was wondering if anyone knew what coral this is???

[jepree]

so i purchased a coral as a "RIDGE/BLUE CORAL." as yet i have not found a picture on the internet as to IT looking like a ridge/blue coral. it actually looks more like a cup/turban coral but the polyps don't extend and i already have one i tried big als but they were well.....i'm not gonna say "stupid" even tho i want to so i'll say VERY VERY uninformative and not helpful at all!!!

can anyone please give me a proper id on this coral???
