Genus
Common name: Bubble Algae
Scientific name: Valonia
Valonia, commonly known as Bubble Algae or Sailor's Eyeballs, is a genus of green algae found in marine environments worldwide. These algae are known for their distinctive, large, spherical bladders that can grow up to several centimeters in diameter. They are often found attached to substrates in the reef tank, such as rocks or coral skeletons. While they can add a unique aesthetic to an aquarium, they can also become invasive if not managed properly. Hobbyists should monitor their growth and remove excess algae manually to prevent overpopulation.
