Recognize this Acro?

[Baker]

So I picked up this acro colony a week or two ago and for the life of me I cannot get it to send out polyps. Ive tried putting it in high light/high flow, medium light/ high flow.... Well you get the picture. Is this a deep water acro, I googled 'deepwater acropora and a couple of pictures of this type came up. Is anyone familiar with this acro that could tell me a little about it? Any help is appreciated.
