Electric Blue Hermit Crab
Calcinus elegans
Paguroidea (Hermit crabs)
Hermit crabs can be lots of fun, but are not particularly useful in the tank.
They are generally easy to keep, but not all species are algae eaters, some eat mostly zooplankton off the rocks.
Remember that they require new shells to grow.
