Common name: Mermaid's Wine Glass

General information

Acetabularia crenulata, commonly known as the Mermaid's Wine Glass, is a distinctive and fascinating species of green algae found in shallow, warm marine environments. It is characterized by its unique umbrella-like cap and slender stalk, resembling a miniature wine glass. This species is not only a beautiful addition to the reef aquarium but also serves as an indicator of good water quality due to its sensitivity to pollutants.

Care

Caring for Acetabularia crenulata requires a well-lit aquarium with moderate water flow to mimic its natural habitat. It thrives in environments with strong lighting, which is essential for photosynthesis. Hobbyists should maintain stable water parameters and provide a substrate rich in calcium for optimal growth. Regular water changes and nutrient control are crucial to prevent the overgrowth of competing algae.

Symbiosis

While Acetabularia crenulata does not engage in symbiosis with animals, it plays a vital role in the ecosystem by producing oxygen and providing a microhabitat for small invertebrates and microorganisms. Its structure offers shelter and breeding grounds for these tiny creatures, enhancing biodiversity within the aquarium.

Habitat

Mermaid's Wine Glass is typically found in the Caribbean Sea and adjacent Atlantic waters. It grows on hard substrates in shallow waters where sunlight can easily penetrate, often forming dense meadows that contribute to the complexity and productivity of the reef ecosystem.
