how many freshwater crabs are there i know fiddler crabs but technically they are brackish
 
I am interested in this too and I have always wanted to have a crab paludarium! Looking forward to input from others!
 
There are quite a few really freshwater crabs, I suggest you try google. South America has many freshwater crabs, everything from swimming crabs to rock crab type crabs and even these things http://www.planetinverts.com/aegla.html many salt water crabs such as Blue crabs can not only live in freshwater they are being raised in freshwater ponds as a food crop here where I live in NC. Crabs can be very tough and some like blue crabs actually leave the ocean in favor of freshwater. I catch them routinely in freshwater along side blue gills and bass. So don't cross off a crab because technically it is brackish, brackish isn't a specific salinity, many of the brackish animals need such a tiny amount of salt that you couldn't taste it if you tried and few freshwater animals or plants would be affected by it. A great many people add more than enough salt to their other wise freshwater tanks to qualify them as brackish.
 
I've been doing an AC database. Here are the species forwarded by an AC member.
