🟤 Reddish-bronze through the whole leaf. Whole leaf visible warm colour — not just underside (unlike Limnophila). CO2 + iron fertiliser trigger deepest bronze.
✔ No CO2 for growth; same care as other Hygrophilas. CO2 for colour only. pH 6–7.5. TDS 100–350. Compact mid-ground: 15–30cm. Bushy branching after trim.
🌱 Three Keys
Third Hygrophila: Corymbosa (large green bg) + Angustifolia (narrow green bg) + Araguaia (compact bronze mg) = complete three-zone Hygrophila setup with same care for all three.
With Limnophila Aromatica: Purple mid-ground (Limnophila) + bronze mid-ground (Araguaia) = two warm-colour mid-ground plants; two different leaf architectures; two complementary warm tones.
Betta colour: Warm bronze behind Red Bettas (tone echo); behind Blue Bettas (warm/cool contrast). Most colour-aware Betta backdrop in catalog.
Depth gradient: Monte Carlo carpet (front) → Araguaia bronze mid-group → Corymbosa green background. Three layers; three textures; foreground-to-background colour gradient from catalog plants.
