Ask Finn

Lush, feathery stem plant with large whorls of finely divided leaves. Fast-growing background plant that creates a spectacular bushy effect. Needs good light and CO2.

Common Diseases

Nutrient Deficiency

Symptoms

Yellowing leaves, stunted growth, pale coloration, leaf holes, or necrotic spots on older leaves

Treatment

Increase fertilizer dosing, ensure adequate lighting (8-10 hours daily), and verify CO2 injection if using pressurized system. Test water parameters and adjust macronutrient and micronutrient supplementation accordingly

Algae Overgrowth

Symptoms

Green, brown, or black algae coating plant surfaces, reduced photosynthesis, plant deterioration

Treatment

Reduce lighting duration to 6-8 hours daily, perform 30-50% water changes weekly, introduce algae-eating fish or shrimp, and ensure adequate CO2 levels to favor plant growth over algae

Melting

Symptoms

Rapid leaf deterioration, mushy stems, translucent appearance, plant collapse within days

Treatment

Improve water quality through frequent water changes, ensure stable temperature (23-28°C), increase CO2 and nutrient supplementation, and remove severely affected portions. Melting often occurs during acclimation to new tank conditions

Bacterial Rot

Symptoms

Blackened or mushy stems, foul odor, progressive decay of plant tissue

Treatment

Remove affected plant portions immediately, perform 50% water change, improve water circulation with aeration, reduce organic waste through regular maintenance, and avoid overcrowding
