Ask Finn

Alternanthera reineckii 'Mini' is a compact cultivar of the classic red stem plant, producing smaller leaves and a more restrained growth habit that makes it more useful in nano tanks and detailed midground positions than the standard form. Its leaves display striking magenta-red to deep purple-red coloration on the undersides, creating vivid contrast against green plants. Iron supplementation and CO2 are key to maintaining intense colour.

Common Diseases

Nutrient Deficiency (Iron/Magnesium)

Symptoms

Yellowing of new leaves while veins remain green; stunted growth; pale coloration instead of deep red

Treatment

Increase fertilization frequency and ensure all-in-one fertilizer contains chelated iron and magnesium; verify CO2 levels are adequate (30-40 ppm)

Algae Overgrowth (Green Spot/Black Beard)

Symptoms

Green or black fuzzy coating on leaves and stems; reduced light penetration; plant appears smothered

Treatment

Reduce photoperiod to 8-10 hours daily; increase water changes; add algae-eating shrimp (Red Cherry, Amano); manually remove affected leaves; ensure CO2 and nutrient balance

Melting (Tissue Decay)

Symptoms

Leaves become translucent, mushy, and dissolve; stems turn soft and brown; rapid deterioration

Treatment

Improve water quality with frequent partial water changes; ensure stable temperature (22-28°C); increase CO2 and lighting gradually; remove severely affected stems and replant healthy cuttings

Slow Growth/Poor Coloration

Symptoms

Stunted development; pale or greenish leaves instead of vibrant red; weak stem structure

Treatment

Verify high lighting (8-10 hours daily with 2+ watts per liter); increase CO2 injection to 30-40 ppm; boost macronutrient and micronutrient fertilization; ensure substrate is nutrient-rich
