About Horned pondweed
Zannichellia peltata, also known as horned pondweed, is a perennial, herbaceous submerged aquatic plant that forms dense mats of slender, branched stems with thread-like leaves. Its small, greenish flowers are inconspicuous and develop underwater. It is ideal for freshwater aquariums or shallow ponds, providing a natural look and serving as a refuge for small aquatic organisms.
Native range
Tropical and subtropical regions of Africa, Asia, and Australia
Care tips
It requires moderate to high light for optimal growth, avoiding intense direct sunlight that can overheat the water. It prefers still or very gently flowing waters, with temperatures between 15°C and 25°C. The ideal substrate is sandy or silty, rich in nutrients, although it can anchor itself in muddy bottoms. A common mistake is not providing enough space for its propagation, as it can form dense colonies.
