Could be goniastrea. Call it a goniologyra.

It strongly resembles Platygyra pini. Platygyra and Goniastera are very similar, with the main difference that Platygyra does not have prominent columnella centres. Both require the same care. Good water movement, but no direct current on the coral. They produce tentacles at night and may sting surrounding corals, so keep an eye on it.

By the way, this is considered and LPS, not an SPS, therfore you asked on the wrong forum. Maybe someone on the LPS forum could be more exacting with an ID.
