Hygrophila lancea

Plantae›Tracheophyta›Magnoliopsida›Acanthaceae

📍 South America (Brazil, Bolivia)

The base species of the popular lancea group. A delicate, fine-stemmed plant with small, narrow lance-shaped leaves that grow in tight whorls around the stem. Under high light the leaves develop attractive reddish-pink tones. More compact and slower growing than most Hygrophilas, making it well-suited for the midground of Nature Aquarium and Iwagumi layouts.

Common Diseases

Nutrient Deficiency

Symptoms

Yellowing leaves, stunted growth, pale coloration, loss of red pigmentation under high light

Treatment

Increase fertilizer dosing (macro and micronutrients), ensure CO2 supplementation, verify adequate lighting; perform water tests to check nitrogen, phosphorus, and potassium levels

Algae Overgrowth

Symptoms

Green or brown algae coating stems and leaves, reduced light penetration, plant appears smothered

Treatment

Reduce photoperiod to 6-8 hours daily, increase water changes (30-50% weekly), add algae-eating shrimp or fish, improve water circulation, reduce excess nutrients

Melting

Symptoms

Leaves become translucent, mushy stems, rapid tissue breakdown after planting

Treatment

Ensure stable water parameters (pH 6.0-7.5, temperature 22-28°C), avoid drastic changes during acclimation, maintain good water circulation, trim affected portions and allow plant to recover

Slow Growth

Symptoms

Minimal new leaf development, stunted stem elongation, pale appearance despite adequate light

Treatment

Verify CO2 levels (20-30 ppm recommended), increase fertilizer dosing, ensure medium-high lighting (8-10 hours daily), check water temperature is within optimal range
