Choosing the Right Aquarium Peace Lily

Introducing an aquarium peace lily to your fish tank can enhance its ambiance and contribute to a healthy ecosystem for your fish. However, selecting the right peace lily for your aquarium environment is crucial for the plant’s growth and your fish’s health.

Consider the following factors when choosing an aquarium peace lily:

Size of your tankChoose a peace lily whose roots and leaves won’t take up too much space in your tank.
Lighting requirementsPeace lilies require moderate to bright, indirect light to grow and thrive. Make sure your tank is positioned in a place that receives sufficient light or install a light source to supplement it.
Suitable water conditionsPeace lilies prefer freshwater with a slightly acidic to neutral pH and temperature between 68-82°F. Ensure your aquarium’s water parameters are within the recommended range for peace lilies to grow healthy roots and leaves.

Choosing the right aquarium peace lily is the first step toward creating a thriving and vibrant ecosystem in your fish tank.

Preparing the Fish Tank for the Peace Lily

Before introducing an aquarium peace lily to your fish tank, it is essential to prepare the tank adequately. Proper preparation ensures that your plant thrives and contributes to a healthy ecosystem for your aquatic pets. The following tips will help you create a suitable environment.

Clean the Tank

The fish tank should be clean before introducing the peace lily. Remove any dirt, debris or algae, and clean the tank walls, gravel, and the décor meticulously. This step ensures that the plant has a clean surface to thrive.

Check the Water Parameters

The peace lily thrives in slightly acidic to neutral water with pH ranging between 6.0 to 7.5. Ensure that your tank’s pH level and water hardness align with these specifications. Also, test the levels of nitrate and ammonia, keeping them at a safe level for the fish and plant.

Adjust the Lighting

Your peace lily needs sufficient light to grow well. You should ensure that the light set up of the fish tank complements the plant’s needs. The plant should have direct light for six to eight hours daily. Avoid placing the tank in direct sunlight, which causes green water and algal growth.

Add a Substrate

The aquarium peace lily needs a suitable substrate to provide support for the roots and allow them to grow well. Choose a substrate that suits the plant’s needs and the aquarium’s setup. Typically, you can use gravel, sand, or potting mix with a layer of gravel on top.

By following these tips, you can prepare your fish tank adequately for the addition of a peace lily. Remember that the plant’s success largely depends on a suitable environment, so ensure that you take the necessary preparation steps.

Planting the Aquarium Peace Lily

After ensuring your fish tank is ready, it’s time to plant your aquarium peace lily. Proper planting is crucial to the plant’s healthy growth and survival, so follow these steps carefully:

  1. Choose the right substrate: Start by selecting a suitable substrate for your peace lily. You can either use aquarium gravel or a special aquatic substrate. Both options work well, but make sure there is enough depth for the roots to anchor.
  2. Position the plant: Next, determine where you want to position your peace lily in the tank. Consider the lighting needs of the plant and the visual effect you want to achieve. Once you have decided, carefully lower the peace lily into the substrate and gently press it in, ensuring it stays upright.
  3. Maintain the right depth: The roots of an aquarium peace lily should remain submerged in the substrate but not buried too deeply. A depth of around 3-5 cm is ideal. If you’ve planted your peace lily too deeply, slowly remove some of the substrate until the appropriate depth is achieved.
  4. Water the plant: Finally, water the planted aquarium peace lily thoroughly. Be careful not to dislodge it from the substrate or stir up the substrate too much. The water should cover the roots, but the foliage should remain above water level.

With proper planting done, you’re now one step closer to enjoying a beautiful, thriving aquarium peace lily.

Lighting and Watering Needs

Providing appropriate lighting and watering conditions is essential for the healthy growth of your aquarium peace lily. These plants typically require low to moderate light levels, with indirect or filtered light being preferable to direct sun exposure. If your fish tank is in a dimly lit room, consider investing in a fluorescent or LED light to supplement your plant’s lighting needs.

When it comes to watering, it’s important to keep the soil moist without waterlogging it, as this can lead to rot and other issues. Aim to water your aquarium peace lily once a week, allowing the soil to dry out slightly between waterings. If your fish tank’s water parameters are not ideal for your plant, you may need to supplement with additional nutrients or adjust your filtration system to keep the water clean and healthy for both your fish and plant.

By providing adequate lighting and watering, you can ensure your aquarium peace lily thrives in your fish tank, adding to its aesthetic appeal and contributing to a healthy and balanced ecosystem.

Maintaining a Balanced Ecosystem

A balanced ecosystem in your fish tank is essential to ensure optimal health and growth for both your fish and aquarium peace lily. As the peace lily absorbs nutrients from the water, it helps to keep the water clean and oxygenated, reducing the risk of algae growth. To maintain a healthy ecosystem, follow these tips:

Maintain appropriate nutrient levels

The key to maintaining nutrient levels in your fish tank is to monitor your fish’s feeding patterns and avoid overfeeding. Excess food can quickly lead to a spike in ammonia and nitrate levels, which can be harmful to both the fish and the peace lily. Regular water changes can also help to keep nutrient levels stable.

Manage algae growth

Algae growth is a common problem in fish tanks, but it can be managed by maintaining proper lighting levels, avoiding excessive feeding, and regularly cleaning the tank and filters. You can also add algae-eating fish, such as snails or shrimp, to help keep the algae under control.

Ensure a harmonious coexistence

As a living plant, the aquarium peace lily requires a certain level of care and attention to thrive. Make sure to check its condition regularly and remove any dead or dying leaves promptly. You should also avoid placing the peace lily too close to the filter or pumps, which can cause excessive water movement and damage the plant.

Troubleshooting Common Issues

Even with the best care, your aquarium peace lily may experience common issues such as yellowing leaves, pests, and wilting. Don’t worry – we’ve got you covered! Below are some practical tips to help revive your peace lily:

Yellowing Leaves

If you notice yellowing leaves on your peace lily, it’s often a sign of overwatering or underwatering. To remedy this, check the water level in your tank and adjust accordingly. If the roots of your peace lily are sitting in water, they may become waterlogged and rot. On the other hand, if the roots are too dry, the leaves will begin to yellow and wilt. Ensure that you are maintaining proper watering and drainage.


Common pests that can affect your aquarium peace lily are mealybugs and spider mites. These pesky critters feed on the leaves and stems of your plant, causing damage and defoliation. To prevent and treat pest infestations, you can introduce natural predators like ladybugs or use neem oil as a deterrent. Be sure to follow the instructions carefully and avoid using chemical pesticides that may harm your fish.


Wilting peace lilies may be a sign of underwatering, extreme temperature changes, or lack of light. If the leaves and stems of your plant are drooping, but the root system is healthy, try readjusting its position in the aquarium to a spot with more light or move it away from direct heat sources. Additionally, be sure to monitor consistently the watering levels.

Enhancing Ambiance with an Aquarium Peace Lily

As discussed, aquarium peace lilies are a wonderful addition to any fish tank ecosystem. Not only do they provide biological benefits, but they also significantly enhance the visual appeal of your aquarium. With their vibrant green foliage and elegant white flowers, they can create a stunning focal point that adds a touch of natural elegance to any room.

Creating a Serene and Peaceful Atmosphere

The addition of an aquarium peace lily can instantly transform your fish tank into a serene and calming space. With its delicate and graceful form, the peace lily captures the eye and creates a sense of tranquility and peacefulness. Their calming influence can positively impact both you and your aquatic pets, making it an ideal plant choice for any aquarium.

The Perfect Complement to Your Fish Tank’s Aesthetic

Aquarium peace lilies come in a range of sizes, making them suitable for small or large tanks. Their lush foliage and beautiful blooms work well with a range of aquarium designs, from minimalist to elaborate. They are also ideal for creating a natural and authentic environment for your fish, which they can hide behind or swim through, adding to the aesthetic appeal of your tank.


Incorporating an aquarium peace lily into your fish tank is a great way to add beauty while maintaining a healthy ecosystem for your fish.
