Blue eyed hermit crab (Calcinus sp.)

Family: Diogenidae

Care level: Easy

Temperament: Average

Reef compatibility: Reef safe

Max size: 6cm

Diet: Omnivore

Shipping size: Medium (approximately 3cm)

Blue eyed hermit crabs make a useful addition to most reef or fish only marine aquariums. They have very striking colors and are active clean up crew consuming algae, cyano bacteria, trapped or left over food as well as any dead or decaying plant or animals. 

These crabs are like most hermits in that they require spare shells to occupy whether for reasons of space or just a new home. Again like most hermit crabs they are generally peaceful providing food and space are available, all crabs are opportunistic feeders and may pick on weak snails etc. for food or for shells but are generally accepted as more good than bad.
