Variety of Rotala Macrandra · mini
📍 India (captive-propagated cultivar)
A miniaturised form of the famously demanding Giant Red Rotala, producing smaller, narrower leaves but retaining the same intense red-pink colouration when kept in optimal conditions. Requires high light, CO₂, and balanced macro and micro nutrients — particularly iron — to achieve its best colour. Grows slower than the standard species but is equally sensitive to nutrient deficiencies, which show as pale or washed-out leaves. Best kept by experienced planted tank hobbyists.
Tank Mates
Gentle algae grazers that won't damage delicate leaves and benefit from the same nutrient-rich environment
Larger shrimp that graze algae without harming plant tissue; thrive in high-tech planted tanks
Small, peaceful algae eaters that won't uproot or damage stem plants
Small, non-aggressive fish that add visual interest without disturbing plants or competing for nutrients
Companion stem plant with similar nutrient requirements; complements Rotala Macrandra Mini in midground layouts
Low-light moss that provides contrast and habitat without competing for high-light resources
Common Diseases
Nutrient Deficiency (Iron/Micronutrient)
Pale or washed-out leaves, loss of red coloration, stunted growth, yellowing between leaf veins
Increase iron and micronutrient dosing; test water parameters and adjust fertilizer regimen; ensure consistent CO₂ injection and high lighting
Algae Overgrowth
Green or brown algae coating leaves, reduced light penetration, plant growth slowing
Reduce photoperiod to 8–10 hours daily; increase water changes; add algae-eating shrimp or fish; maintain stable CO₂ and nutrient balance
Melting (Tissue Decay)
Leaves becoming translucent, mushy stems, rapid tissue breakdown after planting
Ensure stable water parameters (pH 5.5–7.0, temperature 20–27°C); maintain consistent CO₂ injection; perform gradual acclimation; improve water circulation
Potassium Deficiency
Yellowing of older leaves while veins remain green, weak stem growth, leaf curling
Dose potassium-rich fertilizers; maintain balanced macro and micronutrient ratios; increase water change frequency if nutrient buildup is suspected
