Naw, hon - you've GOT the bacteria! That's what the cycle is all about - getting a colony of bacteria into the tank and established enough to clear the water of toxins. But the bacteria need to eat to stay alive, and they eat ammonia, which is created by waste, which is created by critters - also dying or rotting bits of food and plants, etc. . . I've never tried to keep a cycle up without a creature before, and though I know it IS possible, I don't know how - or how much stuff (like food) you would have to add to do so. Do you have a test kit? It could be a very interesting experiment!
