What kind of clowns? Is this going to be a long term arrangement?
Some more aggressive clowns will beat the Elegance coral to death!
I know none of this was by design, but Skunk Clowns or Seabaes would be a better choices than say Tomato Clowns... IMOH
Edit: Monitor this arrangement!
I've found the Elegance is a temperamental coral to begin with. At the first sign of continued retraction in the coral, I'd move to plan B
Second suggestion would be to come up with a viable "Plan B"
