What is this? It's pretty!

So, we've had this for a very long time, but I'm still not entirely sure what it is exactly.
It's gone through a lot of color change, but I really love the nice blue color. It can look more brown if positioned wrong though, just because of the way the light reflects off it, which is interesting. Also, when I picked it up to take this picture whatever reaction it had seemed to make it more brown as well.

Sorry it's so fuzzy, It was the best picture I could get. I had to pick it up from its little nook and bring it closer to the acrylic to take the picture (so yes, it's floating haha). In focus, each of the little ridges has even more texture, sort of like what I've seen called circuit board coral.
It has been looking healthy as long as I've had it, but not much growth at all in over a year.

Thanks for your help!

Check out some pictures for Psammacora. Very well could be that but the picture obviously isn't clear enough.

hmm that looks really close but not quite.
those seem to have defined polyps while this is more ridged very close up... sort of like a circuit board.
i'll try to get some better pics soon.

Psammacora really don't. Investigate P. Verrilli, P. Profundacella, P. Haimeana, P. Vaughani or for the real circuit board look P. Explanulata.

Psammocora Vaughani seems to be the best bet.
I'm not entirely sure, because I couldn't find many pictures, but it seems pretty darn close.

Thanks for the help!
