I have it in a low light low tech tank, leaves on lower parts of stem melt, but upper parts thrive and grow across the top of the tank. Also if left to grow out of water, the leaves become more spaced apart and larger.
I got 4 stems from aquariumplants.com. I hope that's what they sent, anyhow. I received a broad leaf very different emersed looking plant. Can anyone tell me how long it will take for it to change to it's submersed form? It has been over 2 weeks
