Echinodorus Horizontalis FJ

Echinodorus horizontalis, a medium-sized sword plant from the Amazon region, thrives in shaded areas of marsh woods and temporarily flooded forests. It adapts to changing water levels by developing submersed leaves that resemble its emersed ones. In the aquarium, it grows well when cultivated submersed and even produces flower stalks. Hobbyists play a crucial role in preserving this species, as it is now rarely cultivated and hard to find. The leaves of E. horizontalis are longish-oval, with transparent grid-like patterns and a light to medium green color. It reaches a height of 15 to 20 cm in aquariums but can spread its leaf rosette to 30 to 50 cm. It prefers slightly acidic water, good CO2 supply, and nutrient-rich substrate. Iron deficiency may cause chlorosis.
