They cannot live with a land hermit crab because land hermit crabs live out of water so the fish would die (as you know) if it is out of water.
yes
yes although it would be wise to clean and disinfect it first, you don't know why your old crab might have died.
It'll go back to the sea or find a place that's filled with water you know that hermit crabs need water before they dry up!
water is the safest way to clean a cage. i would not take any chances with cleaning supplies because they may harm the animals. just soak/dry the cage with a towel.
He is becoming a hermit. A hermit lives near here.
No, Hermit Crabs and Fiddler crabs require two different environments. The Hermit Crab would drown in the water a Fiddler Crab needs. You can always ask your local pet store if there is any way possible though. Some hermit crabs live on land others live in water even land hermit need two enter salt water , fiddler crabs are brackish or fresh hermit crabs can't breathe in those environments
A hermit, a bachelor, a loner, or a recluse. it is just hermit
Don't do that! Hermit crabs may get out of their shell to change into a new shell or even get out to eat some lettuce or drink water from a water absorbed sponge. During that process who knows what the hamsters would do to the hermit crab. They're not meant to be in the same cage!
Why would you do that? That's cruel.
They live in the ocean - it would be a little difficult to drink freshwater.
Hermit Crabs live in sea water. Guppies are freshwater fish and will not be able to live in with hermit crabs. The crabs would no doubt eat whatever dead fish you give them.
