About this item
Bubble Berry Macroalgae
Bubble Berry Macroalgae (Coelarthrum sp.), also widely known in the hobby as String of Pearls, is one of the rarest and most visually extraordinary macroalgae you can keep in a saltwater system. Its defining feature is immediately unmistakable — clusters of perfectly rounded, translucent red and pink vesicles that balloon outward from slender branching stems like bunches of glossy berries suspended in water. Under reef lighting, the deep crimson and rose tones take on a luminous, almost jewel-like quality that makes it one of the most photographed macroalgae in the hobby.
These bubble-like structures are gas-filled vesicles — a natural adaptation that gives the algae buoyancy and its signature appearance. No other macroalgae looks remotely like it, and healthy, well-grown specimens are genuinely rare — making this one of the most sought-after and collectible macroalgae available to reef hobbyists worldwide.
Beyond its extraordinary appearance, Bubble Berry is a functional addition to any system — actively exporting nitrates and phosphates while adding a pop of deep red that complements both coral-heavy reef displays and dedicated macroalgae tanks equally well. It is a premium specimen that rewards careful placement and stable conditions with truly spectacular results.
