Freebee Coral, wasn't planning on....

[Bumgrundle]

....introducing any coral for a year or so, but this came with my cleaner crew. Tank is only a month and a piece old, so I haven't even been looking at corals at all....don't want to be tempted. This is however a tank I plan on doing SPS/LPS down the road.
Can y'all tell me what species this is?
(The green one on the left is what I am discussing, the Pulsing Xenia was on some fuge seed junk a lfs gave me)

Ohh and proper placement in the tank, and waterflow?
Now it's in the middle of the tank and has direct flow med to high. (I move my powerheads every other day for some variance)

Alveopora sp. would be y thoughts. If so, place on sand bed.
