That is not that strange. I have had clowns take to several different types of corals. Enjoy it while it lasts. Sadly, it is very likely that your flower pot coral will eventually waste away and die. As a newbie, I fell victim also. I was attracted to their cool look. Unfortunately, I wasn't aware that they are nearly impossible to keep. It is a shame that they are being sold at all. Who knows, maybe your flower pot will be the 'freak' and survive. I'm just reporting what I have read and what I have experienced.
