congrats
first off, with fry you'll need to keep your water very, very clean, i'd suggest doing at least one extra
water change per week. you can feed them flake food that's been crushed into a fine powder, and when they get a bit larger you can feed frozen baby
brine shrimp. i would keep them separated until they're big enough to A. not get eaten and B. not get sucked in by the filter intake. personally i don't breed fish but there are lots of breeders on this site that can give you more specific information.
