The Marvel of Rotala Aquarium Plant

If you’re looking to add a touch of elegance to your aquarium, look no further than the Rotala indica. This beautiful plant is not only visually appealing but also easy to care for and beneficial to your tank’s health.

Species Overview

The Rotala indica, also known as the “Indian Toothcup,” is a stunning background plant that adds a touch of sophistication to any aquarium. It belongs to the Lythraceae family and is native to India and Southeast Asia. In the wild, it can grow both submerged and above the water’s surface, offering a versatile and unique growth pattern.

With its vertical orientation and delicate leaves, the Rotala indica is a fantastic choice for background decor. Whether you choose to grow it individually or in dense clumps, this plant is a sight to behold.

The Benefits of Having Rotala Indica in Your Tank

Beyond its aesthetic appeal, the Rotala indica provides numerous benefits to your freshwater tank. Like other live plants, it absorbs carbon dioxide and releases oxygen, improving the overall water conditions. Additionally, it helps eliminate harmful contaminants from fish waste, enriching the underwater environment and promoting healthy water conditions for your fish and other tank inhabitants.

But it’s not just improved water conditions that your fish will enjoy. The long, flowing stems of the Rotala indica provide a dense forest of vegetation, offering a safe and peaceful haven for shy creatures.

The Rotala indica is a dense plant known for its vertical growth. It features tall stems that reach towards the light, with delicate leaves sprouting horizontally. The leaves are typically round and concave, though some varieties have grass-like, pointed leaves.

Depending on the growing conditions, the plant can remain green or develop pinkish-red splashes towards the top of the stem. On rare occasions, a beautiful pink flower may bloom at the top of the stem, adding a touch of enchantment to your aquarium.

Size & Growth Rate

Rotala indica plants have a moderate growth rate, and under the right conditions, they can quickly climb to over a foot tall. In larger tanks and ponds, they may even reach up to two feet tall. However, it’s important to monitor their growth and regularly trim them to prevent them from overtaking your aquarium.

Rotala Indica Care

Caring for Rotala indica is a breeze, making it suitable for both beginner and experienced aquarists. Here are some essential care guidelines to ensure the plant thrives in your tank.

Tank Size

For optimal growth and stability, it is recommended to house Rotala indica in an aquarium that’s no smaller than 10 gallons. Larger tanks provide ample space for the plant to flourish and create impressive density.

Water Parameters

Rotala indica plants adapt well to a wide range of freshwater environments. They prefer standard tropical conditions, with a water temperature between 72°F to 82°F and pH levels ranging from 6.0 to 7.5. Regularly test the water parameters and keep them within the specified ranges to maintain a healthy environment for your fish.

Rotala indica plants are flexible when it comes to lighting. They require a standard day/night cycle and thrive with sufficient light. However, the amount of light provided will impact the plant’s growth. Less light exposure will keep the plant more compact, while higher light exposure will increase its growth rate.


A fine substrate like sand or specialty aquatic plant substrate is ideal for Rotala indica plants. The plant-focused substrate contains essential minerals and nutrients that promote growth. Ensure the substrate is at least two inches deep to allow the roots to spread and anchor the plant.

Planting Rotala Indica

Planting Rotala indica is a straightforward process, but it requires a delicate touch due to the plant’s vertical growth. Carefully embed the bottom of the stem into the substrate at a slight angle to provide stability. This will prevent the plant from easily dislodging and floating to the surface.

Trimming & Pruning

Regular trimming is essential to prevent overgrowth. The frequency of trimming depends on the plant’s growth rate, which is influenced by light and fertilizer. You can trim the plant back anytime it becomes too unruly. Simply use shears to snip off the top of the stem just above a node where two leaves emerge.

Tank Mates

Rotala indica plants thrive best with docile and easy-going fish as tank mates. Avoid pairing them with energetic species or known uprooters, as their delicate leaves can be easily damaged. Stick to slow-moving fish with flowing fins or smaller species that won’t cause harm.


Propagation of Rotala indica is simple and can be done after pruning. Cut off at least one inch of the stem, strip off any leaves, and implant it into the soil. With time, the freshly cut stem will develop roots and grow into a brand-new plant.
