It is vital to not fill the aquarium up with water, as the hermit crabs are land crabs. Place either shell grit or aquarium sand over the floor of the aquarium. Try to keep the sand dry at all times. Hermit crabs love to climb, so include driftwood pieces or mangrove roots within the aquarium to provide some entertainment. They need this to keep their gills moist and to breathe properly.
If the air is too dry, your hermit crab might become inactive and suffocate. Two types of water needs to be provided at all times for your hermit crabs.
Have fresh water in one bowl for drinking, and in another bowl have sea water for bathing. Sea water can be made up with Hermit Crab Salt and water follow the measurements on the packet for the correct ratio. Use heavy, solid bowls for the water as hermit crabs love to climb and can tip over the water if a lightweight container is used. Food Hermit crabs need to be fed daily and in little amounts at a time to ensure the food is fresh.
Suitable foods to feed your hermit crab are fish pellets, breads, cereals, apples and other fruits, and shredded coconut. Moulting Hermit crabs moult their outer skin usually twice a year. The old skins that your hermit crab moults off are usually eaten. Allow them to eat their old skins as this is a rich source of calcium.
Shells Usually after moulting, hermit crabs will change the shell they the live in. Provide the hermit crabs with some spare shells in the aquarium. It is essential you provide shells that are slightly larger than the previous one as your hermit crabs are continuously growing. Fighting Fighting can be an issue if your aquarium is over populated and crowed.
