I would recommend Pygmy cories, as sterbai and pandas won't have as much swimming area, as its a tall and not a long. If your looking for color you could do a pair of darters, they are extremely colorful, and are bottom dwellers, but they start off with only eating live food, but you can train the to take pellets and flakes. And they also need well-oxygenated water, so you would need a powerhead. If you go with Pygmy cories, I would recommend getting endlers as they are also small and colorful, or a school of CPDs
