Common name: Green Felt Algae

General information

Codium edule, commonly known as Green Felt Algae or Codium Algae, is a species of marine green algae that is often found in reef aquariums. It is characterized by its spongy, velvet-like texture and deep green color, which can add a natural and lush appearance to the tank. This algae is not just decorative; it also plays a role in nutrient export, helping to remove excess nutrients from the water and improve water quality.

Care

Codium edule is relatively easy to maintain in a reef aquarium. It prefers moderate to high lighting and some water flow, but it is not particularly demanding. It can be attached to live rock or other surfaces using a safe aquarium glue or a rubber band until it naturally anchors itself. Regular pruning may be necessary to keep its growth in check and to prevent it from overshadowing other inhabitants of the tank.

Symbiosis

While Codium edule does not have any specific symbiotic relationships with fish or invertebrates, it can provide a microhabitat for small beneficial organisms like copepods and amphipods. These tiny creatures can use the algae as a refuge and breeding ground, which in turn can serve as a natural food source for fish and other inhabitants.

Habitat

In the wild, Codium edule is found in shallow waters, often attached to rocks and coral rubble. It is a hardy species that can adapt to a range of conditions, making it suitable for various types of marine aquariums. It is important to source this algae from reputable suppliers to ensure it is free from pests and diseases that could harm the aquarium ecosystem.
