Ventricaria ventricosa, commonly known as Sea Pearl or Sailor's Eyeball, is a large single-celled green alga that resembles a translucent marble. It's a fascinating addition to the reef aquarium due to its unique appearance and ease of care. This alga is photosynthetic and requires moderate lighting to thrive. It can grow to the size of a small grape and is often seen rolling around on the substrate. Ventricaria is beneficial for nutrient export and can help in controlling nitrates and phosphates in the aquarium.
