Okay now, how do I get the little guys to eat!? I've gotten 2 out of 13 to take worm bits, but that is it. How long can they go without food at this point? I know it's only been a day, but they're so tiny I feel like they could drop dead any second. I have guppies but don't know how to offer them. Should I just leave a shallow dish with water and a couple? Does it matter if the dish is not transparent? What is the standard time for them to start eating?

I've already become attached to every single one of these guys. It would be terrible if I lost them to starvation. HELP, please.
