Very cool looking, I never see how fungia propagate before. Dinner plate plus size
, I have to pass on this one (not enough real estate :-[).
So is each one of those little guys on the wedge a baby?
Wonder how fast they grow.
I wasn't trying to scare anyone off by mentioning the adult size of this coral but that's what we must consider in our stocking, the adult sizes of animals.
Also, it'll probably need a sandbed.
This is a good time to thank Gresham and Reef Nutrition for producing some really excellent reef food and sponsoring the feeding of this tank.
Also thanks to Steve and New Alameda Aquatics for sponsoring the salt mix for this little endeavor.
And of course, Scott and Truvu for producing an excellent tank for my project.
This tank will be written up in future issues of my magazine and also on this site in the DIY forum.
Also, it'll probably need a sandbed.
Did you really say that 
Looks sweeeeeeeeet

I have never really done much with hard corals, but this looks an ok one. Looking in Julian Sprungs Quick ref it needs moderate to high lighting, pretty good flow and is reasonably hardy.
Thanks Dave, the more we all find out about these corals in advance, the better chance they have overall.
Based on the pictures I'm seeing and the parent skeleton size (extrapolated from the wedge we acquired), I'd say we're looking at dinner plate plus size adults.
