Well, first off, you'll need a separate tank to raise the fry in. Second, you'll need brine shrimp eggs ( a lot of them), as well as a rotifer culture, and Nannochloropsis and Isochrysis phytoplankton(they sell these online as frozen, which is the most cost effective option). Check out MOFIB, which I think might have an account of how one person successfully raised their chromis' fry.

Do you have any pictures of the chromis and/or eggs? Are the fish doing parental care? I've not read about chromis breeding in a long time, so it would be cool to know this!
