They look good !
I have not raised peacocks before but several other cichlids.
Lower the water level in their new tank if possible so it is easier for them to get to surface .
You can also just add new water instead of wc till tank is full which will help them grow a little before you possibly suck them up !
Baby Brine Shrimp at least 2x a day will expedite the growth along with getting them to a good powder grow food by 3 weeks if possible.
I still feed BBS as long as I can[too many fry to feed forever] but supplementing with good quality food is important.
Steady waterchanges with matched water on the regular once they get going...2-4 weeks old..
What size tank?
I would do Bare Bottom [BB] with a sponge filter and eventually PVC pipes for the fry to explore in.
