8 peppered corys: Cool water species of Cory, but adaptable.
albino BN pleco: One is fine in this size tank, but not enough room for more. No other algae eaters. Are you going to find the long finned form?
4 already paired GBR's: With plenty of hiding places 2 pair ought to be OK. They need warmer temps for breeding, not compatible with Pepper Cories. Also, Cories do not seem to respect the territories of Rams, and there could be some problems.
10 or so cardinals: Warm water fish. Compatible with the Rams. Go for more than 10.
or neons: Cooler water fish than the Cardinals, compatible with the Cories. Do not get both Cards and Neons, but whichever you get, get plenty of them.
zebra danios: Cooler water fish, and can harass the others. I like the long finned Leopard ones. The long fins makes them swim a bit slower, so they cannot keep pestering the others. They tend to swim higher in the tank than the Tetras. I would not do more than one school. Cards... or Neons... or Danios. Pick one species
dwarf gourami: Just one. They are territorial toward other Anabantoids. Nice for some color at the top of the tank. Warm water fish.
otos: Not with the Bristle nose. Pick one or the other species. Both are good algae eaters, but there is not going to be enough food for both. Up to half a dozen Otos, or 1 ABN.
Don't know about the shrimp. Could end up on the menu of any of the larger fish (Rams, Gourami)
I would end up like this:
6 Otos, 20 Cards, 4 Rams.
