The 1" of fish per gallon rule is intended for adult sizes. You should figure out what species of angel fish you have so you can check on how big they are supposed to get.
I'm not sure I would keep a pair of angelfish in a 29g either. They get pretty tall and I think they can be territorial.

Be careful! The 1" of fish per gallon rule does NOT apply to puffers and other aggressive/territorial fish. For example little drawf puffers need 3 to 5 gallons each even though they're under an inch in length. Larger puffers are even more aggressive and most of them need brackish water conditions (some even require full marine at differant life stages). Most puffers also need to be kept in species only tanks or they will eat anything they can catch.

Also note Aquarium salt is NOT the same as sea salt (which is requirede for brakish and marine conditions).

Angels also you have to take into account thier height and that they're also cichlids themselves. Like Meghan said they can be very territorial. Give the angels as much room as you possibly can and be very careful about what you stock with them. Small tetras (like neons) will get eatten. Larger fish may get bullied by them as well.
