Is this a Wellsophyllia?

[Broberg]

Hello, i bought this coral yesterday and got told it was a wellsophyllia, i never heard about that coral before but i bought it as it was just beautiful. But when i look at it i think it looks a lot like a trachy. Can anyone help defining what it is so i take care for it correctly? :)
It's around 16 cm in diameter.

They are both synonymous with the Trachyphyllia genus, so a trachy and a wellso are the same coral.
