Yep, growth form and polyps are a match for encrusting monti. Harder to tell when it was a wee frag, but now that's it's grown out a bit it looks like a lot of other Montipora Undatas.

A month or so ago an Arbacia Punctulata urchin muched the right side because it was in his path, but it grew back pretty quickly.
