As far as beneficial bacteria goes I put a few plants from my established 56 gallon in it. It helped fill some space but also provided something to seed the water.
So you think I should just go ahead and get some little shrimpies to amuse me and bring joy to my life as long as I do 50% water changes twice a week for a month? :D :D
