Is there any hermit crabs or fiddler crabs?.

Hermit crabs no, but fiddler crabs yes.

Stock varies as people purchase. .. best to call store to ask about their current stock

Call ahead and ask. They only get them when the crabs are in stock

I didn't see any whenever I've gone there? I really don't think they have any of those.

No

Both I think

I saw fiddler crabs in the back tank had quite a few
