this may be slightly off topic but once, I had a guppy that was having a real hard time passing her babies (only 3 in like, 8 hours) she was flipping around everywhere, almost out of the water. When I finally sat down to watch her, she all of the sudden tuned yellow (she was silver) and died all within a few minuites. Me and my roomate stood there in shock, and then after a few minutes, decided to scoop her up in a shallow pan, and give her a c-section. It actually worked, and I still have babies from that batch.
