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.
(This works for MY hermit crab) Put a small spoon of peanut butter on a flat sea shell and they go nuts! they LOVE playing in it.
No hermit crabs need high humidity (70-85%)
No
Yes. But, the older crabs may bully the younger ones. And a larger tank would be a necessity.
Put lots of climbing things like vines and plastic plants in the terrarium hermit crabs love climbing. Put huts and caves for shelter and a bowl of freshwater and a bowl of saltwater so that they con drink and fill their shells as needed. You will need about three inches or more of sand so that they can dig.
do hermit crabs perfer to have some light during the night or per darkness?
Land hermit crabs don't, they put them on damp sand at low tide, when the tide rises it carries the eggs away.
well... nothing hermit crabs don`t eat crickets
Hermit crabs do not 'go to the bathroom'. In other words hermit crabs DO NOT POO. I have had hermit crabs, and I know they definitely don't poo. Hermit crabs use all the energy and nutrients from their food and turn it into vitamins for the body. Hermit crabs are great pets, as there is no stinky poo to clean out!!!
Marine hermit crabs live underwater and can sometimes be found in tidepools. Land hermit crabs do not live in the water but need fresh and salt water to survive.
no we had over ten hermit crabs in one cage and they were all fine.:) since they are both different sizes you should keep an eye on them but you shouldn't worry because hermit crabs are very social animals.
they both have two claws one big claw one small claw.RETARD
