Grew quickly in my 10-gallon tank with just regular lighting. Trimmed it low and now it covers the bottom nicely. Very easy to maintain and looks natural.
Amelia Skinner –
I started with a small amount and let it grow taller. It formed a soft, feathery midground that adds depth to the tank. No issues with water parameters or lighting.

Perfect for beginners. The plant stays healthy even with fluctuating light. I love how it fills the tank without needing extra care.
