Common name: Mermaid's Wine Glass

General information

Dichotomaria apiculata, commonly known as Mermaid's Wine Glass or Mermaid's Cup, is a species of calcareous green macroalgae that is popular among reef aquarium enthusiasts for its unique and attractive appearance. This alga is characterized by its cup-shaped, upright thalli that resemble small wine glasses, which can add a distinctive look to any marine aquascape.

Care

Mermaid's Wine Glass requires moderate to high lighting to thrive in a reef aquarium. It prefers strong water movement to mimic its natural habitat, where it is often found in shallow, turbulent waters. This species benefits from the addition of calcium and magnesium to the water to support its calcareous structure. It is important to maintain stable water parameters and avoid sudden changes that could stress the algae.

Symbiosis

While not known for hosting or forming direct symbiotic relationships with marine animals, Dichotomaria apiculata can contribute to the overall health of the reef aquarium by providing oxygen through photosynthesis and by competing with nuisance algae for nutrients.

Habitat

Dichotomaria apiculata is native to the Caribbean Sea and can be found in shallow reef environments. It is adapted to a range of conditions but typically inhabits areas with plenty of light and water movement.
