Species Summary

Rotala indica is a beautiful background plant belonging to the Lythraceae family. It is also known as Indian Toothcup and is native to India and Southeast Asia, where it grows both on land and in waterways. The thin and fragile leaves give it the perfect vertical orientation to make it an excellent choice for background decor.

The Benefits Of Having It In Your Tank

Beyond their eye-catching aesthetics, Rotala indica plants offer plenty of functional benefits too. The roots release valuable minerals, like carbon dioxide and ammonia, into the water column. This helps balance pH levels and keeps nitrate levels low. Additionally, oxygen is released into the surrounding water, which helps promote healthy gill activity in aquatic life.

Not only that, but Rotala indica also helps purify the environment, removing contaminants from the water. Plus, this species of foliage makes for excellent shelter for shy species of fish, which leads to a better quality of life for your finned inhabitants.


Rotala indica plants are made up of long, fleshy stems that continue to climb upwards as they mature. Long, fragile leaves sprout off the stem and grow horizontally, creating a dense clump of vegetation. Depending on the variety, they could have round or pointed leaves. Plus, if you’re lucky, you might even spy a pink flower blooming on the top part of its stem.

Size and Growth Rate

Rotala indica plants are moderately fast growers, reaching heights of a foot or more with ease. But, with the right adjustments, you can keep their growth rate reasonable too. They’re usually sold at nurseries and pet stores when they’re only a few inches tall.

It’s also important to note that these plants will quickly overrun your tank if you don’t trim them regularly. So, it’s best to monitor their growth and take action before they become too unruly.

Rotala Indica Care

Rotala indica care is relatively straightforward – luckily for all the beginner aquarists out there! All it needs is an aquarium that holds no less than 10 gallons, standard tropical conditions and occasional trimming.

Keeping the environment consistent will allow it to thrive and reach its true potential. For example, proper lighting will encourage new leaf growth and bolster its attractive coloration.

1. Light

Rotala Indica is a low to medium-light plant, and it is important to provide the right amount of light to ensure its health and longevity. Aim for a light intensity of around 0.5 watts per liter and ensure that the light is evenly distributed throughout the aquarium. If you find that the plant is not growing well or is turning yellow, this could be a sign that it is not getting enough light.


Promotes Healthy Growth: Adequate light is essential for the healthy growth of Rotala Indica. Providing the plant with the right amount of light will help it to grow tall, bushier, and produce more shoots.


Algae Growth: Too much light can lead to an increase in algae growth, which can be harmful to Rotala Indica and other aquatic life in the aquarium.

2. Substrate

Requires a nutrient-rich substrate in order to grow well. A substrate that is high in nutrients will help to encourage the plant to grow taller and bushier. You can achieve this by adding a layer of soil or using a special aquarium plant substrate. In addition, adding a layer of fertilizer to the substrate will also help to boost growth.


Improved Water Chemistry: The right type of substrate can improve water chemistry, making it more hospitable for Rotala Indica and other aquatic life in the aquarium.


Compatibility: Some types of a substrate may not be compatible with Rotala Indica or other aquatic life in the aquarium. It is important to choose a substrate that is appropriate for your particular setup.

3. CO2

Known to be particularly demanding in terms of CO2 supplementation. It is important to provide adequate CO2 supplementation in order to maintain a healthy aquarium. You can achieve this by adding a CO2 diffuser or by using a CO2 generator.


Enhances Color: CO2 supplementation can also enhance the color of Rotala Indica, making it even more vibrant and attractive in your aquarium.


Safety Concerns: CO2 systems can pose a safety risk if not handled properly, as CO2 can be toxic in high concentrations.

4. Water

Rotala Indica is a very hardy plant and is able to tolerate a wide range of water conditions. However, it is important to maintain a consistent pH and water temperature in order to ensure its health. Aim for a pH of around 7.0 and a temperature of around 22-26°C.


Supports Photosynthesis: Water also plays a role in photosynthesis, as it helps to transport nutrients and other essential substances to the plant’s cells.


Water Changes: Regular water changes are necessary to maintain the health of Rotala Indica and other aquatic life in the aquarium. This can be time-consuming and inconvenient.

5. Pruning

Regular pruning is an essential part of Rotala Indica care. Pruning will help to control the plant’s growth and prevent it from becoming too tall. In addition, it will also help to promote bushier growth and encourage the plant to produce more shoots.


Controls Size: Pruning also helps to control the size of Rotala Indica, allowing you to keep the plant compact and prevent it from overgrowing your aquarium.


Proper Technique: Pruning requires a proper technique to be effective and avoid damaging the plant. Improper pruning can harm Rotala Indica, leading to stunted growth or even death.
