Just a bump, this tank will be a reality next week

Stealing some gravel from my tank at work to seed it and once it has cycled (fishless) i can begin the stocking.
So far I am thinking 2-4 angels. These would be the main attraction.
I really would love some fish that would school in the angels presence. Any suggestions?
And a cleanup crew, 2-3 pictus cats and maybe 2 bristle nose pleco's.
Any other good tank mates?
I decided on a black sand substrate for the bottom with lots of plants/hiding places via a
driftwood centerpiece of some sort and maybe a rocky buildup that offers hiding places and caves.
I picked up a hospital/quarantine tank while out at lunch today. Grabbed a 10G with heater/filter airstone and a small rock for a hiding place.
