The Scarlet Hermit Crab, Paguristes cadenati, has a characteristic red body and legs that peek out through its shell. It is a wonderful cleaner and scavenger that will help rid your tank of unwanted detritus and aerate sand beds. They love to climb on rockwork and will often search for excess shells in case they want to make a switch. The Scarlet Hermit will also molt as it grows. Completely reef safe and peaceful, the Scarlet Hermit is a great addition to any tank.  

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.
