Hi all! I have an odd question. What are the best critters tocycle a tank with. I'm from the old school of thought, and basically, what ever is hardy will do it. So I've been told, however this time is different. I want to cycle a tank with critters that I would like to use as food items. I.e., shrimp, amphipods, saltwater guppies etc... Any suggestions, or am I way off into the left field bleachers.In the past I've used chromis, damsels, and have even tries 'pure' amonia. They all seem to work, but I was never totally satisfied with the results. Thanks for any help! Felix.
