Zebra Hermit Crab
The Zebra Hermit Crab is the trifecta: small adult size, reef safe, and hardy. Their black and white legs look great while they scoot around. They scavenge fish waste, algae, and detritus that have been deposited on live rock and substrate. The Zebras are even known to snack on the nuisance Red Slime Cyanobacteria. These little guys can find their way into even the smallest of spaces. Like all hermit crabs, they make their home in empty snail shells, so be sure to have an array of empty shells available for them to move into when they grow. They will also take housing matters into their own pincers by occasionally eating a snail and taking that shell over; smaller snails are especially at risk. The Zebras are very hardy but are sensitive to copper. Make sure to never add copper-based medications into an aquarium with invertebrates.
