Overview

Sagittaria subulata, commonly known as Dwarf Sagittaria, is a versatile and attractive foreground plant that resembles grass with its thin, green leaves. This plant is perfect for creating a natural, carpeted look in an aquarium, providing excellent ground cover that enhances the overall aesthetic of the tank.

Position in Aquarium

  • Location: Used to create a natural edge along the front of the middle section, transitioning smoothly to the foreground.
  • Grouping: Plant densely to achieve a lush, carpet-like appearance that visually and physically bridges the foreground and midground areas.

Care Requirements

Lighting

  • Intensity: Medium to high
  • Duration: 10-12 hours per day to promote dense growth and prevent elongation of leaves.

Water Conditions

  • Temperature: 20-26°C (68-79°F)
  • pH: 6.0-7.5
  • Hardness: Soft to moderately hard, 3-12 dKH

Substrate

  • Type: Prefers a fine, nutrient-rich substrate to support rapid root development and growth.

CO2

  • Addition: Beneficial for promoting faster growth and denser carpet formation.
  • Rate: 10-20 mg/L

Fertilization

  • Macro Nutrients: Regular supplementation is important, especially in planted tanks with high lighting and CO2.
  • Micro Nutrients: Regular dosing with trace elements, including iron, helps maintain vigorous growth and vibrant green color.

Pruning and Maintenance

  • Pruning Frequency: Moderate; trim back as needed to control spread and maintain the desired carpet thickness.
  • Trimming Technique: Cut leaves at the base to encourage new growth from the roots.

Propagation

  • Method: Spreads easily by sending out runners that form new plants. These can be detached and replanted as needed to fill in gaps or expand the carpet.
  • Growth Rate: Fast under optimal conditions, quickly filling in the designated area.

Common Issues

  • Thinning: Can occur in areas with inadequate lighting or insufficient nutrients.
  • Algae Growth: Leaves can become a substrate for algae if nutrient levels are unbalanced or lighting is excessive without corresponding CO2.

Additional Tips

  • Planting Depth: Ensure that the crowns of the plants are not buried too deeply in the substrate to avoid rot.
  • Spatial Management: Regularly manage the spread of runners to maintain a neat and defined carpet area, especially near the front glass for clear viewing.
