Overview

Oblong leaves with softly ruffled edges emerge olive-green and deepen toward reddish-brown as light intensity climbs. This rosette-forming crypt spreads by runners into a midground clump and settles best left undisturbed, sometimes melting back after transplant before regrowing. Nutrient-rich substrate improves color and pace far more than dosing the water column.

Care

A hardy, adaptable crypt that tolerates a wide span of pH and hardness, making it forgiving of the water chemistry found in most established community tanks. Light can range from low to fairly high, though leaf color stays a plain olive-green in dim conditions and shifts toward bronze and reddish-brown tones as light intensity rises. CO2 is not required but speeds growth and deepens coloration when supplied. The plant resents being uprooted or moved once settled and may respond to disturbance with a temporary die-back of leaves.

Planting & trimming

Plant the rhizome with roots buried at least 1.5 to 2 inches into the substrate while keeping the crown itself at substrate level, uncovered. It can also be tied to driftwood or lava rock and allowed to root in over time, similar to other epiphyte-style crypt placements, though it grows best rooted in substrate. Space divisions about an inch apart if aiming for faster carpet-like spread, and avoid rearranging the plant once it has settled in.

Fertilizing

Roots are the main uptake pathway, so a nutrient-rich substrate or buried root tabs beneath the rhizome make a noticeable difference in growth speed and leaf color. In bare or inert gravel it survives but grows slowly and may stay pale; adding iron-rich tabs or switching to aquasoil corrects this. Liquid fertilizers help somewhat but are secondary to what the roots can draw from the substrate.

Propagation

Propagates readily by runners sent out along the rhizome, which produce plantlets that can be separated once they have their own root systems. Mature clumps can also be lifted and divided by cutting the rhizome into sections, each with at least one growth point and some roots attached. Division and separation are best done outside of a melt episode, when the plant is actively producing new leaves.

Problems

Newly planted specimens are prone to crypt melt, where leaves dissolve within days of introduction to a new tank; this is normal and the rhizome typically pushes fresh growth within a few weeks provided it is left undisturbed. Algae can settle on the slow-growing older leaves if light or nutrients are mismatched, so trimming affected leaves rather than the whole plant is usually the better response. Overall it is a low-maintenance species once established, with few pest or disease issues beyond the initial adjustment period.
