The plant adds a lot of visual interest with its colour changes. I’ve kept it under medium-high light and it’s grown well in the midground. The leaves are fine and the red tones appear after a few weeks of strong lighting.
Dominic Brown –
It’s a nice addition to my nature-style aquarium. I trimmed it every few weeks and it responded well. The colour shift is subtle but noticeable over time. A bit of CO₂ helps, but not essential.

I love the way the leaves look under bright lighting. The copper and red hues stand out in the background. Easy to grow and maintains its shape with regular pruning.
