Female guppy dying after birth

[bigben]

my past two female guppys have died within a week after giving birth. is this just normal with the stress or is there something you can do to prevent it? Thanks

It's quite common i'm afraid, they need a break from giving birth all the time, it takes it's toll on the fish, giving birth all the time decreases there lifespan, remove the male's from the tank, she will carry on having a few batches of fry as they can store sperm.
