As aquarium fish
Number of fish
A good many of these fish 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.
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.
