Scarlet Hermit Crab
The Scarlet Hermit Crab has a larger adult size than most hermits but not so large that you have to worry about them getting into trouble. They have a vibrant red coloration that makes them a favorite among hobbyists. They scavenge fish waste, algae, and detritus that have been deposited on live rock and substrate. The Scarlets are even known to snack on the nuisance hair algae and 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 Red Tips are very hardy but are sensitive to copper. Make sure to never add copper-based medications into an aquarium with invertebrates.
