Platygyra question

[Nihilus]

I traded in some frags at the LFS for a small frag of this yesterday. It's about 1.5" x 1.5" and pretty flat. I don't really have any room on my rocks to place this piece so it's on the sand bed for now. Assuming conditions are right, will this thing continue to grow on the sand bed or do I need to buy a small rock at the LFS and epoxy it to that? It would be great f it would continue to spread, but I'm just not sure. Thanks. :)

Mine hasn't spread at all. I've had it for a few months now. I was actually going to put it on a rock. I think they prefer that.

Ok thanks. :)

The next time I'm at the LFS I'll search through the live rock bin for a suitable rock to epoxy it to.
