships with Scarlet Hermit Crabs, seeking refuge within their shells.
Tank Requirements
To ensure the well-being of your Scarlet Hermit Crabs, it's essential to provide the following tank conditions:
- Minimum Aquarium Size: A suitable tank for Scarlet Hermit Crabs should have a capacity of at least 5 gallons, providing ample space for a small group of these crabs.
- pH: Maintain a stable pH level between 8.1 and 8.4.
- Salinity: Keep salinity levels stable at 1.023 to 1.025.
- Water Temperature: Maintain a temperature range of 72-78°F (22-26°C).
- Number of Scarlet Hermit Crabs per 10 Gallons: Typically, you can house 5-10 Scarlet Hermit Crabs per 10 gallons of tank capacity.
Water Flow
Gentle to moderate water flow is recommended to replicate their natural habitat conditions and ensure efficient nutrient distribution.
Other Common Names
The Scarlet Hermit Crab is also known as the "Red Leg Hermit Crab" due to the distinctive red coloration of its legs.

Bought 2 scarlet hermits that are just a tad small for me. At first they both hid. Then they came out and joined each other. Then they went in 2 different directions and the last few days I've only seen one of them. Hope the other is O.K. I think next time I'll go for a bit larger crab. They're getting along with their tankmates and have added not only to the "cleanup crew" tasks, but are a pretty and active addition to a normally slow and quiet seahorse tank.

Great addition to cleaner crew, and are cooler water species as well

Although these guys have shown no interest in my Cyanobacteria (for which I bought them), they are extremely active as advertised. My main problem is that they like to flip my snails upside down, which causes me to be continually righting the snails that can't right themselves.
