~ All About Brazilian pennywort ~
If you’re looking for a versatile and attractive aquarium plant, Hydrocotyle leucocephala is a fantastic choice. Also known as Brazilian pennywort, this plant is appreciated for its round, bright green leaves and fast growth. It adapts well to different tank setups, making it a great option for both new and experienced aquarists. Learning the basics of Hydrocotyle leucocephala care will help you keep this plant thriving. Cut stems transplant well, i.e. propagation is easy.
This plant grows well under moderate to high light. Brighter lighting encourages compact growth and rich green coloring, while lower light leads to taller, more leggy stems. One unique feature is that you can grow Hydrocotyle leucocephala floating at the water’s surface or rooted in substrate. As a floating plant, it provides excellent cover for fish and helps reduce algae by blocking excess light.
Hydrocotyle leucocephala is highly adaptable to different water conditions. It grows best in temperatures between 68–82°F and can handle a wide pH range. Because it grows quickly, it benefits from regular fertilization with liquid nutrients. CO₂ injection is not required but can speed up growth and enhance leaf size.
Left unchecked, Hydrocotyle leucocephala can spread across the surface, blocking light from plants below it, so trim it regularly so it does not outcompete it's neighbors.
As a companion plant, Lysimachia nummularia, commonly known as creeping jenny, can be used in paludariums or setups that combine aquatic and terrestrial elements. Its trailing stems and small, rounded leaves complement the shape of Hydrocotyle. Again, growth and your aquascape design must be managed, so trim regularly and check placement often. Keeping it near the edges or in above-water sections helps maintain a balanced layout and prevents it from overwhelming the aquarium design.
With consistent care and maintenance, Hydrocotyle leucocephala remains a vibrant, fast-growing plant that enhances both the appearance and balance of your aquarium.ФФ
This plant grows quickly, often adding several inches per week under good light and nutrient conditions. It can spread across the surface or climb upward, so regular trimming is needed to keep it in shape.
Yes, it can grow in ponds and outdoor water gardens as long as the climate is warm and frost-free. It thrives in shallow water or along pond edges, where it can root or float freely.
Yes, it’s completely safe. Its leaves and stems provide hiding spots for shrimp and fry, while floating growth creates shade that helps fish feel secure. It does not release harmful substances into the water.
Melting often happens when the plant transitions from emersed (grown above water) to submerged growth. Old leaves may die back, but new underwater leaves will appear once it adjusts. Stress from poor lighting, unstable water conditions, or lack of nutrients can also cause melting.
