Busy week for the reef! Picked up this frag yesterday which is supposed to be some sort of efflo, although the piece it was taken from was just sort of ball-shaped. It had been sold to the LFS as an efflo and had died back and re grown twice in the 8 months or so they had it. It was still recovering from the last die back but I convinced them to cut off one of the live patches. It only cost me $16 so it was worth the risk. So far it is just greenish (which looks emerald under actinic, and purple in my photo) with the newer growth brighter green with darker (reddish?) polyps. Polyp extension seems pretty decent where I have it. We will see what it does.
