Just my opinion, but to be consistent with the healthy store image you need to go all captive propagated fish/corals. Aquacultured rock should also be in the mix. Then to take it to the next step all equipment could be energy efficient and have a minimal carbon footprint.
Just to prove I'm serious my latest tank has 12 of 15 corals that are captive propagated (the other three were gotten from LFSs with frag trades), fish are ORA captive bred, and all the equipment running the 33.9 gallon tank uses less electricity than a 100 watt light bulb. 20# of rock is cured base rock with only 5# of real live rock (which I already owned). Sadly, captive bred CUCs are hard to come by so I had to get most of it wild caught.
Just a thought to raise the bar for you cherubfish
