What is Anubias Hastifolia?
Anubias hastifolia is a species of aquatic plant in the Araceae family, native to Africa. Like other plants in the Anubias genus, it is a slow-growing and hardy species that thrives in low-light environments, making it a perfect choice for both beginner and advanced aquarists.
Anubias hastifolia is particularly admired for its unique, lance-shaped leaves, which give it a distinct appearance compared to other Anubias species. The leaves are dark green with a glossy finish, and they can grow up to 12 inches (30 cm) in length, making it an excellent choice for background or mid-ground placement in aquariums.
Due to its resilience and adaptability, Anubias hastifolia is often used in aquascaping, including low-tech setups, paludariums, and biotope tanks. It is also highly regarded for its ability to thrive in both submerged and emerged conditions, although in aquariums, it is typically grown underwater.
Physical Description of Anubias Hastifolia
Anubias hastifolia has several notable features that make it a popular choice in aquarium hobbyist circles:
- Leaves: The long, lance-shaped leaves are dark green and can reach up to 12 inches (30 cm) in length, with sharp, pointed tips. The leaves have a leathery texture and a glossy sheen that adds depth and beauty to the aquascape.
- Rhizomes: Like other Anubias plants, Anubias hastifolia grows from a rhizome (underground stem), and this rhizome should not be buried in the substrate. Instead, it should be attached to rocks, driftwood, or other hard surfaces. The rhizome spreads horizontally, producing new leaves and roots over time.
- Growth Habit: Anubias hastifolia is a slow-growing plant. It produces new leaves from its rhizome and sends out roots that anchor it to hard surfaces. Because of its growth habit, Anubias hastifolia is best suited for mid-ground to background placement in your aquarium.
- Flowers: In emergent conditions, Anubias hastifolia produces small white flowers on a long stalk, though flowering is rare in submerged conditions.
Ideal Water Conditions for Anubias Hastifolia
Anubias hastifolia is a hardy plant that can tolerate a variety of water conditions, making it ideal for different types of aquariums. However, to ensure the plant thrives, it's important to replicate its natural habitat as closely as possible. Here are the ideal water parameters for this plant:
1. Water Temperature
Anubias hastifolia prefers a tropical temperature range, similar to many aquarium plants. The ideal water temperature for this plant is between 72°F to 82°F (22°C to 28°C). Keeping the temperature consistent within this range promotes healthy growth and vibrant foliage. This temperature range is also conducive to the health of your fish and other aquatic inhabitants.
2. pH Level
This plant is adaptable to a wide range of pH levels, but it grows best in neutral to slightly acidic water. The ideal pH range for Anubias hastifolia is between 6.5 to 7.5. While it can tolerate slightly higher or lower pH, maintaining it within this range will ensure the plant absorbs nutrients efficiently and avoids stress.
3. Water Hardness
Anubias hastifolia prefers moderately soft to hard water. A general range of 4-15 dGH (degrees of general hardness) is ideal for this plant. Soft water may slow its growth slightly, while harder water can promote faster growth, though excessive hardness can lead to nutrient imbalances. Keep an eye on water hardness to ensure the plant is receiving adequate minerals.
4. Water Flow
Anubias hastifolia is not a fan of strong currents and prefers calm, low-flow water. While it can adapt to moderate water movement, excessive flow can damage its delicate leaves. In an aquarium, ensure the plant is placed in an area with gentle water circulation.
Lighting Requirements for Anubias Hastifolia
Anubias hastifolia is a low-light plant, making it perfect for low-tech aquariums or setups where other high-maintenance plants may struggle. However, it still needs a minimum amount of light to grow effectively. Here are the lighting requirements for this plant:
1. Light Intensity
Anubias hastifolia thrives under low to moderate lighting. It doesn’t require intense light, which makes it ideal for aquariums with low-tech setups or low-light tanks. In fact, too much light can lead to algae growth or stunted growth of the plant. If you're using LED lighting, aim for 10-15 lumens per liter of water.
2. Light Duration
To encourage healthy growth without promoting excessive algae, it’s recommended to provide 6-8 hours of light per day for Anubias hastifolia. If you provide too much light, algae can develop on the leaves, while too little light can cause the plant to become leggy and weak.
3. Light Spectrum
Anubias hastifolia benefits from a full-spectrum light that closely mimics natural sunlight. A color temperature between 6,500K and 7,500K is ideal for this plant. This spectrum provides the right balance of light for photosynthesis and helps the plant maintain a healthy green color.
Substrate Requirements for Anubias Hastifolia
Unlike many aquarium plants, Anubias hastifolia doesn’t require soil or nutrient-rich substrate to thrive. In fact, its rhizome should not be buried in the substrate. Instead, it should be attached to hard surfaces like rocks, driftwood, or aquascaping decorations. Here's what you need to know about substrate options:
1. Substrate Type
While you don't need to bury the plant’s rhizome in the substrate, a nutrient-rich substrate can help promote healthy root development. If you're using gravel, sand, or aquarium soil, it's okay, but make sure you provide the plant with external nutrients via root tabs or liquid fertilizers to keep it healthy.
2. Planting Tips
To plant Anubias hastifolia, secure its rhizome to a rock or driftwood using fishing line, plant glue, or rubber bands. Once the rhizome is securely attached, the plant will naturally send out new roots to anchor itself. Avoid burying the rhizome, as this can lead to rot and damage the plant.
Fertilization and Nutrient Requirements
Although Anubias hastifolia is relatively low-maintenance in terms of nutrients, it does benefit from regular fertilization. Since it grows slowly, it doesn’t require as much fertilizer as some faster-growing species, but providing the right nutrients will help maintain its health and vibrancy.
1. Root Fertilizers
If you're using a substrate without nutrients, consider adding root tabs around the base of the plant. These slow-release fertilizers provide Anubias hastifolia with essential minerals like iron, potassium, and trace elements, which it can absorb through its roots.
2. Liquid Fertilizers
In addition to root tabs, using a liquid fertilizer can help provide the plant with necessary nutrients for leaf development. Choose a balanced fertilizer that includes all macronutrients (nitrogen, phosphorus, potassium) and micronutrients (iron, magnesium, calcium) to ensure overall plant health.
3. CO2 Supplementation
While Anubias hastifolia does not require CO2 supplementation, adding it to the aquarium can accelerate its growth. If you are running a high-tech tank or one with high light intensity, providing CO2 can help Anubias hastifolia grow more vigorously and prevent it from becoming leggy.
Common Problems and Troubleshooting
Despite its hardy nature, Anubias hastifolia may encounter a few common issues that require attention. Here's how to handle them:
1. Yellowing Leaves
If the leaves of Anubias hastifolia are turning yellow, this is often a sign of nutrient deficiency, particularly nitrogen or iron. Regular fertilization and using root tabs can help resolve this issue.
2. Algae Growth
Anubias hastifolia is prone to algae growth, especially under high lighting conditions. To prevent this, make sure you are not providing excessive light, and consider adding snails or shrimp that can help clean the leaves.
3. Rotting Rhizome
If the rhizome of Anubias hastifolia begins to rot, it is likely because it has been buried in the substrate. Always ensure that the rhizome is attached to a hard surface and not submerged in the substrate. If rot occurs, remove the affected portion and replant the healthy rhizome.
Tank Mates and Aquascaping Ideas
Anubias hastifolia is a peaceful plant that works well with a variety of tank mates. Here’s how to integrate it into your aquascaping design:
1. Tank Mates
Anubias hastifolia is compatible with peaceful fish like Tetras, Guppies, Corydoras, and Betta fish. It also does well in shrimp tanks with Amano shrimp or Cherry shrimp, which help keep the plant free from algae. Avoid placing the plant in tanks with species that might uproot or damage it, such as Cichlids.
2. Aquascaping
Anubias hastifolia is an excellent choice for mid-ground or background placement due to its upright growth habit. Pair it with other plants like Java Fern, Cryptocoryne, or Anubias barteri for a beautiful, natural aquascape. You can also attach it to driftwood or rocks for a more natural and organic look.
