any ideas to cause of death? Pregnant female guppy was found with a red belly on the side it was lying on.

tank parameters are normal except for low KH: 40 ppm
*Have not tested for ammonia, but I don't think that's the issue.*

The day before she died, the only male guppy in my tank also passed away. There were no visible clues so I automatically assumed old age as the cause.

There are only 2 other female guppies, 1 guppy fry in a breeding box, and 1 Cory catfish.

How old is this fish?

I'm guessing it's at least 1.5 years old.

All the other fish are OK ?. I think it may just be old age. The dark lines around the scales indicate to me that it is a mature fish.

Yup, the other fish are all fine. Thanks for helping!

It is not unusual to loose a pregnant fish, it puts a lot of stress on their bodies and the more times they have fry the more stress they have to deal with. Over the years I have lost several pregnant fish and the older they get the more chance of death. Sorry about your fish

It looked like it was pretty closed to giving birth before it died.
