Yes! I have that plant in both of my aquariums (with only the roots in the water though) and its doing great! Have been using this plant for months & months; Check out my riparium thread. Great for nitrate removal... Its called Pothos, also known as Devil's Ivy.
No it is still a terrestrial plant and will die if kept fully submerged. The plant only survived for a couple a weeks last I tried. Then it started getting black spots on the leaves. I suggest you just arrange it so the leaves are out of the water but have the stem still in.
