Rotala sp. 'Pearl'

Species description

Care, breeding and tankmates

Plant profile

Placement

Midground

Best positioned in the midground or foreground depending on the tank size. It creates stunning focal points when planted in dense, small clusters. Ensure it receives unobstructed light to prevent lower leaves from shading out.

Botanical form

Stem

Features extremely small, tightly packed leaves that often curl slightly downwards, giving it a unique pearl-like appearance. Stems are fragile and slender. The coloration ranges from orange to deep pinkish-red under high light.

Growth

Medium

Exhibits a moderate growth rate compared to other Rotala species. It requires stable conditions to grow steadily without melting. With optimal light and CO2, it forms compact, bushy growth.

Substrate

Low

Column fertilization

Recommended

Relies heavily on water column dosing for its micro and macronutrients. Regular additions of iron and trace elements are crucial for its vibrant red and pink hues. Liquid fertilizers should be balanced to avoid algae outbreaks on its delicate leaves.

Root fertilization

None

While it takes in nutrients primarily through its leaves, a nutrient-rich substrate supports overall vitality. Root tabs can provide a secondary source of trace elements. A fine, active soil helps anchor its delicate root system.

Trimming

Occasional

Requires careful trimming with sharp scissors to avoid crushing the fragile stems. Cutting the tops encourages lateral branching, creating a denser bush. Replanting healthy tops is often more successful than leaving old, woody bottoms.

Propagation

Cuttings

Propagated through stem cuttings. Cut healthy terminal shoots and plant them carefully in fine substrate with tweezers. Ensure new cuttings have adequate space to receive light down to the base.

Sensitivity

Moderate

Highly sensitive to sudden changes in water parameters, especially fluctuations in CO2 and pH. It is prone to algae issues if water circulation is poor or nutrients are imbalanced. Not recommended for beginner aquarists due to its demanding nature.

Layout role

Midground

Excellent as a delicate accent plant or a small colorful bush in the midground. Its unique leaf shape provides a beautiful contrast against broader-leaved green plants. Perfect for nano aquariums or detailed aquascaping layouts.
