Zebra danios, leopard danios, weather loaches, and three spot gouramis are all exceptionally hardy. You don't need to "cycle" their tank since they can tolerate high temporary levels of ammonia and nitrite which spike in the first few days/weeks of a newly occupied aquarium. Just do normal maintenance and partial water changes.
