Ceratophyllum Demersum, also known as Hornwort or Coontail, is a versatile plant that can be used as both a floating plant and a stem plant. The plant does not have roots but anchors itself via root-like rhizoids. Due to its rapid growth, it absorbs excess nutrients and helps prevent algae growth. Suitable for both cold and tropical aquariums.

✂️ Care
Let the plant float freely or plant it loosely in the substrate — it does not need roots. The plant grows quickly and regularly forms side shoots. Prune regularly to prevent overgrowth; broken parts will grow into new plants. Liquid fertilizer like Sera Florena supports healthy growth.
💡 Planter tip
Ideal for new aquariums — its rapid growth absorbs excess nutrients and helps prevent algae growth. Provides excellent hiding places for young fish and shrimp. Suitable for coldwater aquariums.
