sps ID please

Well, from what you have said I am positive it's a montipora, however, I'm pretty convinced that's not a m. undata. The two things that give that away are:

- the growth edge: m. undata has a smoother growth edge. Granted this can change depending on flow conditions but it general yours is too "gnarly" to be undata.

-The verrucae are too shallow and the corralites are too even and regular and are not fused into ridges, which is one of the identifying features of undata (and m. danae for that matter, which is commonly confused for undata)

Most of the time when you find picture of m. undata on the net, it's not actually undata... just kinda looks like it or they're really just making their best guess.

Montipora are probably the hardest to ID as there is so much variation not just within the species but with external stresses as well. And, without a geographical location it's almost impossible. You might have to wait for it to grow up a bit and see what it does or just settle with the fact that it's a sexy mystery monti. Or you can send me a frag and I can "take a closer look" .
