These have been 'free' for over 2 years. I haven't hassled them to find out the state of their bases, but one has moved, about 9 months ago, to where it sits now. It's huge for what it is, but so are all the parent heads. The 'mama' coral has more heads than I can count---it's bigger than a basketball, and as soon as we get through the holidays I'm going to frag it because it's taking my rather small tank---and the heads are huge, over 2" across. Ditto the 'free' heads. So maybe there's a chance: frog and hammer grow well in this tank. I'd be really happy to have a few 'starts' that have a peculiar history in my tank.
