Died. They had seem to be doing well too. We actually had 3 survive the winter which we've had little luck with being novice pond keepers. I hadn't been able to get any plants yet, I usually buy the floating variety, because there weren't any available yet. I'm gonna drain it almost dry, refill and condition it and see how it goes.
Have you run any water quality tests on it? Ammonia, Nitrates, pH?
