ID please

If this picture isn't good enough, I'll try to get a video of it. The polyps are very active, when a pulse of water hits it, you can see it move across the coral in a wave like motion.
The way it has encrusted the frag rack has me a little worried about mounting it to my rocks. I'm afraid it could end up being problematic.

Short video.

Is it just a green milli with no stalks yet?

I can't even tell if it is an Acropora, No way to tell what species it is. What does it look like when the polyps are retracted?

looks like a very young milli

This is as closed as I could get them. I'm guessing the coral is to young and not enough structure for a proper identification.

There are no corallites like A. millepora. They could grow out later maybe. Could be any of the fuzzy Acros like prostrata, convexa, spicifera, etc.
