01

Overview

Gracilis brings scale to the red palette: thick stems, long wavy-margined leaves, and a glow that runs pink-copper under strong light. Hailing from West African waterways, it grows large and fast enough to anchor the back of a sizable high-tech tank by itself.

Aquascaping use

Use it as the towering warm mass behind green midgrounds in tanks sixty centimeters and taller. Two or three stems make a statement; a full row makes a wall of ember.

03

Planting

Plant deep and firm; the heavy stems lever loose in flow until rooted. Give each stem generous clearance for its leaf span.

Substrate note

Nutrient-bearing substrate

04

Light & CO₂

High light and steady CO₂ keep the color molten and the internodes close. Under moderate energy it turns olive and rangy.

Light requirementHighIntensity categories are comparative, not precise PAR targets.
Supplemental CO₂RequiredAll aquatic plants use CO₂; this describes whether injection is needed.

05

Substrate & fertilization

A voracious column feeder; keep nitrogen, phosphate, and iron all comfortably present. Deficiencies twist the big leaf tips first.

Feeding behavior: Water-column feeder. Nutrient demand: high.

06

Growth, trimming & propagation

Top above strong nodes and replant hefty crowns; spindly cuttings struggle. Its size means each trim meaningfully reshapes the layout.

Propagation method

Stem cuttings

Common problems

  • !Demands real vertical and horizontal space
  • !Fades to olive without high energy
  • !Tip stunting under nutrient shortfalls
