Bubble Algae Care Guide
Valonia ventricosa · Saltwater algae
What Bubble Algae look like
Spherical, glossy dark green bubbles 1–4 cm in diameter, often growing in clusters on live rock. Surface is smooth and slightly translucent. Single-celled organisms — among the largest single cells known.
Behavior & temperament
Nuisance algae in reef tanks. Each bubble is a single cell containing thousands of reproductive spores. Popping a bubble releases spores, causing rapid spread. Must be removed whole without rupturing.
Behind the name
From Latin 'valonia' referring to the genus, and 'ventricosa' meaning swollen or inflated.
Plan your tank
Check the numbers before you buy: tank volume, salinity, salt mix, water changes, and your ongoing care routine.
