From my earliest memories as a kid charlie has always had lots and lots of orange australe. I remember as a kid going on about this new species or that new species and Charlie's response was: 'you can always sell orange australe'. Turns out he was right about that.
Charlie was breeding cardinals and congo tetras before I had my first goldfish and in my youth I remember tanks full of emperor tetras, so it was a joy to see the black emperor, which I'd never seen before, during this visit.
