Common Names

Spade-Leaf Anubias

Origin

Anubias gracilis is native to the tropical regions of West Africa, especially in Sierra Leone and Guinea. It grows naturally along shaded riverbanks, marshes, and wetlands, thriving in warm and humid conditions. Its robust nature and tolerance for low light make it an excellent choice for aquariums and high-humidity setups like paludariums.

Growing Conditions

Anubias gracilis is a hardy and versatile plant that grows well fully submerged in aquariums or emersed in humid setups, such as paludariums or near pond edges. It prefers medium lighting but also adapts to low-light settings, making it suitable for low-tech aquariums. This adaptability allows flexible placement in the tank, without requiring intense light.

With its slow growth, Anubias gracilis reaches up to 20 - 60 cm (7.87 - 23.62 inches) in height, making it ideal for background placement. It prefers stable conditions with a pH range of 5.6 - 8 and water hardness between 5 - 18 dGH, with temperatures from 20 - 30 °C (68 - 86°F). For best results, place it in fine gravel or attach it to rocks or driftwood, ensuring the rhizome is above the substrate to prevent rot.

Lighting Requirements

Anubias gracilis thrives under medium lighting but adapts to low-light conditions. In bright light, watch for algae on leaves; placing it in shaded areas helps manage this. Its resilience in low light makes it ideal for shaded spots under taller plants or around hardscape. Aim for 8–10 hours of light daily for optimal growth.

Planting Area

Given its height and structure, Anubias gracilis is best placed in the background of aquariums, adding depth and lush greenery to the layout. This plant pairs well with rocks, driftwood, or caves, creating a natural look and offering hiding spots for shy fish. Avoid crowding it with other plants, as it needs space to reach its full height.

Propagation

Anubias gracilis propagates through rhizome division. Simply cut a piece of the rhizome with a few leaves and attach it to rocks or driftwood, or lay it gently on the substrate. The rhizome will anchor itself and produce new growth over time. Avoid burying the rhizome, as this may cause rotting.

Difficulty

This plant is easy to care for, making it suitable for beginners and experienced aquarists alike. Its tolerance for varied water conditions makes it adaptable. With its slow growth rate, Anubias gracilis needs minimal pruning, though occasional fertilization supports healthy growth. Its tough leaves deter herbivorous fish, making it a safe choice for tanks with plant-nibbling species.

Short Description

Anubias gracilis, also known as Spade-Leaf Anubias, is a popular background plant known for its tall, spade-shaped leaves and rich green color. Slow-growing and low-maintenance, it’s ideal for aquariums with minimal upkeep. Older leaves may attract algae, which can enhance its natural look. Once established, it thrives in both submerged and emersed settings, sometimes flowering in high-humidity conditions. Ensure the rhizome is anchored to a hard surface to prevent it from being moved by tank inhabitants.
