bare bottom shrimp tank???

I don't see why it would be a problem if there was a sizable chunk of moss in there. It would make it a heck of a lot easier to catch the little buggers.
 
or even just on the sides for the moss walls, my shrimp spend alot of time on the moss walls i have on my tank sides. Its the only moss i have in the tank (cherry tank anyway). i like the painting the tank bottom black, or placing the tank on something black.
 
Mines not bare, just a thin layer of sand. but it's pretty much the same thing
