📍 South America

Echinodorus Uruguayensis is a large, bold sword plant from South America producing broad, dark-green leaves with a smooth texture and prominent venation, reaching up to 60 cm (23.6 in) in height. It is notable for tolerating cooler water than most tropical swords, thriving at temperatures as low as 16 °C. Its imposing size makes it best suited as a specimen background plant in larger aquariums.

Tank Mates

Otocinclus

Peaceful algae grazers that won't damage plant leaves and help maintain tank cleanliness

excellent

Emerald Dwarf Rasbora

Small, peaceful schooling fish that thrive in the same water parameters and won't uproot or damage plants

excellent

Red Cherry Shrimp

Beneficial invertebrates that graze algae and won't harm the plant; thrive in the same nutrient-rich environment

excellent

Anubias Barteri

Excellent companion plant with similar care requirements; creates layered aquascaping with contrasting leaf shapes

excellent

Bolivian Ram

Peaceful dwarf cichlid that tolerates cooler temperatures; may dig slightly but unlikely to uproot established sword

good

Amano Shrimp

Larger shrimp species that won't damage mature plants and provide excellent algae control

Common Diseases

Nutrient Deficiency (Iron/Macronutrient)

Symptoms

Yellowing or pale leaves, stunted growth, interveinal chlorosis (yellowing between leaf veins while veins remain green)

Treatment

Increase fertilization with all-in-one liquid fertilizers or add root tabs; ensure adequate lighting and CO2 for nutrient uptake

Algae Overgrowth (Black Beard/Brush Algae)

Symptoms

Dark, hair-like or brush-like algae coating on leaves and stems, reducing photosynthesis

Treatment

Reduce light duration to 8-10 hours daily, increase water changes, add algae-eating fish (Otocinclus, Siamese Algae Eater), or use targeted algaecide if severe

Root Rot

Symptoms

Mushy, blackened roots; foul odor from substrate; leaf yellowing and wilting despite adequate nutrients

Treatment

Improve substrate aeration, reduce organic buildup, perform partial water changes, ensure adequate water circulation; replant in fresh substrate if severely affected

Melting (Leaf Dissolution)

Symptoms

Rapid deterioration and dissolution of leaves, often after introduction to new tank or drastic parameter changes

Treatment

Maintain stable water parameters (pH 6.5–7.5, temperature 16–26°C); acclimate slowly to new conditions; remove affected leaves and ensure good water circulation
