One of the most sought-after Rotala species in competitive aquascaping. Produces fine, needle-like leaves and deep pink-to-red colouring. Requires pristine water, high light, CO2, and regular trimming to maintain shape.

Tank Mates

Red Cherry Shrimp

Shrimp will not damage delicate foliage and help control algae; they thrive in the same high-light, nutrient-rich environment

excellent

Amano Shrimp

Excellent algae control without harming plants; compatible with high-tech planted tank setups

excellent

Ember Tetra

Small, peaceful fish that won't uproot or damage stems; adds visual contrast with their red coloration

good

Rotala Rotundifolia

Companion stem plant with similar care requirements; creates layered aquascaping depth

excellent

Bucephalandra

Low-growing companion plant that complements tall Rotala Vietnam in background/midground layouts

Common Diseases

Nutrient Deficiency (Iron/Macronutrients)

Symptoms

Yellowing leaves, stunted growth, pale coloration, loss of red pigmentation

Treatment

Increase fertilizer dosing with all-in-one or macronutrient supplements; ensure CO2 levels are adequate (30-40 ppm); test water parameters and adjust accordingly

Algae Overgrowth (Green Spot, Black Beard)

Symptoms

Green or black algae coating on leaves and stems, reduced light penetration, plant decline

Treatment

Increase water changes (50% weekly), reduce lighting duration to 8-10 hours daily, add algae-eating shrimp (Red Cherry, Amano), manually remove affected leaves, ensure CO2 is stable

Melting (Tissue Decay)

Symptoms

Leaves become translucent, mushy, and dissolve; stems weaken and collapse

Treatment

Improve water quality with frequent partial water changes; ensure stable temperature (24-26°C), adequate CO2, and consistent lighting; remove severely affected stems and replant healthy cuttings

Poor Coloration (Pale/Green Leaves)

Symptoms

Loss of red pigmentation, leaves remain green instead of pink-red, weak growth

Treatment

Increase light intensity (8-10 hours daily at 60+ PAR); boost CO2 injection to 30-40 ppm; add comprehensive fertilizers with micronutrients; ensure phosphate and potassium levels are sufficient
