TCulture Rotala Vietnam H'ra in pot 

1. Appearance: Rotala Vietnam H'ra features narrow, lanceolate leaves that are typically green or reddish-brown in color. The plant exhibits a compact growth pattern with numerous stems branching out from a central point. Under high lighting and nutrient-rich conditions, the upper parts of the plant can develop intense red, pink, or orange hues, which make it a visually striking addition to the aquarium.

2. Growth: This plant has a moderate growth rate and can reach a height of 4 to 6 inches (10 to 15 cm) in an aquarium. With regular pruning and maintenance, it can form dense bushes and create a lush appearance in the background or midground of the tank.

3. Lighting and CO2 Requirements: To achieve and maintain vibrant coloration and compact growth, Rotala Vietnam H'ra requires moderate to high lighting levels. Providing around 2 to 3 watts per gallon (or 0.5 to 0.8 watts per liter) of light is recommended. Additionally, supplying carbon dioxide (CO2) supplementation will further promote healthy growth and color development.

4. Water Parameters: The ideal water parameters for Rotala Vietnam H'ra are as follows:

   • Temperature: 72-82°F (22-28°C)
   • pH: 5.0-7.5
   • Hardness: Soft to moderately hard water (2-10 dKH)

5. Nutrient Requirements: Like most aquatic plants, Rotala Vietnam H'ra benefits from a nutrient-rich environment. Regular dosing of essential macronutrients (nitrogen, phosphorus, and potassium) and micronutrients (iron, magnesium, etc.) through liquid fertilizers or root tabs can support its growth and coloration. Ensuring a balanced nutrient regimen will help prevent nutrient deficiencies or imbalances.

6. Placement and Propagation: Rotala Vietnam H'ra is commonly used as a background or midground plant in aquariums. Its compact growth habit makes it suitable for creating dense groupings or as a filler plant in aquascapes. Propagation can be achieved by taking stem cuttings and replanting them in the substrate. The cuttings will develop roots and continue to grow, gradually forming a thick cluster of plants.
