📍 South America

Echinodorus Bleheri, the Broad-Leaf Amazon Sword, is the quintessential large background plant of the freshwater aquarium. It produces broad, bright-green lanceolate leaves that can reach 50 cm (19.7 in), creating a dramatic focal point in larger tanks. It is a heavy root feeder and benefits greatly from nutrient-rich substrate or regular root tab fertilisation.

Common Diseases

Nutrient Deficiency (Iron/Micronutrient)

Symptoms

Yellowing of new leaves while veins remain green (chlorosis); stunted growth; pale coloration

Treatment

Increase fertilization frequency with liquid fertilizers containing iron and trace elements; verify lighting is adequate (60-120 PAR); check substrate nutrient levels and add root tabs if needed

Algae Overgrowth on Leaves

Symptoms

Green, brown, or black algae coating leaf surfaces; reduced photosynthesis; leaf deterioration

Treatment

Increase water changes (25-30% weekly); reduce lighting duration to 8-10 hours daily; add algae-eating fish like Otocinclus or Siamese Algae Eater; manually remove affected leaves if severe

Root Rot

Symptoms

Mushy, blackened roots; foul odor from substrate; leaf yellowing and wilting; plant fails to grow

Treatment

Improve substrate drainage and water circulation; reduce organic waste buildup; perform partial water changes; consider replanting in fresh substrate if severely affected; ensure adequate oxygen in substrate

Melting (Leaf Deterioration)

Symptoms

Rapid leaf breakdown and disintegration; transparent or translucent leaf tissue; plant appears to dissolve

Treatment

Gradually acclimate plant to new tank conditions over 2-3 weeks; maintain stable water parameters (pH 6.5-7.5, temperature 22-28°C); increase lighting and CO2 availability; ensure adequate nutrient supplementation
