What kind of shrimp? None of the ones I've kept(rcs,crs,amano,bamboo) have ever had any interest in cichlid stones. They rather hangout on plants or driftwood.
I'm scaping for RCS. I have a betta who is currently living with a few ghost shrimp as a test run. So far everyone is alive and mostly happy I don't want to buy any REAL shrimp until my plants fill in.
