A couple years ago I had a group of fire belly toads. They lead a very happy life and were constantly croaking and jumping on eachother (unfortunately they were all males and the store I got them from didn't have a single female). I was happy and had many hopes for the toads. But then, so spontaneously one toad bit the dust I had a rather hectic schedule and coudn't clean out the aquarium. Two days later all the rest of them died at the same time, it seemed like it happened in mid action, like the toads were just swimming along and then bang, they froze into their positions forever. Their spontaneous death has troubled me for the past few years and kept me from buying more, though I was very nearly able to breed them the first time. If knew what happened and how to prevent it I might get a few more of these animals and start over.
