Rotala Colorata

Rotala colorata is a striking aquatic plant species known for its vibrant reddish-pink coloration. It belongs to the genus Rotala within the family Lythraceae and is native to Southeast Asia, particularly regions like Thailand and Malaysia.

This plant is popular among aquarium enthusiasts due to its attractive appearance and relatively easy maintenance compared to some other aquatic plants. However, it does require proper care and specific conditions to thrive.

Here are some key points about Rotala colorata:

1. Appearance: Rotala colorata typically has narrow, lance-shaped leaves that grow in dense clusters along the stem. The foliage ranges in color from green to reddish-pink, with the intensity of the coloration influenced by factors such as lighting, nutrient levels, and CO2 availability.

2. Lighting and CO2: Adequate lighting and carbon dioxide (CO2) supplementation are essential for promoting vibrant growth and maintaining the red coloration of Rotala colorata. High-intensity lighting, such as LED lights designed for planted aquariums, can help stimulate photosynthesis and enhance coloration. CO2 injection or liquid carbon supplements can also be beneficial, as carbon is a crucial element for plant growth.

3. Water Parameters: Rotala colorata thrives in soft to moderately hard water with a slightly acidic to neutral pH range (around 6.0-7.5). Additionally, providing a nutrient-rich substrate and regular fertilization with micronutrients and macronutrients (such as nitrogen, phosphorus, and potassium) can support healthy growth and vibrant coloration.

4. Propagation: Like many stem plants, Rotala colorata can be propagated by taking stem cuttings and replanting them in the substrate. With proper care, these cuttings will develop roots and grow into new plants. Regular pruning can also help maintain the desired shape and density of the plant.

5. Placement: In an aquarium, Rotala colorata can be used as a midground or background plant, depending on its size and growth habit. When planted in groups or clusters, it creates a visually striking focal point and adds depth to the aquascape.

6. Temperature: This plant generally prefers tropical temperatures ranging from 22°C to 28°C (72°F to 82°F), although it can tolerate slightly cooler or warmer conditions within this range.

Overall, Rotala colorata is a beautiful and rewarding plant species to cultivate in a planted aquarium, adding vibrant color and natural beauty to the aquatic environment. However, it's important to provide the proper care and conditions it requires to thrive.
