📍 Thailand

Ask Finn

A compact, attractive cultivar of Hygrophila siamensis with narrower, slightly undulated leaves that are bright green on top and pale on the underside. Very hardy and fast growing, it works well as a mid-background filler and helps suppress algae through nutrient uptake. Trims well and stays bushy.

Common Diseases

Nutrient Deficiency

Symptoms

Yellowing leaves, stunted growth, pale coloration, leaf holes or necrosis

Treatment

Increase fertilizer dosing (macro and micronutrients); ensure adequate lighting and consider adding CO2; test water parameters

Algae Overgrowth on Leaves

Symptoms

Green or brown algae coating leaf surfaces, reduced photosynthesis, slower growth

Treatment

Increase water changes, reduce photoperiod to 8-10 hours daily, add algae-eating fish (Otocinclus), manually remove affected leaves

Stem Rot

Symptoms

Blackening or mushy stems, leaf drop, foul odor from substrate

Treatment

Improve water circulation, reduce organic waste buildup, trim affected stems above rot line, increase water change frequency

Melting

Symptoms

Rapid leaf dissolution, transparent or translucent leaves, overall plant collapse

Treatment

Acclimate slowly to new tank conditions; maintain stable parameters (pH 6.0-8.0, temp 20-28°C); increase light and CO2 gradually
