A large, robust rosette plant from South America characterized by long, ribbon-like, somewhat translucent green leaves. It develops a massive root system and is well-suited as a background plant or solitary focal point in larger aquariums. Its large, sturdy leaves serve as excellent spawning sites for species like angelfish.

Layout Fit

Uruguay Sword usually works best from the midground into the background and needs enough room to mature at about 55 cm tall and 40 cm wide.

Water Window

Aim for freshwater conditions with a steady current, plus 16 to 28 °C, pH 6 to 7.5, and 2 to 12 dGH.

Upkeep Rhythm

Expect moderate growth with low maintenance. It usually stays easy to manage between normal maintenance sessions.

Uruguay Sword Care Guide Summary

The Uruguay Sword is a rosette or crown plant that usually works best from the midground into the background. Give it room to reach about 55 cm tall and 40 cm wide, so the mature plant still fits the layout. It is approachable for newer planted-tank keepers once the initial planting is done correctly. In day-to-day care, it responds best to moderate light, freshwater conditions, and a steady current. It usually grows well without added CO2. Keep this species within a comfortable range of 16 to 28 °C, pH 6 to 7.5, and 2 to 12 dGH.

Uruguay Sword Planting, Feeding & Maintenance

The Uruguay Sword does best when the setup matches the way it naturally grows. Plant it with enough room for the crown and new roots to establish cleanly. Most of its uptake happens through the root zone, so root tabs or an enriched bed matter more than frequent water-column dosing. A nutrient-rich substrate helps it settle faster and usually supports fuller growth. Keep the routine steady: moderate light and high nutrient demand usually give better results than big swings from week to week. This plant can also adapt to emersed growth, which is useful for growers who propagate outside the display tank.

Aquarium Benefits

Breaks lines of sight
Useful spawning site

The Uruguay Sword can work very well in a mixed tank, but its value depends on how well it handles fish pressure and how much usable cover it really provides. It is less likely to be chewed by curious fish, and its tough / leathery leaves usually help it hold up in calm community tanks. Once rooted or attached, it is relatively dependable and easier to keep in place around more active fish. It adds some usable cover without turning the layout into a dense thicket. Its canopy can shade neighboring plants, so leave space around lower growers that need direct light. Aquarists also lean on it for breaking up sight lines and a useful spawning site, not just for appearance.

Uruguay Sword Propagation

This species is usually propagated by plantlets and rhizome division. With moderate growth and low upkeep, it rarely crowds neighboring plants in a hurry. That gives you a better sense of whether simple trimming is enough or whether it is smarter to plan division, replanting, or thinning before the layout closes in.
