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.

Available Options

1-2" Bubble Berry Frag

Smaller cutting with established vesicle clusters and active branching. Ideal for grow-out or adding to a macro display with room to develop. A rare opportunity to acquire this species at an accessible entry size.

2-4" Bubble Berry Frag

Larger, more developed cutting with fuller vesicle clusters and branching. More immediate visual impact — the full Bubble Berry effect right from the start. Best choice for display tanks where presence and color matter from day one.

Care Information

Lighting Moderate to High
Water Flow Low to Moderate, gentle and indirect
Placement Mid to upper rockwork or frag rack — display tank or refugium
Care Level Moderate — requires stable parameters
Growth Rate Moderate — slow to establish, then steady
Nutrient Export Moderate nitrate and phosphate uptake

Special Considerations

Bubble Berry is more delicate than most macroalgae and benefits from stable, consistent water parameters. Avoid strong direct flow which can damage the vesicles and cause tissue loss. This species can be sensitive to sudden parameter swings — acclimate carefully on arrival. Keep away from aggressive herbivores such as urchins and tangs that may graze on or damage the delicate vesicle structures. Handle with care during placement to avoid puncturing the vesicles.

Due to natural variation, the specimen you receive may vary slightly in vesicle density, branching structure, coloration, and size. Photographs are representative examples.

Individual specimens may display differences depending on lighting, flow, and tank conditions. Some vesicle loss during shipping is normal and the specimen will recover under stable conditions.

Size and appearance are provided as general guidelines and may vary slightly from the specimen received.
