From what I know fiddler crabs need a semi-aquatic environment. It might be
a good idea to save them from the petshop if you're willing to take care of
them. I've seen them at pet shops as well but they're always in
semi-aquatic environments and they're usually half-way out of the water.

Sadly, these were not. They were in a freshwater tank with no means
of escape. No plants, rocks, gravel--nothing but bare tank. They
were clearly trying to escape but there was no way out.

It just seemed very sad. I won't patronize that fish store, to be
sure.
