1. Transitioning and Establishing

During this transitioning period, you might notice that some of the older leaves start to fall off. But don’t worry, this is completely normal. It’s just their way of adapting to the new water conditions. Sometimes, people think this is melting, but it’s not. It’s just a natural part of the adjustment process.

To help these plants settle in and thrive, it’s important to be patient and provide consistent care for your tank. Don’t get worried if you see some changes at first. Give them the time and support they need, and soon you’ll see new growth and healthy leaves showing up.

2. Physical Damage

Physical damage to your aquarium plants can happen in a lively tank with active fish or aggressive tankmates. Sometimes, these playful fish might unintentionally damage the leaves by biting, nibbling, or uprooting them, which can make it seem like the leaves are melting.

To keep your plants safe from such interactions, you can create shelters or separate the more delicate plants from the more energetic fish. Adding rocks, driftwood, or artificial structures in the tank provides hiding spots where your plants can take cover and avoid getting harmed.

3. Nutrient Deficiencies

Just like how we need a balanced diet with all the necessary vitamins and minerals to stay healthy, aquatic plants also need essential nutrients to grow strong and vibrant. These vital elements include nitrogen, phosphorus, potassium, iron, and trace minerals.

If your plants don’t get enough of these important nutrients, they might show signs of distress, like their leaves starting to melt or deteriorate. But don’t worry! There’s an easy solution to help them recover and thrive again.

You can give your plants a special treat in the form of a comprehensive liquid fertilizer or root tabs. These are like special plant foods packed with all the nutrients your plants need to rejuvenate and grow beautifully.

4. General Poor Growth Conditions

The growth of your aquarium plants depends a lot on how well your whole aquarium is doing. If the water quality is not good, it can affect your plants too.

Things like high ammonia or nitrate levels, not having enough filtration, or not doing regular water changes can all lead to problems with your plants.

To make sure your plants grow well, you need to create a clean and stable environment for your aquarium. This means keeping the water quality in check and making sure the levels of harmful substances like ammonia and nitrate are low.

Having a good filtration system is also essential. It helps keep the water clean and clear, which is excellent for your plants and all the other creatures in your tank. Regular water changes are crucial too. It’s like giving your aquarium a fresh breath of air. 

5. Lack of Light

Light is incredibly important for your aquarium plants because it’s how they make their food. Just like we need food for energy, plants need light to produce the energy they need to grow and stay healthy.

If your plants don’t get enough light, they can become weak and start losing their leaves. It’s like when we don’t get enough nutrients, we might feel tired and unwell. The same thing happens to plants without enough light.

To help your plants grow strong and vibrant, invest in good-quality aquarium lights that match the needs of your specific plant species. Different plants have different light requirements, so it’s essential to provide the right kind of light for them.

6. Environmental Change

Changes in the environment can affect the aquatic plants in your aquarium. When there are sudden shifts in things like the water temperature or pH level, it can stress out the plants, and they might start shedding leaves.

To keep your plants happy and healthy, it’s essential to introduce any changes slowly. Give them time to adjust to the new conditions little by little. It’s like helping them get used to a new home at their own pace.

Also, try to maintain stability in the water conditions as much as possible. Fluctuations can make it tough for your plants to thrive. By keeping things steady, you’re providing a more comfortable and stable environment for your green buddies.

7. Ammonia Burn

Ammonia is a dangerous chemical that can be found in your aquarium. It comes from fish waste and when things in the tank start to decay.

If there’s too much ammonia in the water, it can harm your plant leaves, and they might look like they’re melting.

To keep your plants safe, test the water regularly. This way, you can check if the ammonia levels are okay. If you notice it’s getting too high, you need to take action to get rid of it.

One of the best ways to prevent ammonia buildup is to manage waste properly. Cleaning the tank regularly and removing any decaying matter helps to keep the ammonia levels under control.

By keeping an eye on ammonia levels and taking good care of your aquarium, you’ll help your plants grow healthy and beautiful. It’s like making sure the air we breathe is clean and safe for us. 

8. Algae Overgrowth

Having too much algae in your aquarium can cause trouble for your aquatic plants. Algae can grow too much and cover your plants, blocking them from getting enough light and nutrients they need to grow well.

To keep the algae in check and help your plants flourish, you need to find the right balance. Make sure your plants have enough nutrients, light, and carbon dioxide to grow happily.

Your plants will have the space they need to grow beautifully, and you’ll have a clean and attractive underwater world to enjoy. It’s like creating a happy home for your green friends, where they can thrive and shine.

Now that you understand why your aquatic plants melt, let’s explore whether the melting process is typical and unavoidable in new tanks.

Is the process of melting typical and inevitable in new tanks?

If you notice your aquarium plants looking a bit droopy or losing some leaves when you first set up a new tank, don’t worry, it’s completely normal. When plants are moved to a new home, they need time to get used to their surroundings. 

During this adjustment period, they might drop some of their older leaves. But don’t be alarmed; this is just their way of preparing to grow new and healthier leaves.

The reason they do this is because they are focusing their energy on growing strong roots and adapting to the new water conditions in the tank. It’s like they’re getting settled in and making themselves comfortable.

As they get more used to their new home, they will start to grow fresh and colorful leaves that will thrive in the specific conditions you’ve created for them.

So, don’t be too concerned if you see some changes in your plants at first. It’s all part of a natural process, and it’s a sign that your plants are adjusting and getting ready to show off their beauty.

With a little love and care, you’ll soon see your plants flourishing, bringing life and charm to your aquarium. Just be patient and enjoy the lovely transformation happening in your underwater garden.

What do I do if I already have melting plants?

It’s normal for plants to go through a rough patch sometimes. The first thing to do is to be patient because it takes time for them to recover. Start by checking the water conditions in your tank. 

Make sure the temperature, pH, and other levels are right for the specific plants you have. If needed, make adjustments to create a comfortable environment for your plants to grow happily.

Give your plants a little help by using some fertilizer. Just like we need nutrients to stay healthy, plants also need their share of vitamins. Look for a good quality liquid fertilizer and use it according to the instructions.

Pay attention to the lighting too. Make sure your aquarium gets the right amount of light for your plants. Too little or too much light can stress them out, so finding the right balance is important.

To assist your plants in recovering, gently trim away the decaying leaves. Not only does this keep your tank looking tidy, but it also prevents any potential diseases from spreading to other plants.

Remember, your plants are living beings, and they deserve proper care like any other pet. With a little attention and effort, you can help them thrive again and bring life and beauty back to your aquarium. 


In conclusion, this blog post has explored the troubling issue of aquarium enthusiasts facing the perplexing melting of their once vibrant aquatic plants. We understand the frustration and confusion it can bring, leading hobbyists to seek solutions. 

Healthy plants are vital for creating a natural paradise in a well-maintained aquarium. We’ve discussed the reasons behind plant melting, especially in new tanks, and whether it’s normal. 

Additionally, valuable tips were provided to address the issue of wilting plants. Remember, with patience and the right approach, you can revive your underwater world and create a flourishing aquatic ecosystem for all its inhabitants.


1. Is it possible for plants to recover from melting?

Yes, it is entirely possible for plants to recover from melting. In many cases, the melting process is a natural response to changes in the aquarium environment, such as when you first set up a new tank or when there’s a shift in water conditions.

As long as the underlying cause is addressed promptly, and the plant’s root system remains healthy, the plant can bounce back and start growing new leaves.

2. Is it necessary to trim melting plants?

Trimming melting plant leaves can be beneficial, especially if the melting is extensive or if the leaves have become unsightly.

By removing the decaying or dead parts, you allow the plant to concentrate its energy on new growth. Just make sure to use clean and sharp scissors to avoid injuring the healthy parts of the plant.

3. What are the signs of dying aquarium plants?

The signs of dying aquarium plants can vary depending on the plant species and the underlying issue.

However, some common indicators include yellowing or browning of leaves, excessive wilting, stunted growth, and the presence of rot or fungus on the plant.

It’s essential to identify the problem early and take appropriate action to save the plant and prevent further damage.

4. What are the causes of anubias melting?

Anubias melting can occur due to various factors, but the most common reasons are often related to changes in water parameters, lighting, or planting depth.

Anubias plants are sensitive to sudden shifts in their environment, and poor water quality, inadequate lighting, or burying the rhizome too deep in the substrate can lead to melting.

Maintaining stable water conditions and ensuring the proper placement of the plant can help prevent this issue.
