01
Overview
Reni solves the sword-keeper's usual problem: wanting Echinodorus color without surrendering half the tank. It matures at a domestic scale, and its dark red new growth is among the deepest in the compact cultivars.
02
Aquascaping use
It fits the midground of a standard sixty-centimeter tank as the centerpiece larger swords cannot be. Surround it with low green plants to frame the dark rosette.
03
Planting
Set it in rich substrate with modest clearance; its restraint is genetic, not a response to cramping, so give it honest room anyway.
Rich substrate
04
Light & CO₂
Medium light maintains the red; it manages fine without CO₂. More energy mostly quickens leaf turnover.
05
Substrate & fertilization
Root tabs on schedule keep the succession of red leaves coming. Iron availability shows directly in new-leaf depth.
Feeding behavior: Root feeder. Nutrient demand: high.
06
Growth, trimming & propagation
Remove olive-aged leaves to showcase incoming red ones. Plantlets from stalks propagate it faithfully.
Adventitious plantlets
07
Common problems
- !Red depth tracks feeding and light closely
- !Still needs more floor space than stems of equal height
- !Transplant shock shows as a pause in leaf production
