Codium, or "Dead Man's Fingers" is a hardy green macroalgae recognized for its thick finger-like branches and soft velvety texture. In nature it grows attached to rock or hard substrate in shallow coastal waters, forming dense clusters that sway gently in the current. When grown in aquariums it adds a natural reef appearance while also helping absorb excess nutrients from the water. It is an excellent choice for refugiums.
