Breeding is similar to other haps and peacocks. Where are they in the process? Have they spawned for you? Fry typically become free swimming around 14 days, give or take, depending on tank conditions, especially temps.
Occasionally I set up a maternity tank to for the female and let her spit the fry at her leisure. In this situation she may go a few days and let them out then gather them back, like when someone walks by, etc. Can interesting to watch this process. More often I strip about 14 days after spawn or a little thereafter. I feed hap/peacock fry with crushed up foods such as freeze dried brine shrimp, NLS or Omega One flake, or HBH soft pellets (your choice of flake might be different). Freeze dried brine shrimp and the soft pellets are both especially easy to make virtually powder size grains to feed the fry with.
Often I'll initially put the fry in a fry net in their original tank. A pretty good layer of gravel in the fry net (I do about an inch) keeps most other rift lake fish from trying to munch the fry through the net.
