Which one produces more fry?

[J0hnny]

I am in desperate of wanting fry, so i am going to get some live bearers. A long time ago i used to have a female swordtail that gave birth to 50 babies, 20 survived. I gave the rest away and kept 2 male swords... so hopefully i can get a couple more.

i dont know which, but try my plan, in my tank i have some mollies and some plattys and some guppys, and this is a newish tank so in the near future i will be in undated with fry
