Description
Plant Profile
Echinodorus ‘Chocolate Marble’, often referred to as the Chocolate Marble Sword, is a hybrid cultivar prized for its rich, variegated foliage. True to its name, this unique sword plant produces broad leaves decorated with a mottled pattern of deep chocolate-brown, bronze, and olive-green blotches. Reaching heights between 10 and 16 inches, it makes a handsome midground centerpiece or a standout background plant in medium to large aquariums. Under moderate to bright lighting, its marbling contrast becomes especially pronounced, bringing distinct pattern and warm color to your aquascape. Like most sword plants, it is naturally hardy and adaptable, making it an excellent, low-maintenance option for beginners looking for something a bit different than standard green foliage.
Key Features & Notes
Broad, marbled leaf blades feature deep chocolate-brown, bronze, and olive-green blotches.
Moderate height offers versatile placement as a midground centerpiece or background focal point.
Hardy and adaptable rosette habit thrives across a wide range of water parameters.
Care & Planting Instructions
Prep the plant by removing it from the pot and clearing all rockwool from the roots.
Plant the roots deeply into your aquarium soil, keeping the crown of the plant resting just above the substrate line to prevent rot.
All Echinodorus are heavy root feeders that rely on rich substrate nutrition; placing root tabs near the base supports steady, healthy leaf development.
Supplemental CO2 injection and moderate-to-high lighting accelerate growth and sharpen the contrast of the marbled patterns, though the plant will still grow reliably in low-tech setups.
Maintain stable water parameters to prevent leaf shedding during the initial transition period.
Final size and coloration depend entirely on your specific aquarium conditions; please note that photos are a representation, and individual plants may vary.

Frequently Asked Questions
1. How do I prune an Echinodorus when it grows too large?
Prune older or overgrown outer leaves individually near the root crown using sharp aquascaping scissors. Avoid cutting across leaf blades, as damaged leaf tips will turn brown rather than regrowing.
2. How do I maintain and enhance the dark marbling pattern on Chocolate Marble Sword leaves?
Provide moderate-to-high lighting and supplement the substrate with iron-rich root tabs. Under low light, the brown and bronze speckling can fade, causing new foliage to emerge in a solid olive-green shade.
3. Will the marbled pattern on emersed leaves change when the plant transitions to underwater growth?
Yes. As old emersed leaves drop off, the new submersed leaves will emerge thinner, glossier, and with more defined chocolate-brown and bronze blotches scattered across the foliage.
