Blue Leg Hermit Crabs are very well known for controlling various types of algae including hair algae and are considered to bereef safe. Blue Legs congregate in large numbers in the wild feeding upon many types of algae and do a wonderful job within a reef tank consuming algae as well as leftovers. Size is about a 3/8 to 1/2 inch shell.
Note.. We believe that Blue Leg Hermits should have;- Blue Legs with red and white tips. We do not a see lot of color variation with Blue Leg Hermits. Very little size or gender color variation. “Blue Legs” with green legs, are possibly another species; – perhaps C. vittatus. We very carefully select authentic Blue Legs.
