I have three large-clawed freshwater crabs, I'm not sure what species. I had tried putting them in my goldfish tank, but within a few hours two of them had climbed up an air hose and were sitting on top of the screen cover. Needless to say they went back in their own tank.
They are very cool and act very differently than the SW crabs that I have.
