✂️ Care
Gently rinse the gel under lukewarm water and plant several rosettes with 3–5 cm spacing in the foreground. Plenty of light is crucial — with too little light, the Downoi will grow upwards and lose its star shape. CO₂ and a nutrient-rich substrate promote compact growth. Liquid fertilization such as Sera Florena supports healthy development.
💡 Planting Tip
Ideal for Iwagumi and Nature Aquarium layouts. Combines beautifully with Anubias Nana on stone or Bucephalandra on wood for maximum contrast.
