Is there a centerpiece-type LPS that's safest for nippers?

I have a flame angel and a bicolor blenny, and neither are getting rehomed (one is my son's favorite fish, and the other is my wife's favorite fish). Between the two of them, they've killed a couple trachy's that I've tried. I'm curious if anyone has an evidence-based opinion on another type of centerpiece worthy LPS that I might be more successful with? My euphyllia are all doing great, so they don't kill EVERY LPS I put in the tank. I love the look of bubble corals and cynarina, but don't want to try keeping one if it's horrible idea. Open to other ideas also. Thanks!

Elegance corals should be fine and make great show pieces/center pieces.
