Of course! I mainly feed them brine shrimp, just recently got them to eat bloodworms.
@Gator; Don't worry, I already have a plan for that. I recently ordered one of those livebearer containers that have mesh halfway through them. If I ever notice one of the females is pregnant, I will move her into the container, though I've never done anything like this, so let me know if there's a flaw to this plan.
