Spread of Green Star Polyps?

Yep, I must agree too! Briareum's most common form of reproduction is asexual, new polyps form from the original colony as it keeps reproducing it's purple or brown mat where new polyps sprout.
Just be careful with placement, as this polyp can spread like wild fire in ideal conditions. I have had success in propagating at least a dozen medium sized mats by simply placing unwanted or new frags of live rock beside the main colony.
Good Reefing!
