The live rock is an anchoring place for corals, they don't "need" it to live aside from the filtration involved. If your new tank doesn't have any then I would highly suggest buying at least 20 lbs of dry rock from bulk reef supply and then doing a fishless cycle from there. The engineer goby or snowflake eel you have your heart set on will need some live rock.
