The Algae Codium Fragile as pictured above and below is a species of algae that we sometimes come across in our marine reef tanks. There are other names for this type of algae such as dead man’s hands or dead man’s fingers. This is a slow growing algae in my reef tank and it only shows up when the water conditions are very good. When I see this algae start to grow I can tell that my other algae’s such as Halimeda will soon sprout and grow as well. Right now I am letting this algae grow even though it is considered a nuisance algae becouse there is a galaxy coral right on top of it. Nether the galaxy coral or the codium fragile seem to be effected by one another. I would assume that this would make a good algae to have in a refuge because of its slow growing nature and its “hairy” tentacles may appeal to pods.
