Your New Guppy Fry
Good morning Adw...
You feed the fry the same thing you feed the adults. But, put some of the dry food between two large pieces of waxed paper and crush the food with a rolling pin.
If you have the fry separated, then keep them in their enclosure and feed as often as you can for a week. After that, they'll be ready for the main tank.
Start feeding the adults more often too. I have several large tanks of Fancy Guppies, but have never separated the fry from the adults. Anyway, it's been my experience that well fed adult Guppies seldom bother the fry.
