Soooo those two I carefully seperate with a surgeon type blade and they both lived and are still alive, I think they 'TWIN' gene for guppies comes from the father bc another of my females bred to the same male had joined twins this afternoon, I took a gamble and up them in 10 gallon NEWBORN tank. I move fry to 30 gallon once they are able swim and hide when I try and suck out with turkey Baster...that's how I get newborns outta large tank as well. Anyways the NEW twins have separated on their own and are alive and kicken it with all my other 3 week/month and under babies!
