🌿 Common Names

Spade-Leaf Anubias

🌍 Origin

Anubias gracilis is native to the tropical regions of West Africa, particularly in Sierra Leone and Guinea. It naturally grows along shaded riverbanks, marshes, and wetlands, thriving in warm, humid environments. Thanks to its robust nature and tolerance for low light, it is well-suited for both aquariums and high-humidity setups such as paludariums.

🌱 Growing Conditions

Anubias gracilis is a hardy, versatile plant that thrives both fully submerged in aquariums and emersed in humid environments like paludariums or pond edges. It prefers moderate lighting but adapts well to low-light conditions, making it a reliable choice for low-tech setups. This flexibility allows for varied placement without requiring high-intensity lighting.

With its slow growth rate, Anubias gracilis can reach up to 20–60 cm (7.87–23.62 inches) in height, making it ideal for background planting. It grows best under stable conditions with a pH range of 5.6–8 and water hardness between 5–18 dGH. Preferred temperature is 20–30 °C (68–86 °F). For optimal results, anchor the plant in fine gravel or attach it to rocks or driftwood, ensuring the rhizome remains above the substrate to prevent rot.

💡 Lighting Requirements

Anubias gracilis performs best under moderate light but can thrive in low-light conditions. In high-intensity lighting, algae may develop on the leaves, so placing the plant in partially shaded areas—such as beneath tall plants or décor—can help control buildup. A photoperiod of 8–10 hours daily supports healthy, consistent growth.

📍 Planting Area

Due to its height and upright structure, Anubias gracilis is best used in the background of aquariums, where it adds vertical dimension and lush greenery. It pairs well with driftwood, rocks, and decorative caves, creating a natural environment and offering cover for shy or nocturnal fish. Ensure the plant has sufficient space, as crowded conditions may hinder its development.

🔗 Propagation

Anubias gracilis is propagated through rhizome division. Cut a portion of the rhizome with several leaves attached, and secure it to rocks or driftwood using thread or aquatic glue. You may also lay it gently on the substrate surface. New shoots and roots will develop gradually. Avoid burying the rhizome, as this can lead to decay.

⚙️ Difficulty

This species is easy to care for, making it suitable for aquarists of all experience levels. Its ability to tolerate a broad range of conditions, combined with its slow growth, means it requires minimal pruning. Occasional fertilization supports overall health, and its thick, tough leaves deter most herbivorous fish, ensuring longevity in community setups.

📝 Short Description

Anubias gracilis, also known as Spade-Leaf Anubias, is a popular choice for background planting thanks to its tall, elegant, spade-shaped leaves and rich green tones. Its slow growth and low maintenance make it a favorite for aquariums seeking natural, long-lasting structure. While older leaves may gather some algae, this often enhances the plant’s natural appearance. In optimal conditions, it thrives in both submerged and emersed environments and may occasionally flower in humid setups. Always ensure the rhizome is securely anchored above the substrate to avoid disturbance or rot.

❓ Frequently Asked Questions (FAQ)

• 📏 How tall does Anubias gracilis grow?
  It can reach up to 60 cm (23.6 inches), making it an excellent background plant in larger aquariums.
• 💧 Can it grow fully submerged?
  ✅ Yes, it thrives both submerged in aquariums and emersed in paludariums or high-humidity environments.
• 💨 Does it need CO₂?
  Not required, but low-level CO₂ supplementation can help improve leaf color and overall vitality.
• 🌿 How do I attach it?
  Use plant-safe thread, rubber bands, or aquarium glue to attach the rhizome to rocks or driftwood. Avoid burying it in the substrate.
• 🐟 Is it safe with herbivorous fish?
  🛡️ Yes, its tough, leathery leaves are typically not appealing to plant-nibbling species like goldfish or cichlids.
• 🌞 What causes algae on its leaves?
  Too much direct light or poor water flow. Try placing it in shaded areas and maintain gentle current near the plant.
• ✂️ How often should I prune it?
  Rarely. Its slow growth rate means you may only need to trim damaged or aging leaves every few months.
