Well I love Uaru! Need a bit higher temp and at least when young need to be in groups, but they have great personality and looks. Maybe I have just gotten lucky, but all the GTs I have had weren't terrors at all. I'd be comfortable putting them in a tank like that. This tank would also open up have Syns as well, because IME they are pretty peaceful for a CA, and though they don't have tons of personality they are just gorgeous.
