Question about flagfish eating habits?

I've got a 10 gallon unheated planted tank with 8 adult white cloud mountain minnows (and lots of snails...). Yesterday I found some Florida flagfish at PetCo, and I'd LOVE to get one for the 10g. I've got plenty of hair algae in there for them to munch on, too.

The only problem is that I've also got a ton of white cloud fry in the tank as well, since the adults spawn like rabid bunnies. The parents don't eat them, but will the flagfish? I could always move them to a separate tank, but they're doing great in the 10g, with plenty of infusoria and crushed up flakes to eat. The biggest fry are about 1/2" and look like little fish, with visible dorsal, pectoral and anal fins and an iridescent streak running down their sides. The smallest fry are tiny little new hatched wigglers clinging to the glass. I'll probably have more soon, too, since I watched yet another spawn tonight. They're all still small enough to be eaten, however. I was planning on adopting them out when they were big enough.

So will a flagfish eat them?
