Size of hermit crab aquarium
To keep a marine hermit crab, you will need an aquarium that is at least 10 gallons large. Taller can be better than longer because marine hermit crabs love to climb on rocks so make sure to put some rock in your aquarium. Try to provide around 1-2 pounds of live rock or coral per gallon of water volume. Hermits also prefer some kind of substrate where they can dig around in so either use sand or crushed coral.

Asking yourself what do saltwater hermit crabs eat? Most often found in the aquarium hobby, species like the Dwarf Blue Leg Hermit Crab and Halloween hermit crab, also known as the Electric Orange Hermit Crab are omnivorous species.

Hermit crabs and live rock
When watching your aquarium, you can often see your hermit crabs plucking your live rock but not everything they pluck of your live rock is eaten. After eating, hermits will send a part of it back into the water column in a plume of debris and will re-establish elsewhere. That is, if the nutrients allowing it to grow aren’t eliminated by your filtration system.
