Julian Campbell –
Grew quickly in my 48-inch tall aquarium. The leaves are dense and add great visual depth. I didn’t use CO2 and it still did well under moderate lighting. Only needed to add fertilizer occasionally.
Claire Burgess –
Great for background in a large tank. The plant spread out nicely and stayed healthy even with low-tech setup. A bit tall, so I made sure to leave space at the top.
Vanessa Hodges –
Very satisfied with the growth and appearance. It’s one of the few plants that can grow tall without needing extra lighting. Easy to maintain and looks stunning in a paludarium.
