Scarlet Reef Hermit Crab

Posted on Wednesday, March 3rd, 2010 at 12:03 pm by

The scarlet reef crab, Paguristes cadenati, is appropriately named for it’s bright red legs, which are contrasted against its yellow face. Also known as the Red Reef or Red Legged Hermit Crab, this reef-safe crab has an appetite for algae and detritus, and is an excellent member of any clean-up-crew (CUC).

The Scarlet Reef Crab can be found in the Caribbean, Eastern Asia, Indo pacific and Western Atlantic, roaming around while scavenging for various algae, decomposing marine life-forms and detritus. In the reef tank, the scarlet crab will eat almost any available algae and left-over food, which makes them an excellent choice. However, as with any hermit crab if a supply of empty shells is not available, the Red Legged Hermit Crab may “borrow” one from one of your snails. And of course, copper and significant fluctuations in water parameters (pH, salinity, Alk, etc) will not be tolerated by this species.
