When the babies are newly free swimming I feed Hikari first bites. Once they get a bit bigger I feed them some other powder food I have no idea what it is as I won it through a contest on another forum. I also feed decapsed brine shrimp eggs when they are a bit older. I got some earthworm flake, beef heart flake, egg flake,and spirulina that I grind up super fine and feed that to the bigger babies. Oh I also feed little babies frozen baby brine shrimp.
