It is a Entacmaea quadricolor, commonly call BTA (Bubble Tipped Anemone). Care for all BTA are the same. In compare to SPS or LPS corals, bright, but not too bright light, LPS level. Low level of water movement near LPS. They like to live on the rock, hid their foot in crevices and reach out and up for light.
I don't know how experience you are. If you are inexperienced enough where you don't know what I am talking about then it is likely best for the anemone and for you not to get this anemone.
