Hygrophila sp. 'Sarawak'

Species description

Care, breeding and tankmates

Plant profile

Placement

Midground

This plant is best suited for the midground to background of the aquarium. Its relatively fast growth and larger leaf size make it a great focal point. It should be planted in small groups to create a dense, bushy appearance. Ensure it has enough space so lower leaves receive adequate light.

Botanical form

Stem

It features elongated, lanceolate leaves with a somewhat rugged texture. The stems are robust and grow upright towards the surface, seeking light. Its overall form adds a very natural, wild look to the aquascape. Under strong light, the upper leaves may display subtle color changes.

Growth

Medium

It exhibits a fast growth rate, especially under optimal conditions. High light and CO2 injection will significantly accelerate its vertical growth. In lower tech setups, the growth is more subdued but remains steady. Regular maintenance is required to keep its size in check.

Substrate

Medium

Hygrophila sp. 'Sarawak' thrives in a moderately rich substrate, where its robust root system can anchor deeply and absorb essential nutrients. While it can grow in inert sands or gravels supplemented with root tabs, it shows optimal coloration and denser growth when planted in active aqua soil. A substrate depth of at least 4 to 5 centimeters is recommended to provide adequate room for its expanding roots and to ensure the stems remain securely seated against water flow.

Column fertilization

Recommended

Liquid column fertilization is highly recommended for this stem plant. It absorbs a majority of its nutrients directly from the water column through its leaves. A comprehensive liquid fertilizer applied regularly will yield the best results. Watch for signs of nutrient deficiencies on new growth.

Root fertilization

None

While it feeds heavily from the water column, a nutrient-rich substrate provides an excellent secondary nutrient source. Root tabs help establish a strong root system quickly. The roots help anchor the sturdy stems firmly in place. However, root feeding is not strictly mandatory if column dosing is high.

Trimming

Occasional

Regular trimming is essential to encourage lateral branching and a bushier shape. Cut the stem right above a node to promote new shoots. The trimmed tops can be easily replanted to propagate the plant. Avoid letting it overgrow and block light from shorter foreground plants.

Propagation

Cuttings

Propagation is straightforward and typical of most stem plants. Simply cut a healthy top portion and replant it directly into the substrate. The cutting will quickly develop new roots and continue growing. Leaving the bottom rooted portion will also result in new side shoots.

Sensitivity

Moderate

This species is generally hardy but can be sensitive to sudden changes in water parameters. It may melt if transitioned too quickly from emersed to submersed growth. It can also be susceptible to algae growth on its older leaves if flow is poor. Ensure good water circulation around the plant.

Layout role

Midground

It serves excellently as a contrasting background or midground accent. Its unique texture breaks up monotonous green areas effectively. It pairs well with fine-leaved plants or different textures. It can also be used to hide aquarium equipment effortlessly.
