Oh, shoot, I just had my list of plants I was looking at when I started planting my tank like two days ago! I'll have to dig it up again, I had a bunch of those "tube" plants listed and which ones weren't really aquatic.
I felt so stupid when I found out from this forum that the purple waffle plant, Hemigraphis 'Exotica', was a land plant. Is it safe to assume that plants are not aquatic if it's rigid and holds up out of water?

TLT, there are some fully aquatic plants (like java fern) that hold up well out of water. I'd say the only real way to know is with research or a trusted source.
Well, I guess I got screwed too because I bought one of these yesterday from Petsmart. Topfin actually had a ton of plants in the little plastic containers with gel so I figured what the heck.:wall:
Aluminum plant (Pilea cadierei) is one that lots of people get suckered into. Its not the customers fault either. The plants are almost always displayed in tanks completely submerged in water and their usually under some vague or misleading tag like "assorted aquatic plant". Its pretty dishonest if you ask me, and it should be illegal.
You have a good point TLT. Most aquarium plants would flop over if they weren't in water, yet there are some who can stand upright in air. Examples would be Anubias, Java Fern, and after a while, Dwarf Sag.
There are also a few kinds of moss that are non-aquatic that are commonly sold online. The only ones that come to mind is 'splacho' something and 'star moss'.
