Variety of Alternanthera Reineckii · rosanervig

📍 South America (cultivar)

Rosanervig is a striking cultivar of Alternanthera with green upper leaf surfaces crossed by vivid pink-white veining, while the undersides remain deep red-pink. The contrasting vein pattern is unique in the aquatic plant world and makes it a focal accent in Dutch and Nature Aquarium layouts. Requires good light and CO2 for the best colour expression.

Tank Mates

Common Diseases

Nutrient Deficiency (Iron/Macronutrients)

Symptoms

Yellowing leaves, pale coloration, loss of pink-white veining, stunted growth

Treatment

Increase fertilizer dosing (liquid all-in-one or separate macro/micro fertilizers). Ensure CO2 is adequate and lighting is high. Test water parameters and adjust based on results.

Algae Overgrowth (Black Beard Algae)

Symptoms

Dark, hair-like algae coating on leaves and stems, reduced light penetration

Treatment

Increase water changes, reduce light duration to 8-10 hours daily, boost CO2 levels, and manually remove affected leaves. Add algae-eating shrimp or fish like Otocinclus.

Melting (Leaf Deterioration)

Symptoms

Leaves becoming translucent, mushy, or dissolving; sudden leaf loss

Treatment

Ensure stable water parameters (pH 6.0-7.0, temperature 22-28°C). Increase CO2 and light gradually if recently added. Perform 25-30% water changes and remove decaying tissue.

Slow Growth or Pale Coloration

Symptoms

Minimal new growth, loss of pink-white vein contrast, weak stems

Treatment

Verify CO2 injection is functioning (target 20-30 ppm). Increase light intensity to 8-10 hours daily. Boost macro and micronutrient fertilization and ensure substrate contains nutrients.
