Need help ID-ing hermit crabs! Are they reef safe?

[Shiva]

Hi everyone,

Could I request for your help in identifying these two new hermit crabs I got earlier today at my LFS. These guys started going at the algae in my aquarium from the moment they landed, but I'm not sure if they're reef safe. Please do let me know your inputs!

Hermits can be reef safe.
Hermits may not be reef safe.
Depends on who you listen to
