I have to say, I have spent hundreds of hours diving on coral reefs and have never seen a "minimalist" reef. To me a beautiful reef tank is one that is aquascaped to met the needs of the inhabitants. A minimalist scaped aquarium with lots of fish is not a natural environment and to my eye looks stressful to the inhabitants.
I have always liked Centropyge angels. In the wild, if you are lucky to see one, they rarely stray from their territory of hiding places. If I have a Centropyge in a tank I don't expect to see it but for fleeting glances. They should be in and out of coral hiding spots constantly picking. They can't do that in a minimalist scape. Even large angels like a cave. Tangs need lots of swimming area but they also need a large surface area to graze. I have had fat and happy Mandarins that show up just in the evenings as they often do in the wild.
A beautiful healthy coral REEF tank should be just that, a thriving reef. That in its self is a work of art. If you want a piece of decorative art in your living room get a piece of sculpture
