Hmmm that's about 10 US gallons... In a BiUbe, the big problem you encounter is that because it's taller than it is wide, there isn't a lot of bottom space for fish to chart out their territories. Not to mention there is a reduced surface area.
For this reason, I suggest a very light stocking scheme, with non-energetic fish (eg danios, etc.)
A shrimp tank, or a lone betta and a snail would be good choices. Maybe a honey gourami. But honestly, the shape of this aquarium is going to make it really hard to work with.
