i have them in my main tank as i dont have anywhere else for the fry in that tank i have 3 full grown guppys 3 platies 2 plecos 1 albino cat female guppy had +40 fry what are the odds 10 of them survive (hypothesis)
If you don't have another tank get a breeder net to hang into the tank and transfer the guppy fry into there. I think all of the fish in your tank would snack on a few guppy fry so I would get the breeding net ASAP
