I'm currently raising about 15 or so platy fry in a 10g. Unfortunately the mother is not doing well and may not be around much longer. She is in a hospital tank and I've been treating her for hole-in-the-head disease. She got sick shortly after dropping her fry, so I'm worried they may have caught her illness, but they all seem healthy. 3 weeks old and already showing colors and patterns! Pretty fun to watch them grow up!
Sorry to hear about your momma fish.
