Green Sea Grapes

Care Summary

Green Sea Grapes (Caulerpa racemosa) produces clusters of small spherical fronds on creeping runners, resembling tiny bunches of grapes. It is a popular display and refugium macroalgae that grows quickly under moderate to high lighting. Like all Caulerpa, it can go sexual — watch for pale, mushy fronds and remove immediately. Tangs and rabbitfish will readily graze on it, helping keep growth in check. Excellent nutrient exporter when actively growing. Trim runners to prevent it from spreading over corals.
