For my science fair project, after picking through all the ideas you guys gave me, I decided on the "Do fry grow better on live or processed food experiment." So, my question to you is, what is some commercially available fry food? Feel free to list flakes, pellets, and liquid, as long as they're big enough for guppy fry! I also need live food. Same thing, needs to be small enough for guppies. Can be anything, but preferably relatively easy to culture. I'll take a few difficult ideas too. So, let me know what you got! Thanks!
