The leaves developed nicely in my tank after a few weeks. The fluted edges are very distinctive and the color deepened well under moderate lighting. I keep the water stable and it’s thriving.

Grew well in my 50-liter tank with standard aquarium lighting. The underside shows a nice violet hue, which adds visual interest. A bit sensitive to water hardness, so I adjusted my water parameters.
