The Amazon Sword (Echinodorus bleheri/amazonicus) is a hardy, fast-growing aquatic plant ideal for beginner to intermediate aquarists. It thrives in tanks 20+ gallons with moderate light (6500K), temperatures of 22-28°C (72-82°F), and pH 6-8. As a heavy root feeder, it benefits from nutrient-rich substrates or root tabs but doesn’t require CO2. Propagation occurs via runners, and it reaches 14-20 inches tall, making it a striking background plant. Avoid shrimp tanks due to pesticide treatments on commercially sold specimens.
Quick Care Summary
- Tank Size: 20+ gallons (75+ liters)
- Water Temperature: 22-28°C (72-82°F)
- pH: 6.0-8.0
- Diet: Root tabs or nutrient-rich substrate; liquid fertilizer optional
- Temperament: Peaceful; may crowd small tanks
- Difficulty: Easy
How to Set Up a Tank for Amazon Swords?
- Tank Size: Minimum 20 gallons (75 liters) for one plant; larger tanks needed for multiple specimens.
- Substrate: Fine, nutrient-rich substrate (e.g., mineralized topsoil) or use root tabs. Depth: 2-3 inches.
- Lighting: Moderate (6500K); supports growth without promoting excessive algae.
- CO2: Optional; speeds growth but not required.
What Are the Ideal Water Parameters?
- Temperature: 22-28°C (72-82°F) (Sources conflict slightly: Source 1 states 22-28°C, Source 3 suggests mid-high 70s Fahrenheit.)
- pH: 6.0-8.0 (Source 1 notes 6-8, Source 3 prefers neutral to slightly acidic.)
- Water Hardness: Very soft to hard (adaptable).
- Flow: Gentle, diffuse current.
How to Feed Amazon Swords?
- Root Tabs: Primary nutrient source; place directly under roots.
- Liquid Fertilizer: Less effective but usable if no root tabs available.
- Deficiency Signs: Yellowing lower leaves indicate nutrient lack.

Common Problems and Solutions
- Algae Blooms: Caused by excess light/nutrients; reduce lighting duration or add floating plants.
