Alien Fingers Alga

Care Summary

Alien Fingers Alga (Codium species) grows in distinctive dark green, cylindrical finger-like branches that give it an unmistakable appearance. It is slow growing and relatively undemanding — moderate lighting and flow are sufficient. Considered a display macroalgae rather than a nutrient exporter. Generally ignored by herbivores. Does not go sexual like Caulerpa species, making it more stable in the display tank. Keep flow moderate to prevent detritus collecting in its branches.
