Ask Finn

Water Sprite is a versatile aquatic fern that can be grown both floating and rooted. The finely dissected, lacy fronds give it a delicate, feathery appearance. Floating specimens develop broader, more deeply lobed leaves and provide excellent surface cover and fry refuge. A classic, beginner-friendly plant that grows vigorously.

Common Diseases

Nutrient Deficiency

Symptoms

Yellowing leaves, stunted growth, pale coloration, leaf holes or transparent patches

Treatment

Dose with comprehensive liquid fertilizer (macronutrients and micronutrients) weekly; ensure adequate lighting and consider adding CO2 for faster growth

Algae Overgrowth on Leaves

Symptoms

Green or brown algae coating fronds, reduced light penetration, slowed growth

Treatment

Increase water changes, reduce light duration to 8-10 hours daily, add algae-eating fish (Otocinclus, Siamese Algae Eater), or manually remove affected leaves

Melting (Decay)

Symptoms

Leaves becoming translucent, mushy, or dissolving; rapid deterioration after planting

Treatment

Improve water quality with frequent water changes; ensure stable temperature (20–28°C); trim affected leaves; may recover if roots remain healthy

Poor Growth or Stunting

Symptoms

Minimal new leaf development, small or deformed leaves, slow overall expansion

Treatment

Increase lighting to medium-high levels, add liquid fertilizer, improve water circulation, and ensure pH is within 6.0–8.0 range
