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

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

📍 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
