🌿 Overview

Hydrocleys nymphoides is a soft, floating freshwater plant native to South America. Its green oval leaves float on the water surface, while star-shaped white flowers bloom periodically, creating a visually striking surface coverage.

It is beginner-friendly, adaptable to a wide range of freshwater aquariums, and grows without CO₂. In high-light or CO₂-enriched setups, it forms dense floating mats and blooms more frequently. This plant is ideal for creating shade, providing shelter for fry and shrimp, and enhancing aquascape aesthetics.
