Electric Blue Knuckle Hermit Crab | Calcinus elegans

SHIPPING RESTRICTION: THIS INVERTEBRATE MUST BE SHIPPED VIA UPS NEXT-DAY AIR SHIPPING!

The Electric Blue KnuckleHermit is a medium-sized species of hermit crab native to the Indo-Pacific. They will not harm most complex macroalgae, though larger specimens may eat soft or thin algae.

Caution: May consume Cymopolia barbata and other small calcareous macroalgae.

*Disclaimer: while we personally have never had our hermit crabs do sufficient damage to most macroalgae species, there is always a chance of hermit crabs taking a liking to a particular macroalgae. These hermit crabs may cause minor damage to some soft/thin macroalgae species in the process of cleaning. MosaicMacros is never responsible for damage to algae by hermit crabs or other invertebrates.
