Common name: Bubble Algae

Scientific name: Valoniaceae

Valoniaceae is a family of green algae, commonly known as Bubble Algae or Sailor's Eyeballs, found in marine environments. These algae are characterized by their distinctive, large, spherical cells that can form dense clusters. They are often seen in reef tanks, where they can become invasive if not controlled. While some aquarists appreciate their unique appearance, they can overshadow other organisms and compete for nutrients and space. Regular maintenance and manual removal are recommended to keep their growth in check.
