Common name: Halimeda copiosa

General information

Halimeda copiosa, commonly known as Copious Halimeda, is a species of calcareous green macroalgae that is popular among reef aquarium enthusiasts. This alga is part of the Halimedaceae family and is known for its segmented, flat, and leaf-like appearance, which resembles a series of small green coins stacked together. The calcification within its tissues gives it a rigid structure and helps it to maintain its shape within the water column.

Care

Halimeda copiosa requires a stable marine aquarium with strong lighting and moderate to high water flow to thrive. It is important to maintain calcium levels as this alga absorbs calcium carbonate from the water to build its structure. It can be a good indicator of the tank's calcium status. Halimeda can compete with corals for space and nutrients, so it should be pruned to prevent overgrowth.

Symbiosis

While not hosting symbiotic fauna like some corals or anemones, Halimeda copiosa does play a role in the reef ecosystem by providing shelter and food for small invertebrates and fish larvae. Its dense growth can create microhabitats within the aquarium.

Habitat

Halimeda copiosa is found in tropical and subtropical oceans around the world, often in shallow waters where sunlight can reach the seabed to support photosynthesis. It is commonly found on reef slopes and lagoons, where it contributes to the structure and stability of the reef by depositing calcium carbonate.
