Coral Suggestions for back wall/overflow

[Manda0597]

Hey y'all! I've got my 90 up and running and I think we are ready to dip our toes into corals finally! I would like to get one growing on the back glass and overflow that will spread out nicely. Any suggestions? I don't really like GSP from what I've seen. If you have it please show me! I was thinking either a mushroom Coral or Cyphastrea. Something hardy as it is our first time having corals! Pics of this being done would be great inspo as well

I have both Povona cactus and/or lithophyllon undulatum growing on overflows. Here's a pic of Povona cactus in one of my ssytems.

And here's Povona with Lithophyllon. As you can see the Lithophyllon is more aggressive. The pronounced circular growth of the Povona is also intriguing, most positions and locations that growth form won't be seen.
