I'm a little confused. So - your cardinal is now dead... the one that was alive a couple days ago? And you say you just cycled your tank again "...as soon as the cardinal died..." which would mean just within the last day or two.
Just so we're all talking the same talk - cycling is when you introduce an ammonia source, and establish a population of bacteria to convert the ammonia to nitrites, and the nitrites to nitrates. It's something you don't need to do multiple times. I have a feeling that you mean water changes, and not cycling? Which brings us back to the question of whether or not the tank has been cycled? Test results for ammonia and nitrites would give us the answer...
