i think it is A. spathulata maybe. but the price tag doesn't seem to match. From what i research A. spathulata is aussie coral.
i think is a millepora. and nvm on the tank raise thing, it is mariculture. Do you guys think it is possible to keep the coloration once is in a close system?
yea this pic is from my LFS. not sure about the coral at top right, didn't pay attention to it. Does RTN spread?
