SilverDak, if you are going to pull the trigger and put something in there I know I cannot stop you. If you really want to make sure though, ghost feed the tank for a few days. Put some fish food in there, just a pinch, each day for 3 days running. Test the ammonia and nitrites and nitrates every day to see what is happening. If your bio filtration is ready to handle some critters you will not see a reading on the ammonia and nitrates that you now show as zero. If however you see jumps in any values your tank is not cycled and should not have any life added yet.
My opinion is that you should not add any life to this tank for another 3 weeks minimum, but that is just my opinon.
