Sand is one of the few area I don't agree with zoidburg on. Buffering substrates take out some variables and guess work (maintaining parameters), but CRS are far more hardy than people give them credit for.
Having said that, I agree that keeping proper, stable parameters in that small of a tank long term is going to be near impossible. I'm all for experiments, but that isn't one I'd bother with.
Edit: I think cherries would be fine as they are a little less specific on parameters and allow for a wider range of "mistakes"
