i was gonna buy some ghost shrimp and cray fish. are they gonna dig up the sand and make a mess?

i've got gravel in my tank and about 5 grass shrimp that move the gravel around somewhat to clean up but its may be different with sand.....but they are working out really nicely cleaning up and my p's havent ate them yet....well not all of them

Shrimp will not dig, and some crays do burrow. Set up some hiding places in your tank and they'll be fine.
