sps or lps?

[toytech]

I picked up this frag of a local and i was thinking it was hydnophora but now that ive looked up more pics of hydnophora im not convinced . It was growing with a flat branching structure not the thicker branches ive seen on the hydnophora , and now thats its aclimatised and is showing polyp extension the polyps are very small and short , looks just like the polyps on my montis . So if its not hydnophora is it a type of monti or is it something else ?
