Sorry to hear that.
It's quite common, unfortunately. Even systems that are created specifically for these NPS often have difficulty keeping them in good health long-term (let alone having them grow and reproduce).
From all I've read over the decades, the best chance of success in a typical reef aquarium would be with a very mature thriving system (at least a few years old) that has lots of smaller organisms regularly reproducing as well as regular feedings plus frequent detritus stirring.
