The only anemones or urchins that go in freshwater would be plastic

Maybe the tank has some hydras in it and that's what you're thinking of? Those guys are freshwater, but related to anemones. This is what the look like: http/mcdb.colorado.edu/labs/jones/MCDB4650/hydra3.jpg

anemonies and corals are cnidarians, there are some cnidarians that can go into FW, Many species of hydra most noteably the green and brown hydra can, but they are very small and do not build skelitons seeing as how there are few minerals in fresh water for them to build with. there are species of ghost shrimp that can go from fresh to salt but you'd be better off just going with fresh water or salt water shrimp as most of the shrimp that can go back and fourth like it in the middle.
