Caulerpa Care Guide
Caulerpa prolifera · Saltwater algae
What Caulerpa look like
Flat, blade-like fronds on horizontal runners (stolons). Bright green color. Some species have grape-like (C. racemosa), feathery (C. taxifolia), or serrated leaf forms. Can reach 15+ cm tall.
Behavior & temperament
Fast-growing invasive macroalgae. Must be contained in a refugium as it will overgrow corals in the display. Can undergo 'sexual events' (sporulation) where it dissolves overnight, releasing toxins and crashing water quality.
Diet & feeding
Photosynthetic autotroph with high nutrient uptake capacity.
Behind the name
From Greek 'kaulos' (stem) and 'herpo' (to creep), referring to its creeping stolons.
Plan your tank
Check the numbers before you buy: tank volume, salinity, salt mix, water changes, and your ongoing care routine.
