Brackish or fresh?

[Cr85dirtbik]

Hello, im interested on getting a crab or so in my tank. Question is are there any fully freshwater? Or all brackish? Because i have a corydora and clown pleco and im sure they dont like aquarium salt. I know my mollies and platies are okay with brackish, but id really love to get some sort of crab. New to the crabs and i know they need to dry out, breath air etc.

No one?

Not sure there are any pure freshwater crabs but I could be wrong. Fiddlers need some salt and land. Crays are a decent alternative but are destructive to the tanks stock. Could try a Mexican dwarf crayfish, very hardy and tame.

Thai micro crabs are fully freshwater.
