i hadnt thought about it, but an african aro would be awesome in there with your gars. that looks way more primitive than other aros and looks almost more ancient than the gars.
not sure about african aro, but here's what i'm working on: 2/3xcubans, 2/3xtropicals, 1 gator(for a little bit), maybe 1 orino. im thinking of 2cubans 3trops.
i was looking for a 20" african bony tongue aka african arowana but couldn't find one and ended up with 3 orinos
