Both the Aqua Fern and the Peacock Fern are non-aquatic. Regardless of which store sells them, all the tubes come from the same company. I compiled a list of them several years ago, but I can't seem to find it anymore.
Do you know what company?
The aqua fern might be java fern. I got one of the tubes that said aqua fern and it turned out to be java fern, as long as the little name under the name "aqua fern" says "microsorum pteropus" it is a java fern. Most of the anubias and amazon (not argentina) swords are really big actually and look healthy from what I've seen at my PetSmart. All the others I would stay away from.
The ones at work don't look like java fern, but like a regular ol' fern, complete with fronds and everything. I'll check the scientific name tomorrow when I go in to be sure though, but I don't always trust the scientific name they put on labels (my two turtles I adopted where labelled as Pelusios subniger, and they're really Pelomedusa subrufa and ever since I've not trusted the labels).
