Preparing Your Aquarium

Follow these steps to prepare your aquarium for Anubias planting:

1. Clean the tank: If you’re working with an existing setup, perform a partial water change and clean the gravel to remove debris.
2. Check water parameters: Ensure your water conditions are suitable for Anubias. Ideal parameters are:
   • Temperature: 72-82°F (22-28°C)
   • pH: 6.0-7.5
   • Water hardness: 3-8 dKH
3. Prepare the gravel: If using new gravel, rinse it thoroughly to remove dust and debris. For an existing tank, gently stir the gravel to release trapped waste, then siphon it out.
4. Plan your layout: Decide where you want to place your Anubias plants. Consider factors like lighting, water flow, and the overall aesthetic of your aquascape.
5. Adjust lighting: Ensure your aquarium lighting is appropriate for Anubias. While they can tolerate low light, moderate lighting (10-20 lumens per liter) will promote healthier growth.

Preparing the Anubias Plants

Before planting, take these steps to prepare your Anubias:

1. Inspect the plants: Check for any signs of disease, pests, or damage. Healthy Anubias should have firm, green leaves and a solid rhizome.
2. Quarantine (optional): If introducing new plants to an established tank, consider quarantining them for 2-3 weeks to prevent the introduction of pests or diseases.
3. Trim if necessary: Remove any yellow or damaged leaves. If the roots are excessively long, you can trim them to about 1-2 inches.
4. Separate rhizomes (if applicable): If you have a large Anubias plant, you can divide the rhizome into smaller sections, ensuring each piece has at least 3-4 leaves.

Step-by-Step Guide to Planting Anubias in Gravel

Now that you’ve prepared your aquarium and plants, it’s time to start the planting process. Follow these steps carefully to ensure your Anubias is properly planted and set up for success.

Step 1: Create a Depression in the Gravel

Using your fingers or aquascaping tweezers, create a small depression in the gravel where you want to plant your Anubias. The depression should be deep enough to accommodate the roots but shallow enough to keep the rhizome above the substrate.

Step 2: Position the Anubias

Gently place the Anubias into the depression you’ve created. The most critical aspect of this step is ensuring that the rhizome remains above the gravel. The rhizome is the thick, horizontal stem from which the leaves and roots grow. Burying the rhizome can lead to rot and eventually kill the plant.

Step 3: Anchor the Roots

Carefully cover the roots with gravel, leaving the rhizome exposed. Use your tweezers to gently push gravel around the roots, providing stability to the plant. Be careful not to damage the delicate roots during this process.

Step 4: Secure the Plant

For additional stability, especially in tanks with strong water currents, you can use plant weights or thin, inert fishing line to secure the Anubias to a small, flat stone placed on top of the gravel. This temporary measure will help the plant establish itself.

Step 5: Adjust and Fine-tune

Once the plant is in place, make any necessary adjustments to its position. Ensure that the leaves are oriented in a way that looks natural and allows for proper water flow around the plant.

Step 6: Repeat for Additional Plants

If you’re planting multiple Anubias, repeat the process for each plant. Remember to space them appropriately, considering their potential growth and the overall aesthetic of your aquascape.

Step 7: Perform a Water Change

After planting, perform a partial water change (about 25-30% of the tank volume) to remove any debris stirred up during the planting process. Use a water conditioner to treat the new water before adding it to the tank.

Care and Maintenance After Planting

Once your Anubias is planted, proper care and maintenance will ensure its long-term health and growth. Here are some essential tips to keep your Anubias thriving:

Lighting

While Anubias can tolerate low light conditions, moderate lighting will promote healthier growth and more vibrant leaves. Aim for 10-20 lumens per liter, or 8-10 hours of light per day. Avoid intense direct light, which can lead to algae growth on the slow-growing Anubias leaves.

Fertilization

Anubias are not heavy feeders, but they can benefit from regular, light fertilization. Use a liquid fertilizer formulated for aquarium plants, following the manufacturer’s instructions for dosage. typically, fertilizing once a week or every other week is sufficient.

Water Parameters

Maintain stable water parameters to support your Anubias:

• Temperature: 72-82°F (22-28°C)
• pH: 6.0-7.5
• Water hardness: 3-8 dKH

Regular water testing and partial water changes (10-20% weekly) will help maintain these parameters.

Pruning and Maintenance

Anubias are slow-growing plants that require minimal pruning. However, you should:

1. Remove any yellow or damaged leaves to maintain plant health and appearance.
2. Trim roots if they become excessively long and start to float.
3. Control algae growth by gently wiping leaves with a soft cloth or sponge during water changes.

Propagation

As your Anubias grows, you can propagate it to create new plants:

1. Identify a healthy section of the rhizome with at least 3-4 leaves.
2. Using clean, sharp scissors, cut the rhizome, ensuring each section has some roots.
3. Plant the new sections following the same method described earlier.

Common Issues and Troubleshooting

Even with proper care, you may encounter some issues with your Anubias. Here are some common problems and their solutions:

Yellowing Leaves

Cause: Nutrient deficiency, old age, or insufficient light. Solution: Check your fertilization routine, ensure proper lighting, and remove old leaves to encourage new growth.

Rhizome Rot

Cause: Rhizome buried in substrate or poor water quality. Solution: Ensure the rhizome is above the gravel and improve water quality through regular maintenance.

Slow Growth

Cause: Natural characteristic of Anubias, but can be exacerbated by poor conditions. Solution: Be patient, ensure proper nutrition, lighting, and water parameters. Growth of 1-3 new leaves per month is normal.

Algae Growth on Leaves

Cause: Excessive light or nutrients in the water. Solution: Reduce lighting duration or intensity, balance fertilization, and manually remove algae during water changes.

Floating Plants

Cause: Insufficient anchoring or fish disturbance. Solution: Reposition the plant, ensuring roots are well-covered with gravel, or temporarily anchor with weights or fishing line.
