Guppies not having many babies

[Roryn1]

Is it normal for all your female guppuies to have 8 to 15 babies? I used to get 30 in one time and now I think they went on strike!
Why arn't they have 30 babies like they used to?(and aren't they susposed to?)

well they dont always have alot. Maybe they released most of the sperm in them,a nd there was only a little left to make new babies.

Possibilities

1. Mom got hungry
2. There was more then one adult fish in the tank
3. They're so small you can't see all the ones that died for what ever reason
4. The sperm count is getting low
5. She's still pregnant and waits for a wile before she is willing to let out more.
