the lfs guy said it was a fast grower, he had a big colony, and october sounds about right.
I almost didn't see it in his tank, in the back and not the best lit position, but as soon as i saw all the polyps were purple, i knew it was the one in your avatar. i had already paid for some zoas, but he offered to cut me a frag for a great price; he's got some great corals, including the purple bottlebrush, a large colony of that which he plans to frag up in a few months. im on that list.
