Natural Habitat

In nature, it occurs in:

• rivers

• wetlands

• floodplains

• shallow tropical waters

Natural conditions include:

• intense sunlight

• nutrient-rich environments

• seasonal flooding

Aquarium Placement

Best used as:

• Feature plant

• Mid-background focal point

• Color accent group

Ideal for:

• Dutch aquariums

• Nature aquascapes

• High-tech planted tanks

Large groups create dramatic color contrast.

Water Parameters

Recommended conditions:

• Temperature: 22–28°C

• pH: 5.5–7.0

• Soft water preferred

Stable conditions are important for maintaining vibrant colors.

Lighting

Requirements:

• High light

Under strong lighting:

• compact growth

• intense coloration

• healthy leaf development

Insufficient light often results in:

• green coloration

• elongated stems

CO₂ Requirements

• Strongly recommended

• Considered essential for best results

With stable CO₂:

• faster growth

• richer colors

• healthier structure

Most aquarists classify it as a high-tech plant.

Nutrient Requirements

Requires:

• regular fertilization

• nitrate

• phosphate

• potassium

• iron

• micronutrients

Nutrient deficiencies can quickly affect:

• color

• growth rate

• leaf quality

Growth and Propagation

Growth rate:

• Moderate

Propagation:

1. Cut healthy stem tops.

2. Replant cuttings.

3. Roots develop from stem nodes.

Regular trimming promotes:

• bushier growth

• denser plant groups

Compatibility

Compatible with:

• tetras

• rasboras

• discus

• angelfish

• corydoras

• shrimp

Best suited for dedicated planted aquariums.

Common Issues

Loss of Color

Usually caused by:

• weak lighting

• poor CO₂ levels

• nutrient deficiencies

Stunted Growth

Possible causes:

• unstable CO₂

• inadequate fertilization

Algae Problems

May occur when:

• lighting is high but nutrients are imbalanced

Care Difficulty

Advanced

Main requirements:

• high light

• stable CO₂ injection

• comprehensive fertilization

• consistent maintenance

Not generally recommended for beginner planted tanks.
