- Plant Type: Rooted rosette plant
- Placement: Background or midground
- Light Requirement: Moderate to high
- CO2 Needed: Optional, but improves growth
- Growth Rate: Moderate
- Temperature: 72–82°F (22–28°C)
Why Choose Amazon Sword?
- Hardy and beginner-friendly
- Grows large, making it ideal for backgrounds
- Helps oxygenate the water
- Absorbs excess nutrients (especially with root tabs)
- Fish like to hide behind its broad leaves

Tank Setup for Amazon Sword
Tank Size
Amazon Swords grow large—up to 20 inches tall, so they’re best suited for:
- 20+ gallon tanks
- Tall tanks for full leaf extension
- Background placement in large aquascapes
Water Parameters
| Parameter | Ideal Range |
| Temperature | 72–82°F (22–28°C) |
| pH | 6.5–7.5 |
| Hardness | Soft to moderately hard water |
Lighting Requirements
Amazon Swords need moderate to strong lighting for healthy, vibrant growth:
- 8–10 hours of full-spectrum light per day
- LED or fluorescent lights work well
- Weak lighting may lead to yellowing or stunted growth
Tip: Use a programmable light timer to maintain consistency.
Substrate and Fertilization
Best Substrate
These are heavy root feeders, so substrate matters:
- Use nutrient-rich substrate (like Fluval Stratum or Aqua Soil)
- Or use inert sand/gravel + root tabs every 4–6 weeks
Don’t bury the crown of the plant (where leaves meet roots) as it may rot.
Fertilizer
- Root tabs are essential if you’re using plain gravel or sand
- Liquid fertilizer can help, especially for micronutrients
- CO2 is optional but boosts growth and leaf size
Planting Amazon Sword
- Choose a background corner or back wall of your tank
- Dig a shallow hole and place the roots in it
- Cover roots without burying the base/crown
- Space plants at least 4–6 inches apart to allow spread
Maintenance and Trimming
- Remove older, yellowing leaves at the base
- Trim outer leaves to maintain shape and light access
- Thin out runners if it propagates (see below)
- Clean algae off leaves gently if buildup occurs
Propagation
Amazon Swords reproduce by sending out runners with small plantlets:
- Wait for plantlets to develop roots and 4+ leaves
- Cut and replant them in another location
- Works best in nutrient-rich setups with consistent lighting
Compatible Tank Mates
Amazon Swords are safe for most peaceful community fish. They also make excellent hiding spots and shade for bottom dwellers and fry.
Good Tank Mates:
- Tetras
- Corydoras
- Gouramis
- Angelfish
- Shrimp and snails
Avoid These:
- Goldfish and large cichlids (they may uproot or nibble)
- Plant-destroying species like silver dollars
Common Problems and Solutions
Yellow Leaves?
Likely due to a nutrient deficiency (iron or potassium). Use root tabs and liquid fertilizer.
Melting After Planting?
Normal. Plants often lose older leaves as they adapt. New growth should emerge within 1–2 weeks.Algae on Leaves?
Caused by excessive light or stagnant water. Improve flow and reduce light duration slightly.
