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.
no they will not eat red clawed crab!
no
Yes they are scranvengers
In this situation, how hard have you thrown it?
I don't think I would chance it, the land crab could all into the water. Good luck!
Yes they do. My Adult apple snail was ripped apart by my red clawed crab. So based on my experience, I wouldn't mix them together.
it depends how big it will get
hermit crabs should not be put with other animals and your hermit crab needs a better home. Glad i could help p.s 35cm wide tanks can hold 3 hermit crabs
yes
No, these two animals cannot live together well. The turtle will often attack the crab in an effort to eat it, and it is not advisable for them to live in the same tank together.
it eats people
No but they can eat guppys
