Xen, those are the exact two tanks I mentioned above as my inspiration.
Somewhat; Crypts would look great, and I find myself leaning towards shrimp over fish usually. I'll look into those breeds, fish and shrimp could all exist great here.
The more thinking I do, the more I plan on leaning towards a low tech setup with a powerful filter, lots of plants underwater and above, and a light hanging either from the ceiling or via a frame or something. Maybe only Excel and Ferts, to bypass having to get a nice CO2 setup. Still pondering for now.....
