Bucephalandra Kotetsu

The Iron Blade Buce

What Is Bucephalandra ‘Kotetsu’?

Bucephalandra ‘Kotetsu’ is a rare and highly valued Bucephalandra known for its dark, metallic-toned leaves and strong, compact form. The name “Kotetsu,” which means “steel” or “iron” in Japanese, reflects its firm leaf structure and deep, powerful coloration.

Native to Borneo, Bucephalandra naturally grows attached to rocks and driftwood along fast-flowing jungle streams. ‘Kotetsu’ is a true aquatic plant that can grow fully submerged in aquariums or emersed in high-humidity environments.

Its leaves often show deep green to nearly black tones with a subtle metallic sheen under proper lighting, giving it a bold and refined look.

Strong and elegant, Bucephalandra ‘Kotetsu’ is ideal for aquarists who appreciate dark foliage with a structured presence.

How It Grows

This plant grows from a creeping rhizome that attaches firmly to rocks or driftwood. It spreads slowly and forms dense, compact clusters.

Growth is slow under stable aquarium conditions.

The Leaves

The leaves are thick and firm.

• Color: dark green to nearly black

• Surface: smooth with subtle metallic sheen

• Shape: oval to slightly elongated

The dark, steel-like tone is its main feature.

Light Needs

Prefers low to medium light.

• Moderate light enhances leaf sheen

• Avoid very strong lighting to reduce algae growth

Stable lighting helps maintain deep coloration.

Water & Aquarium Conditions

• Attach to rock or driftwood

• Do not bury the rhizome

• Thrives in clean, well-circulated water

• CO₂ is optional but supports better growth

• Ideal temperature: 22–28°C

Stable parameters are important for healthy development.

Growing Environment

Best suited for:

• Freshwater aquariums

• Nano tanks

• Contrast-focused aquascapes

• Paludariums (emersed form)

Care Level

Low to medium care.

• Suitable for beginners

• Slow-growing and easy to manage

• Minimal trimming required

Handling Note

Keep the rhizome above the substrate to prevent rot. Once attached and stable, Bucephalandra ‘Kotetsu’ will grow steadily and maintain its deep, metallic foliage.
