Every argument against this only goes as far as to say "true brackish water contains trace elements that a crab needs that aren't found in freshwater or aquarium salt."
Nobody ever says specifically what these trace elements are or why, exactly, they're vital to a fiddler crab's health. If anybody would provide a specific, scientific explanation, I would gladly change my position.
But for now, my firsthand experience is that with a little added attention and care a fiddler crab can thrive in freshwater.
Here's an article on choosing (mostly freshwater) tank mates for you fiddler crab if you're interested... Best Fiddler Crab Tank Mates: What Fish Can Live with My Fiddler Crab? - Associated Content |
calcium, alk, and mag are the main 3 you will find in saltwater. there are also trace elements which i would come to believe are needed for proper healthy growth and developement of the shell.
the big question is, how long have you had it in alive for? i think its more like, you can put neon tetras in alkaline waters but they would thrive in something more acidic and blackwater.
