Echinodorus ‘Chocolate Marble’ Care Guide

Common Name: Chocolate Marble Sword
Difficulty Level: Easy to Moderate
Family: Alismataceae

General Description:

Echinodorus ‘Chocolate Marble’ is a striking sword plant distinguished by its marbled pattern of deep green, brown, and reddish tones. New leaves often emerge with rich chocolate hues that intensify under good lighting and nutrient availability. Its broad, patterned foliage makes it an excellent focal plant for planted aquariums, adding texture and warm coloration to the layout. Like most Echinodorus species, it is hardy and well suited for both beginner and intermediate aquarists.

Care Requirements:

1. Tank Size:

Minimum Tank Size: 20 gallons (75 liters)

2. Lighting Requirements:

Lighting: Moderate

Moderate light enhances the marbled coloration and promotes healthy leaf development. Lower light may result in greener leaves with less contrast.

3. CO₂ Requirements:

CO₂: Not required

CO₂ supplementation is optional but can improve growth rate, leaf size, and overall coloration.

4. Water Parameters:

Temperature: 22–28°C (72–82°F)
pH: 6.0–7.5
Hardness: Soft to moderately hard

5. Substrate:

Substrate Type: Nutrient-rich substrate strongly recommended

This is a heavy root feeder. A fertile substrate or root tabs are essential for sustained growth and strong coloration.

6. Fertilization:

Nutrients: Moderate

Regular nutrient availability supports leaf size and color intensity. Iron contributes to deeper red and brown tones.

7. Maintenance:

Growth Rate: Moderate

Remove older outer leaves as needed to encourage new growth and maintain a clean appearance.

8. Propagation:

Propagation Method: Runner shoots / plantlets

Produces flower stalks with plantlets that can be separated and replanted once roots develop.

9. Placement in Tank:

Placement: Midground to Background

Best used as a focal point in larger aquariums due to its size and bold leaf pattern.

Summary:

Echinodorus ‘Chocolate Marble’ is a beautiful and robust sword plant that adds rich, warm tones and visual interest to planted aquariums. With adequate nutrients at the roots and moderate lighting, it develops striking marbled foliage and steady growth. An excellent centerpiece plant for aquarists seeking color without excessive maintenance.
