Fathead Dendros (Dendrophyllia fistula)?

[Marten]

I was sold these two frags as Fathead Dendros. They don't look like any Fatheads Dendros that I have seen before so I'm trying to get more opinions before I reach out to the vendor.

 

[Ron Reefman]

They look like typical closed up Dendros to me. Maybe they'll look different when the polyp out?

 

[Will Wohlers]

That's a common sun coral not a dendrophyllia unfortunately

 

[Gaufl]

Yes, they are Tubastraea (Sun coral) not Dendrophyllia.

Greetings,

A closed up dendro should look more like this
