Question about Cynarina lacrymalis (Button) Coral

[Lukey2018]

Hey everyone,

I'm wondering if anyone knows how big Cynarina lacrymalis coral can get? I have one that, while fully extended is approx. 20cm in diameter. I'm Just trying to find information on how large they can get.

Well here is a pic of it almost fully extended. It's hard to get scale perhaps, but I can say it's definitely in excess of 15cm.
