Good point, acclimated is the wrong word. However, would like one that is eating something and functioning in captivity. I've found it's very tough to recover unhealthy fish that don't eat right after hitting the tanks in the US.
I've had a lot of challenges with simply obtaining a healthy regal at a small size. I've become more interested lately from following this chain and seeing folks obtaining healthy yellow/orange belly juvis from common sources like LA, DD, LFS, etc.
I live in Atlanta and I never see healthy juvi regals at LFS. I come across 4"+ ones though. I'm sure most are snagged by hobbyists who don't know what they're getting into in terms of acclimating these fish and placing them in a tank where they wont get dominated. Very shy fish at first.
