Subwassertang (Lomariopsis lineata)

Subwassertang is hands down one of the best plants for shrimp tanks. With its lush green color and soft texture, it adds a natural and visually appealing element to your aquascape. This slow-growing plant/moss forms a beautiful bush-like structure over time, providing shrimp with ample feeding surfaces, hiding spaces, and playful areas—perfect for both adults and baby shrimp.

Key Features:

• Growth Habit: Forms a natural bush over time once established and rooted.
• Shrimp Benefits:
  • Excellent for shrimp grazing due to biofilm and microorganisms on its surface.
  • Provides hiding spots, especially valuable for baby shrimp.
  • Encourages natural behaviors like foraging and playing.
• Aesthetic Appeal: Enhances tank visuals with its vibrant, lush green hue.

Other Common Names:

• Süsswassertang
• Süßwassertang
• Round Pellia
• False Round Pellia

Preferred Conditions:

• Temperature: Prefers slightly cooler water; ideal range is 20–23°C (68–73°F).
• Water Hardness: Thrives in soft to moderately hard water.
• Light Requirements:
  • Low to medium light is sufficient.
  • Higher light levels encourage faster growth but may increase the risk of algae.
• CO₂: Not necessary; avoid liquid carbon additives like Scape Liquid Carbon or Seachem Excel, as they can harm the plant.

Care Tips:

1. Placement: Subwassertang does not root into the substrate but can be attached to rocks, driftwood, or simply left free-floating.
2. Cleaning: Gently rinse or swish in tank water to remove debris.
3. Trimming: Trim as needed to maintain shape and prevent overgrowth.
4. Avoid Chemicals: Refrain from using liquid carbon products, as Subwassertang is sensitive to these additives.

Tank and Growth Notes:

• Origin: Grown in tanks with shrimp, so it may occasionally contain Ramshorn Snails or snail eggs. These snails are harmless and contribute to a balanced ecosystem.
• Growth Rate: Slow to moderate, depending on light and water conditions.
• Propagation: Break off a portion and place it elsewhere in the tank; it will gradually establish itself.

Subwassertang is not only a practical choice for shrimp tanks but also a visually stunning one. Its delicate appearance, low-maintenance nature, and benefits for shrimp make it a must-have plant for aquarists of all experience levels. Whether you’re creating a dedicated shrimp setup or enhancing a planted tank, Subwassertang will quickly become a favorite addition.
