Well I decided to stop being lazy. I've snipped up all the dead tips on some of my SPS, I had been hoping they would overgrow the dead parts. Some have, but the one's who haven't had just been making the place ugly. So, snip snip. Some have been made into a small frag from a whole mini colony, others have been cut in half and left on rock.
When I removed one frag from the rock, I realized it had spread in a 2x3" area and has about 8-9 1/2" arms.. It did this while not even attempting to grow over it's dead tips.
So I was wrong, and wasted time waiting for something that's unlikely to happen.. Ah well, live and learn. Or learn from others mistakes!
So -- Pics. Of mostly nasty flubber just this once.
