Bacopa crenata

Species description

Care, breeding and tankmates

Plant profile

Placement

Foreground

It is best positioned in the midground of the aquarium, where its height can be easily managed. Grouping several stems together creates an attractive, focal bush. Its straight, upright growth nicely complements harder aquascape elements like wood and stone.

Botanical form

Stem

It features distinctively serrated or scalloped leaf edges, setting it apart from other Bacopa species. The leaves are light green, opposite, and somewhat delicate in texture. Stems are relatively thin but rigid enough to maintain an upright posture.

Growth

Slow

This species grows at a moderate pace, making it easy to manage without frequent pruning. It establishes quickly once planted and acclimates well to submerged conditions. The moderate growth ensures it does not easily overshadow slower-growing foreground plants.

Substrate

Medium

Bacopa crenata benefits from a moderately nutrient-rich substrate, such as a quality aqua soil or a gravel bed supplemented with root tabs. Its roots penetrate the substrate to a moderate depth, establishing a robust anchor that supports the plant's leafy stems and absorbs essential minerals. A substrate layer of at least 4 to 6 centimeters is recommended to ensure the root system has ample space to expand and extract sustenance. Providing a fertile base helps maintain the vibrant green coloration and overall vitality of this elegant stem plant.

Column fertilization

Recommended

Liquid fertilization is beneficial as it readily absorbs nutrients directly from the water column. Providing adequate iron and micronutrients prevents the young leaves from turning pale. Regular weekly dosing maintains strong, vibrant new growth.

Root fertilization

None

While a nutrient-rich substrate is beneficial, it is not absolutely necessary. Root tabs can be added near the base to boost early development. The roots serve mainly as anchors but will supplement nutrient intake if the column is lean.

Trimming

Occasional

Trim by cutting the top portion of the stem with sharp aquascaping scissors. Replanting the tops will quickly form a denser patch. The remaining lower stems will branch out, adding volume to the plant group.

Propagation

Cuttings

Propagation is straightforward via stem cuttings. Simply cut healthy stems and insert them an inch deep into the substrate. They will form roots within a week and continue growing.

Sensitivity

Moderate

It is quite hardy and adapts well to various water hardness and pH levels. However, it can melt if exposed to sudden, drastic shifts in water parameters. It handles typical algae treatments well when dosed according to instructions.

Layout role

Nano, Midground, Foreground, group

It provides excellent textural contrast due to its crenated leaf edges. Often used as a midground transitional plant between carpet plants and taller background species. Its bright green coloration softens the transitions between dark hardscape and red plants.
