Here's Our Thursday ROUNDUP! Why are most round Corals best placed in the sand?

[Corals.com]

There's just something about a round coral that adds an awesome look to your tank! We have a great selection of round coral colonies on the site. Ever notice that most "round" corals are best placed in the sand bed of your tank? That goes for Scolymia, Fungia, Acanthophyllia, Trachyphyllia and Cynarina! Our observation is that all of these corals need the support for their flesh to extend out and be supported. If anyone has another observation, feel free to chime in! Can you think of any exceptions!? Here's our Thursday ROUNDUP currently available at Corals.com!
