What kind of Coral is this???

Bought this beautiful coral a week ago, the store owner couldn't remember the name of it, I figured searching online I would easily find it but can't find anything like it! any ideas? Also is has tripled in size since I got it, the lights at the store where not as good as mine.

 

looks like a open brain to me

 

Looks like it could be a welso or a trachy brain.

 

First off, you really shouldn't buy any coral until you have researched first so you know if you will be able to accomodate the coral. Look here;
Coral Identification Photos - Marine Aquarium Reference

 

Trachyphyllia radiata would be my guess...

 

That's what it is. (ID'ing these properly can be confusing because they were recategorized a number of years ago. They used to be labeled as Wellsophyllia radiata. As a result, on the Internet, you can find them labeled as either)

 

Which explains why I was getting both of them as results when searching for them!

Thanks for the clarification!

 

Thanks guys, and I knew it was close to an open brain and had the right reef setup for it, just couldn't quite find the right name for it.
