java fern salt tolerent???

[Mbargas]

i used to have some in my tank but i got rid of it when my first archer died becuase i thought the fern was to blame anyway it did fine but now i have a huge sumatra fern that is turning brown and dieing so i am going to add a 8 inch and a 6 inch java fern but will it survive the sg is 1.010

i have yet to see any scientific evidence that the Java Fern is a true brackish water plant, i.e. that it can tolerate a wide range of salinities from FW to almost marine. There are a lot of anecdotes from so-called experts who claim that it can tolerate fairly high salinities, but no hard data. If anyone can show me a a study of its salt tolerance, I would like to see it.
