Origin

Rotala indica, commonly known as Indian Toothcap, is native to wetlands and rice paddies in Southeast Asia, particularly India. It was first described by the German botanist Bernhard Adalbert Emil Koehne in 1881 and has since gained popularity in aquascaping and aquarium settings across various countries, including the United States and parts of Europe15.

Light Conditions

Rotala indica thrives best under moderate to high light conditions. Adequate lighting is crucial for the plant to develop its characteristic reddish hues at the top of its stems. Insufficient light may lead to leggy growth and poor coloration23.

Water Conditions

This aquatic plant is adaptable to a range of water conditions. It prefers slightly acidic to neutral pH levels (around 6.0 to 7.5) and can tolerate a variety of hardness levels. Regular water changes and good filtration are recommended to maintain optimal health16.

Planting Rotala Indica

Planting Steps

1. Preparation: Before planting, allow the Rotala indica to acclimate in your aquarium environment for a few hours.
2. Substrate Choice: Use a nutrient-rich substrate that can be finely granulated gravel or sand.
3. Spacing: When planting, space individual stems about 2 centimeters apart to allow for growth and to prevent overcrowding.
4. Planting Technique: Gently insert the stems into the substrate, ensuring that they are secure but not buried too deeply, which could hinder their growth.
5. Maintenance: Regular trimming is necessary to encourage bushy growth and prevent the lower leaves from becoming shaded136.

• By following these guidelines, Rotala indica can flourish in your aquarium, providing aesthetic beauty with its vibrant green leaves and delicate pink flowers while also contributing to a healthy aquatic ecosystem.
