Considering you are cycling a 12 gallon FOWLR
tank without a skimmer you could just use 1/2 a shrimp or a small one... let it decompose, and only worry about doing a water change at the very end of the cycle.
You may still want to put in some live rock (or base rock) while it cycles to let it build up bacteria on and in the rocks pores. If the live rock you eventually get is uncured it could make it's own ammonia spike and mini cycle (especially because your tank is small and skimmerless). You may have an easier time adding it in during your cycle just in case it causes you any brief issues later. Not a necessary step, it's just standard practice.
