Common name: Green Fleece Algae

Codium is a genus of green macroalgae notable for its soft, spongy texture and its deep green, velvet-like appearance. It is often referred to as Green Fleece Algae or Dead Man's Fingers due to its distinctive morphology. In the reef aquarium, Codium species can be a visually appealing addition, providing a natural and lush backdrop. They are also beneficial as they perform photosynthesis, helping to oxygenate the water and remove excess nutrients like nitrates and phosphates. However, they can grow quite rapidly under the right conditions, so regular pruning may be necessary to keep them in check. Codium species are generally hardy and can thrive in a range of lighting conditions, making them suitable for various tank setups.
