You can't grow out angel fry to a sellable size in a 29 gallon tank with their parents. Like I said before, the problem with cichlids is that if you're raising out fish to sell, you're going to need more than one small tank.
A lot of people get into fish breeding to make money but that's a hard thing to do. Even with lots of food and water changes, it's still going to take you 10 - 14 weeks to get most cichlids to a size where you can sell them. Now figure you need a decent-sized grow out tank, plus food and water for 10 - 14 weeks... are you really making any money?
Just some food for thought.
