I was looking at getting a bamboo shrimp myself. It's true, they do like current, and enough suspended particulate matter for them to eat, so if your tank is pristine and crystal clear, they might not have enough to eat without extra feeding, which apparently can be done by squirting ground up flake nearby with a turkey baster.
They also like to climb up to where the current is strongest, so it would be a good idea to to provide some means for them to do this, eg some driftwood mid stream. I even thought about building something like this, although more for comedy value :)

Also bear in mind, if it can't find a strong current, it also might try and climb out of the tank altogether. Make sure your hood is secure
