First, land hermit crab salt water should be mixed according to package directions with a marine-grade salt mix such as Oceanic or Instant Ocean (you can find these online & at pet stores). Secondly, you should not bathe your land hermit crabs unless they are fresh from a pet store or have an issue like mites. Instead, you should provide a "pool" or dish deep enough for them to get in and dip the edge of their shell in to bathe themselves when they need to. Over bathing can result in fatal stress and/or messing with the concentration of fresh and salt water in their shell. Third, if you do have to bathe your crab, the only way you should use salt water is if you rinse them with fresh water after, too much salt water on their skin can be harmful. Remember, all hermit crab water should be treated to remove chlorine and chloramines; distilled water works great or you can buy a tap water conditioner.
1/8 cup per liter.
"No, they need salt water."
No, they don't unless there is a problem and your hermit crab has chosen to surface molt. In that case, he needs darkness and the best thing to do is give him a hidey such as a cocohut or other shelter so he can keep himself in darkness. Never ever disturb a molting hermit crab if it can be avoided. if a crab does surface molt, it is vital that you section him off from any other crabs you may have. This includes keeping them from being able to dig down under a barricade, as a molting crab gives off a very enticing smell (which is not an issue when they bury to molt) which may attract other hungry hermit crabs who will steal the shed exoskeleton of the molting crab who needs to eat it to regain strength. The newly molted hermit crab is also extremely soft and vulnerable, and could also become a target of another hungry hermit crab. for more hermit crab information you can rely on: http://www.hermitcrabparadise.com
Hermit crabs will eat more drink more and bath in the SEA salt more they will grow a sack under its arm that has the food it will need when it undergoes this process. Then they will bury itself DO NOT dig them up! If you think they are dead and your tank smells like dead fish then it is dead. Hermit crabs molting can take from weeks to months. When it comes out of the substrate when it is done molting it will have it's old exoskeleton DO NOT take it away, it has all the vitamins it need i know its gross but let them eat it. After that they will bath more in SEA salt water and once their new exoskeleton has hardened they wont bath in it was much.
No, unfortunately they can't... Hermit crabs lay their eggs in the ocean, they are born without shells, and eat plankton. If you have a very large aquarium, and can manage to make a mini-saltwater ocean inside as well as dry land, it could be possible... Remember that the ocean must have a proper amount of salt! (table salt is harmful to hermit crabs too...)
All hermit crabs love sea salt. DO NOT GIVE IT TABLE SALT. IT WILL KILL THE HERMIT CRAB. All hermit crabs should have a small bowl of fresh water & salt water. You can purchase salt water from your local pet store. If you want fresh water you should give your hermit crab bottled water. Faucet water contains toxins which are bad for any pet. They will not die, but it's better to be safe than sorry.
unless there not enemies then yes.
If your question is "Why wont your hermit crab eat". - Your hermit crab IS eating. hermit crabs are nocturnal animals (like bats). They mostly like to come out of their hiding place at night. So when you're sleeping, they are having a party, eating & drinking their fresh and salt water.
Nothing exept have babbies faster
if you keep it in a bucket of salt and water, it will live.
You should put distilled water and and sea salt water in your crab's tank. It shouldn't be deep enough for the crab to submerge itself in, but they have to be able to get out or they can drown. Hermit crabs need distilled water because the clorine in tap water burns their modified gills and sofacates them, same with table salt. use SEA salt.
Land Hermit Crabs consume fresh water. It is suggested by some pet stores to have two watering dishes. One for bottled fresh water and the other for bottled salt water. The hermit crab can choose between the two depending upon the nutrients it feels it needs. If you do not have salt water- that is fine, it is not necessary.
