At my LFS, their planted tank had both Jungle Vals & dwarf sag. I went to another specialty fish store, and they said it's not recommended to have both of those plants in the same tank (that they produce something that is harmful to the other).

Can someone confirm or deny this?

I don't see anything wrong with it. They're often used in the same aquascapes too. The worker must have had a bad experience with while keeping them in his tanks may have killed them due to bad water quality or something.
