Here’s all about Hygrophila polysperma — a fast-growing, beginner-friendly stem plant that’s ideal for new aquariums and known for its hardiness, rapid growth, and ability to control algae by nutrient competition.
Scientific Name: Hygrophila polysperma
Common Names: Indian Swampweed, Dwarf Hygro
Family: Acanthaceae
Origin: Southeast Asia (India, Bangladesh, Thailand)
Type: Stem plant
Height: 20–40+ cm (8–16 inches)
Width: 5–8 cm spread (clusters)
Leaf Shape: Narrow oval to lanceolate, opposite leaf arrangement
Leaf Color: Light green to pinkish-brown under high light
Growth Rate: Very fast
Parameter | Ideal Range |
---|---|
Temperature | 22–30°C (72–86°F) |
pH | 6.5–7.5 |
Hardness | Soft to moderately hard (GH 3–12) |
Lighting | Low to high (color varies with light) |
CO₂ | Not essential but promotes faster, bushier growth |
Substrate | Not picky; grows even in inert gravel, though nutrient-rich substrate improves performance |
Propagation: By stem cuttings; simply cut and replant tops
Spacing: 2–3 cm between stems to avoid overcrowding
Trimming: Regular trimming needed to prevent surface takeover
Replanting: Cut top portions root easily when planted in substrate
Standard Green: Commonest form; bright green under moderate light
Sunset Hygro / Rosa Nervis: Rare cultivar with pink veins and reddish hues
Variegated types: Sometimes found with mottled leaves
Excellent for new tank setups to stabilize the environment
Great for absorbing excess nutrients, reducing algae risk
Can grow emersed in open tanks or paludariums
If left unchecked, it can grow out of the water and flower
Problem | Cause |
---|---|
Pale or yellow leaves | Iron deficiency or poor substrate nutrients |
Leggy growth | Not enough light or insufficient trimming |
Leaves melting | Transition shock (emerse to submerse) |
Overgrowth | Regular trimming required due to fast growth |
Very compatible with shrimp, small community fish, and bettas
Avoid with goldfish or large cichlids that may uproot or nibble plants
Great hiding spot for fry or small fish due to dense foliage
