Number of fish

A good many of these hermit crabs can exist in the same aquarium, but they will kill each other without insufficient space and/or food.

Count therefore on about 40 gal (150 liters) each, if one desires several in one tank.

Descriptions and further reading
Family description (Paguroidea)

Hermit crabs can be lots of fun, but are not particularly useful in the tank.
They are generally easy to keep, but not all species are algae eaters, some eat mostly zooplankton off the rocks.

Remember that they require new shells to grow.
