Several marine species of hermit crabs are common in the marine aquarium trade. Out of the approximately 15 hermit-crab species in the world, these are commonly kept as pets: The Caribbean hermit crab, the Australian land hermit crab, and the Ecuadorian hermit crab. Other species such as Coenobita brevimanus, Coenobita rugosus, Coenobita perlatus or Coenobita cavipes are less common but growing in availability and popularity as pets.

These omnivorous or herbivorous hermit crabs can be useful in the household aquarium as scavengers, because they eat algae and debris.

Hermit crabs were once seen as a "throwaway pet" that would live only a few months, but species such as Coenobita clypeatus have a 23 year lifespan if properly treated, and some have lived longer than 32 years.

Feed care for hermit crab

You can feed your hermit crab commercial hermit crab food from your pet store, but you should also supplement its diet with a variety of other foods. Here are a few guidelines:

    * they like various kinds of fruits and veggies, such as pieces of lettuce, grapes, bananas, apples, etc. These should be removed the next day since they are perishable
    * they also enjoy pieces of dry cereal, popcorn and crackers
    * avoid giving them any extremely sugary or salty foods
    * you should NEVER give them meat

You should have fresh, clean water in the cage at all times. Keep the water in a shallow dish that the hermit crabs can enter and leave easily. Avoid using dishes that have are slippery, wobbly, or too deep, and don't use metal dishes.

A land hermit crab can drown in its water dish if it cannot climb out. To avoid this problem, you can fill the dish with rocks or a piece of driftwood to help the crab climb out.

Hermit Crab Behavior

Hermit crabs are nocturnal, so they may seem inactive during the day. But if you wake your hermit crabs up during the day, they usually sleep during the night. It is important for a hermit crab's well being that they get exercise outside the the cage.

I found that since I started to let them out of their cages to roam free, they seem to live longer on the average. Usually, hermit crabs will go towards dark areas, such as under a couch, since they are nocturnal. If you do let them out of the aquarium, it is important that you watch where they go.

Hermit crabs seem to like having the freedom to move, but they always return to the same location eventually. I feel that giving crabs the freedom to wander around is a more natural lifestyle for a crab to live in.

Since I started to let my hermit crabs spend most of their time outside the cage, they live longer. They live between 1-4 years on the average; where as before, I was lucky if they lived for 6 months in the aquarium. And I have noticed that large hermit crabs are not aggressive towards smaller hermit crabs. Usually, hermit crabs are only aggressive to hermit crabs of similar sizes.
