I killed a very large plate coral... but it's progeny live on! These are no larger than a pencil eraser. And there's a few more about 2 mm across. That's why I listen to my wife, her idea to leave the "dead" coral in the tank.
That was a great call by my wife... I was all I don't want to see it feeling like c@#p because I'd killed it plan ... completely her call to keep it in the new set up. Strangely... first time in 15 years I've been wrong.
