1.5 y/o acro frag

[dbenyo]

I got this coral as a little 1/2 inch nub 1.5 years ago. It was green and did nothing for a very long time. It plated over the plug and then sat at that stage for months. All of a sudden over the past few weeks it is sprouting up all these purple-ish tips... Any idea what this could be?

Hard to say those corallites look similar to many different Acropora species that could all potentially be those colors. It's too small for IDing now. Let it grow out some more.
