I have a few guppies in my community tank, and I had a very pregnant female die. No signs of being picked on or attacked, but her tummy was red. Its been two weeks and the tank is very healthy with no more fish loss. Could it be she died in childbirth??? She was a second generation guppy and very pretty. Auuuggg! I was so sad when she died.... anyone else have a guppy die in child birth??
