Why are we even encouraging cycling with living animals anyways, clownfish4? Most people on this board seriously discourage it and consider it the worst possible way of attempting to cycle. I would take the shrimp out and return them to the LFS...they may even hold them for you. I would then attempt to cycle with live rock or frozen shrimp. After your cycle is finished then re-introduce the inverts. Your clownfish probably died as a result of the cycling process as ammonia levels, which are highly toxic, are simply too stressful to survive in. Why try to cycle again with living fish if you've already witnessed the result once. Not only is it a waste of money, but it is cruel and, as you have seen, inefficient. Good luck...I hope everything goes well!
