I have been getting my plants from someone on aquabid.com , mikeswetpets is awesome his plants are so healthy and he dips them is something to kill the snails before shipping. His prices are great also. If you want a awesome plant get one of his Banana plants mine has been growing beautiful big colorful leaves since I got it. Although I trust him I still QT any plants for at least a week or more in tap water and before putting them in the tank I pour in some old tank water so they can get used to it got a couple of days. Always check out any feedback when you buy from someone.
One of the Banana leaves grew to the top of the water line and Perseus has been making his bubblenests under and around it , I just love this plant and easy to care for I am getting another one for sure. I think it does like good light I have a 650K bulb in my hood . You dont have to worry about planting it in the gravel or anything it puts out its own roots the will go into the gravel on their own.
