🌿 The Melon Sword (Echinodorus osiris) is a classic broad-leaf sword with gently rounded leaves that shift from deep green to bronze with light and conditions. Built for a natural aquarium, it thrives in Father Fish–style deep soil with a sand cap—no CO2, no bottled fertilizers.
Why it’s great for a natural aquarium
- ✅ Rounded, colorful leaves—adds soft volume and contrast
- ✅ Low-tech growth—no CO2 or liquid dosing required
- ✅ Mid to background anchor—ideal for layered layouts
- ✅ Strong root system—stabilizes substrate and absorbs nutrients
- ✅ Beginner friendly—easy to plant and maintain
Care
- Lighting: low–moderate
- Placement: midground to background
- CO2: not required
- Growth rate: moderate
- Tank size: 20 gallons and up
🌱 Plant the crown at sand level and let roots run under the cap. Skip root tabs—your soil does the feeding.
Father Fish tip
“This sword loves a good soil bed. Plant it deep and walk away—it’ll grow clean, strong, and full without a single drop of ferts.”
👉 Build your natural aquarium with Aqua Preta soils, add fast growers from the Stem Plants Collection, and finish with easy accents from the Anubias Collection.
