Nesaea praetermissa

Species description

Care, breeding and tankmates

Plant profile

Placement

Midground

It is best utilized in the midground of the aquarium where it can receive unobstructed light. Grouping a small number of stems creates a striking visual without casting too much shade on itself. Ensure it is not overshadowed by faster-growing, broader-leaved species.

Botanical form

Stem

It features rigid stems with somewhat fleshy, lanceolate leaves that grow opposite each other. The foliage can exhibit a range of colors from greenish-yellow to a vibrant, deep orange-red, depending strongly on the light intensity. The stems themselves often display a pronounced reddish hue.

Growth

Medium

The growth rate is generally moderate when supplied with ample light, CO2, and nutrients. It requires some patience as it establishes its root system before taking off vertically. In less-than-ideal conditions, growth can slow to a crawl, and the plant may slowly deteriorate.

Substrate

High

Nesaea praetermissa requires a nutrient-dense substrate, ideally a premium aquasoil, to sustain its demanding growth and vivid coloration. Its substantial root network relies heavily on the substrate for iron and vital macronutrients, which are essential for preventing stunted growth or pale leaves. A deep soil bed of around 3 inches ensures that the roots have ample space to anchor the delicate stems securely. Frequent insertion of root tabs is recommended to prevent nutrient depletion and keep the substrate consistently fertile for optimal plant health.

Column fertilization

Recommended

Consistent dosing of a comprehensive liquid fertilizer is critical for Nesaea praetermissa. It absorbs a significant portion of its required nutrition from the water column, and fluctuations can quickly lead to algae issues or plant melting. Regular iron supplementation is key to maintaining its warm, reddish tones.

Root fertilization

Recommended

A nutrient-rich substrate is highly recommended, as it develops a substantial root system that helps anchor the thick stems. Root tabs or a quality aquasoil provide a vital secondary source of nutrients that supports strong, healthy growth. Well-fed roots often result in thicker, more robust stems.

Trimming

Occasional

Due to its somewhat slow recovery, trimming should be approached with care. The top-and-replant method is usually the most successful; uproot the stem, trim away the older, often less attractive bottom half, and replant the vibrant top. If cutting the stem and leaving the bottom, ensure the remaining portion has plenty of light and healthy leaves to encourage new shoots.

Propagation

Cuttings

Propagation is done by taking stem cuttings from the healthy upper portions of the plant. Snip a cutting a few inches long, remove the lowest leaves, and plant it carefully into the substrate. Be patient, as it may take several days or even weeks for the new cutting to root and resume active growth.

Sensitivity

Moderate

This species is known to be somewhat delicate and unforgiving of poor conditions. It is highly sensitive to shading and poor water flow, both of which can lead to the rapid loss of lower leaves. It also dislikes hard water and may struggle or melt if the KH and GH are too high.

Layout role

Midground, accent

It serves as an excellent color accent in the midground, providing a splash of orange or red that draws the eye. Its rigid, structured appearance contrasts nicely with softer, bushier plants in the background. It is a rewarding plant for experienced aquascapers looking to add specific color highlights to their layout.
