Common name: Halimeda Plant

General information

Halimeda incrassata, commonly known as the Halimeda Plant or Coin Vine, is a species of calcareous green macroalgae that is popular among reef aquarium hobbyists. This species is part of the Halimedaceae family and is known for its distinctive segmented appearance, resembling a string of green coins or a cactus. Each segment is composed of calcified plates, which contribute to the rigidity of the algae and serve as a deterrent to herbivorous fish.

Care

The Halimeda Plant is relatively easy to care for in a reef aquarium setting. It requires moderate to high lighting to thrive and can benefit from the addition of calcium and other trace elements to the water to support its calcification process. It is important to ensure that the water flow is not too strong, as Halimeda incrassata can be dislodged or damaged by excessive currents.

Symbiosis

While Halimeda incrassata does not have any well-known symbiotic relationships akin to those seen in anemones or corals, it does play a role in the reef ecosystem by providing habitat and shelter for small invertebrates and fish. Its calcified structure can also contribute to the overall stability and structure of the reef.

Habitat

Halimeda incrassata is found in tropical and subtropical oceans around the world, typically in shallow reef environments. It is often seen growing on rocky substrates or within seagrass beds, where it can form dense meadows. These algae are an important part of the marine ecosystem, as they contribute to the formation of sediment and can influence the carbonate chemistry of the surrounding water.
