Hygrophila lancea "Sarawak"

Species description

Care, breeding and tankmates

Plant profile

Placement

Midground

With its relatively narrow leaves and bushy growth potential, it is an excellent plant for the midground or background. When planted in groups, it forms a dense thicket that transitions smoothly between shorter foreground plants and taller background species. It can also be placed near hardscape to soften harsh lines.

Botanical form

Stem

It features long, narrow, lanceolate leaves that are generally olive to bright green. Under intense light, the tips and new growth can take on attractive brownish or reddish tinges. The stems grow relatively upright but readily branch out, creating a naturally bushy and textured appearance.

Growth

Medium

This variety has a moderate to moderately fast growth rate, especially when supplemented with CO2 and high lighting. It grows steadily but generally doesn't require the aggressive, weekly pruning that some other fast-growing stem plants demand. In low-tech tanks, its growth is slower and highly manageable.

Substrate

Medium

Hygrophila lancea "Sarawak" prefers a moderately enriched substrate environment, easily satisfied by aquasoil or gravel treated with targeted root tabs. A depth of 4 to 6 centimeters is ideal to anchor its spreading root structure and support its distinctive lanceolate leaves. While it readily absorbs some elements from the water column, consistent root feeding helps maintain its optimal growth rate and healthy coloration.

Column fertilization

Recommended

Liquid fertilization is very beneficial as the long leaves efficiently absorb nutrients directly from the water column. A consistent dosing schedule of a comprehensive fertilizer keeps the plant vigorous and colorful. It reacts positively to adjustments in water column nutrients, recovering quickly from minor deficiencies.

Root fertilization

None

A nutrient-rich substrate strongly supports the long-term health of Hygrophila lancea 'Sarawak'. Providing root tabs or a quality soil substrate will encourage the development of a strong root system, leading to thicker, healthier stems. Robust roots also help the plant endure periods of fluctuating column nutrients.

Trimming

Occasional

Regular pruning encourages the plant to grow bushier and prevents the lower portions from becoming shaded and bare. Simply trim the tops just above a node and replant them to expand your cluster. The trimmed stems will reliably produce new side shoots, increasing the overall density of the group.

Propagation

Cuttings

Propagation is simple and achieved via stem cuttings. Any healthy cut stem placed into the substrate will quickly develop roots. Additionally, lateral shoots can be snipped off and planted independently to multiply the plant easily.

Sensitivity

Moderate

It is a relatively undemanding and hardy species, adaptable to a variety of water parameters. However, it can be sensitive to severe potassium deficiency or sudden drops in CO2 levels, which may cause some leaf melt. It prefers stable environments but generally recovers well from minor setbacks.

Layout role

Midground, Background

It acts as a superb structural filler in the midground or background. Its narrow leaves provide a pleasing textural contrast against broad-leaved species like Anubias or fine-leaved mosses. The olive-green tones bridge the gap nicely between bright green and deep red aquatic plants.
