The Cactus Caulerpa macro grows from a "runner", a common name for the root like systems that grows along the substrate. The plants grow up from the runner. You can create multiple plants by removing the runner intact from your tank, clipping it in an area that is between two plants and planting the new runner to liverock or a different substrate.
Cactus Caulerpa makes an ideal piece for the display tank in addition to the sump/refugium. It will grow well under moderate to bright lighting.
