No, they need distilled water to drink. They also need salt water to harden their exoskeleton. NEVER use table salt it will burn their lungs! Use SEA salt instead because its found in the ocean
Put the water in a hermit crab pool from a pet store, but make sure if you use tap water to get a Purifier Liquid to kill those nasty chemicals.
I saw a hermit crab on the beach.
Hermit crabs use gills to breath.
A hermit crab.
hermit crabs use their claws to grab food
yes you can. only you have to use very very shallow water!
You will need a tank, substrate, a food dish, 2 water dishes, ( for fresh and salt water) hermit crab food, a place for them to hide in.
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.
Well for the safety of your hermit crabs i would use the basic rule of 1gallon of tank space per hermit crab..... so you could get any size you want.... but lets say you had a 10gallon tank so you could have 10 hermit crabs in the same tank.
It shouldn't be about to lay eggs. (I am assuming you have hermit crabs in a aquarium.) It has been proven that they need an ocean to lay eggs and therefore cannot lay eggs in captivity. Even in zoos they can't lay eggs.
If you mean will it kill the crab, no. However the hermit crab probably won't be able to use most toys. Depending on what it is.
Never give/spray your hermit crab with tap water. It constricts their gills and WILL kill them. Use bottled or distilled water, you can also buy hermit crab water conditioner at your local pet store for about 3 dollars. It will give instructions on how much to put into the tap. Salt water is mostly for soaking, so just put some in a shallow bowl in your crabitat, as well as fresh water, and make sure that its shallow enough so the smallest crab won't drown but the biggest crab soak in it. Hope that helps! :)
