Looks like a Brazil sword, Borneo swords (Spathiphyllum sp.), which isn't an aquatic plant. Here's other pictures online for better photo comparison.
See photos 2-7. LFS sell them as bog plants, but they're not true aquatics.
EDIT: The plant infront of the latest photo doesn't look aquatic either...
