it's easier to pull off of glass & fricks CD cases than it is rock.
& it can smother the good stuff. even with a thriving fuge
full of chaeto & C. serrulata & halimeda in the reef, it still
grows. i wish i had gotten a pic of a protopalythoa polyp
racing to outcompete this stuff. the wafer grew around the
polyp, the polyp released from the rock & climbed the tube of
wafer created. it was about 4" tall before it fell of the rock.
it will make shrooms n' such bail from the rock to get away.
those that can't run, get overrun. i thought it looked cool to
when it started too, kinda like a monti cap without the polyps.
that was a decision i regret (still fighting the stuff).
