never spawned rams, but with my apistos the eggs hatch in ~2 days. They go free swimming about 5-6 days after hatching. A little over a week from eggs being laid to proud momma parading them around the tank.
Your rams will most likely eat the eggs/wiggler/fry because......well that's what rams do the first few times they spawn. I would just let them keep at it untill they get it right. If you get impatiant, then you can pull the eggs and hatch them artificially, but watching cichlid parental behavior is half the fun for me. They will continue to spawn repeatedly every 2-4 weeks. Feed the female a varied diet of frozen foods to condition her in-between spawns.
You can try and raise some in a breeding net, but if you're serious, go buy a 10g tank, cheap heater, and a sponge filter. Leave the tank bare-bottomed, do weekly or bi-weekly water changes and feed baby brine shrimp (live is best but frozen can be used also) in small quantities as many time a day as you can.
Good Luck and Congrats. Let us know what the ratio of blue to gold babies turns out to be.
