Don't move the live rock, just get a couple PVC
elbows for them to hide in. As for your your water peramiters, use water from your display to setup the tank, make sure you have pleanty of salt water mixed/mixing in 5 gal
buckets for water changes. If your peramiters start to go up, do frequent water changes. As for the Mandarin Goby, i have been informed - correct me if im wrong - if you feed Zooplankton it has pods
in it. But im not sure about that one.
