goniopora

Hello, I recently got a this frag from a fellow reefer and have no idea what it is. I think it's sps and someone told me it's a type of goniopora but I can't find anything online that looks similar to this... The frag is about the size of a quarter and the polyps are super tiny. Any help would...

Hi.. as the title states can I place gonioporas next to each other or will they sting? I have a long polyp pink Goni and I want to get a red long polyp Goni to place next to it. Experience and/or feedback much appreciated. Regards, Shan H.
