You do not have to be a genius, just do a little research. Online dealers of aquatic plants like me usually only sell true aquatic plants, or identify them correctly. Local independent stores, (not chains) sometimes know the difference between aquarium and terrarium plants.
I have decided to avoid places that aren't reputable for knowing anything about plants, or fish. I just placed a $100 order with aquariumgarden.com. I fully expect these plants will arrive, suitable for my aquarium.
