Got this from $5 bin at LFS. It is very small just under 1/2 inch frag. Need to know what kind it is so that I can place it properly in the tank. Currently it is on the sand bed. I have seen no change in its appearance since I got it three days back.
First pic is with flash the next is without.

That looks like an Acanthastrea bowerbankii, probably worth about 10x what you paid for it, great find!

Cool thanks! So bottom / middle placement with moderate current ?

Bottom placement with low/moderate flow.
