What Nano Tank?

[Westwood]

I have a bowl with my shrimp in, but i really need a proper tank now for them.
So i have been looking for a nano tank with dimension less than 30x30x30cm so about 27 liters i think.
So any ideas?
Thanks
EDIT: By the way 30x30x30 is my maximum, but i will go smaller to about 15x15x15, so anything inbetween those dimensions

Here there are 3 nanos available, one 10 litres, one 20 litres and the last one 30 litres

And this is Fluval's special 30 litre shrimp tank
