Murdannia keisak

Species description

Care, breeding and tankmates

Plant profile

Placement

Midground

This plant is best suited for the background due to its strict, upright growth. It can also be placed in the midground of larger aquariums if trimmed appropriately. Planting in dense groups creates a striking visual impact similar to a miniature bamboo forest.

Botanical form

Stem

It features straight, thick stems with lanceolate, alternating leaves that wrap slightly around the node. The strict vertical growth and distinct leaf shape give it a strong resemblance to bamboo. It maintains a light green color across most conditions.

Growth

Fast

Murdannia keisak exhibits a fast growth rate under high lighting and CO2 supplementation. It will quickly reach the surface, often growing emerged if the tank is open. In lower-tech setups, growth is significantly slower but still manageable.

Substrate

High

Column fertilization

Recommended

Liquid fertilizers are ideal for maintaining strong growth in this fast-growing stem plant. Regular dosing of a complete NPK fertilizer ensures that the stems grow thick and robust. The leaves will readily absorb nutrients directly from the water column.

Root fertilization

Recommended

While not strictly root-dependent, a nutrient-rich substrate helps establish a strong foundation. Root tabs can provide a slow-release nutrient source that supports prolonged health. A healthy root system prevents the stems from uprooting as they grow taller.

Trimming

Occasional

Trim by cutting the stem at the desired height and replanting the tops if propagation is desired. The lower portion will typically send out one or two side shoots. Frequent trimming is required to prevent it from shading the entire aquarium.

Propagation

Cuttings

Propagation is very simple by means of stem cuttings. Snipping a healthy top and pushing it gently into the substrate will quickly yield a new plant. Side shoots can also be carefully removed and planted.

Sensitivity

Moderate

It is relatively hardy but can be sensitive to very soft water or extreme fluctuations in parameters. Poor circulation can lead to algae on its lower leaves. Ensure good flow to keep the foliage clean and healthy.

Layout role

Midground, Background

Murdannia keisak is excellent for creating vertical lines in an aquascape. Its bamboo-like appearance offers a unique texture that contrasts well with broad or round leaves. It works beautifully in Asian-themed layouts or nature aquariums.
