If we used a 20 gallon tank we will do one more move (to a 40 gallon or larger tank) at 4-5 weeks of age.  Daily water changes are still a must at this point.  We also start to introduce crushed flake food once they are almost 4 weeks old.  Very little at first, and then more each time and less baby brine shrimp.  At 6 weeks they are approaching dime size (that's the size of their bodies with fins) and we slow down the water changes.  Now every 2 to 3 days.  We do this because they will be going to their new homes shortly, and we must assume that the new owners will not change water every day.  This acclimates the fish fairly quickly to water conditions that they will be getting from their new home.  This makes our angelfish much easier to acclimate and adjust to their new surroundings!  At dime size they are ready for us to sell. We now will hand pick the best 10% of the spawn to keep and raise for our future breeders.  We choose for body shape, straight fins and color.  This way we are assured to have the best breeding stock available year after year.  This will usually result in about 50 to 100 babies and we will do the same thing once they hit quarter size (our medium selling size). At quarter size we are sure which ones we want to keep for our future breeders.
