I bought three stems of Mermaid Weed for my 55-gallon tank. The leaves changed color beautifully under different lighting, adding a dynamic look. It grew well in medium light and I noticed more color variation after adding CO2. Easy to plant and maintain.

The plant arrived healthy and the stems were well-packed. It’s growing steadily in the background. I appreciate the color shift with changing light. Not as fast as Water Wisteria, but still impressive for a beginner.
