This was July 2011. I transferred my female guppy from my 20 gallon aquarium to a one gallon aquarium that had a lot of covering on the bottom and had floating plants for the baby fry to hide. Once the mama had her babies, I transferred her back to the 20 gallon aquarium. Of the 40 babies that were born, 5 survived. The 5 babies that survived are now in my Tetris, half moon, 10 gallon aquarium.
