Im trying to get some ideas together for stocking my 36g bowfront. Ive decided id like to try large schools rather than a few larger fish. So far im thinking 12 to 15 albino cory cats for my bottom dwellers, 8 to 10 silver hatchets for my top dwellers and im still trying to figure out what would make for a compatible middle swimming fish.
Id like to try densions barb as they're quite pretty but they're just too large. Any suggestions? My gravel is a mix of black, reddish orange and deep red. I thought the albino corys would be an excellent contrast for my substrate and thought maybe something with red or orange would be striking as middle dwelling fish. Cherry barbs maybe?
Denison barb rather. Is gravel too rough for cory cats?
A school of 10 Harlequin rasboras would go well mid-level.
Your gravel will be ok for the cory's.

Please remember; every keystroke has a consequence.
I wouldn't consider Denison Barb, Puntius denisonii, as they attain close to 4 inches and a group of 6+ would be a bit crowded in a 36g tank. Plus, they are riverine fish, liking some water flow, and this counters hatchetfish.
The rasbora suggested by Strider are fine. Other mid-dwelling shoaling fish are some of the tetra, especially ones like Rosy Tetra, Roberti Tetra, Black or Red Phantom Tetra, etc. The Pretty or Garnet Tetra (Hemigrammus pulcher) is a lovely fish that remains almost mid-tank, a bit higher than the others mentioned here.
What are your water parameters, meaning GH and pH? This could affect fish species under consideration.
On the gravel, if it is at all sharp, forget corys unless you change it. Corys are fine over sand, and fine gravel. Having had both, I would go with sand if possible, but as long as what you have it smooth it will probably work.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
+ 1 to striders suggestion of Harleys, you can never go wrong them, you could also do Five banded barbs, all the beauty of Tiger barbs without the size and disposition, they swim a little closer to the bottom however. Any of Byrons tetra ideas would work, I'll throw one more "old favorite" in there, it being the Flame or Von rio tetra that stays in your "red or orange" catagory.
Your Cory idea would work as long as your substrate is not too course or rough as was mentioned.
You have the makings of an attractive tank, what with the silver hatchets on top and all.
