About this item

Codium "Dead Man's Fingers" Macroalgae

Codium (Codium sp.), commonly known as “Dead Man’s Fingers”, is a distinctive green macroalgae prized for its thick, branching structure and velvety texture. Its cylindrical branches form dense clusters that create a bold, natural appearance in macroalgae displays and reef aquascapes.

Unlike many filamentous algae, Codium develops firm, spongy branches that maintain their shape even in moderate water flow. Its unique texture and structured growth pattern make it a visually striking addition to refugiums, display tanks, and natural reef-style aquascapes.

Available Options

Full Starter Plant

Single anchored plant or small fragment. Early branching structure beginning to develop. Ideal for establishing Codium in new areas of the aquarium.

Mature Colony

Established branching cluster. Dense multi-branch structure. Suitable for immediate aquascaping.

Care Information

Lighting	Low to High
Water Flow	Low to High
Placement	Rock surfaces or refugium zones
Care Level	Easy
Growth Rate	Low to Moderate
Nutrient Uptake	Moderate

Special Considerations

Codium forms a thick, spongy branching structure that differs from many other macroalgae. The branches contain internal siphonous cells which give the algae its firm yet flexible texture. While generally stable once established, Codium prefers stable parameters and moderate nutrient availability for consistent growth.

🌱 Propagation

Codium propagates through fragmentation and branching growth:

Branches can be trimmed and reattached to rock or substrate
Fragments may establish new colonies under stable conditions
Mature colonies expand through natural branching
