Red Bubble Algae

Care Summary

Red Bubble Algae (Botryocladia species) forms clusters of small, deep red to maroon spherical bubbles on rocks and surfaces. Unlike green bubble algae (Valonia), it is not a nuisance — it grows slowly and remains in contained clusters. It is a striking display macroalgae that requires no special care beyond moderate lighting and flow. Generally left alone by herbivores. Does not spread aggressively. One of the more desirable 'accidental' additions to a reef tank.
