I need some help. A couple months ago I bought a plant for my aquarium. It was unique and different and there was only 1 available. The guy at the store said it was imported and that's all I can remember about it. I went to 2 different places, including the one I got the plant from, and no one knows what the plant is called or if they can order again. The closest I have found online without a name is a Brazilian Pennywort, but the leaves don't match exactly.
