There's not a lot out there on them but here's my knowledge.
Key things for them, cold water, flowing water, high oxygen water. They also appreciate about as much plant matter as you can jam in there. With a tank like that you don't have room for much, I'd be looking at the 30-60 litre range if possible. However, if your heart is set on that tank, you will need to keep it in a cool spot, make sure you have a bit of moss for them and perhaps even add an airstone.
I'm looking at catching some shrimp in the next couple of weeks, they're great fun to watch
