The way I moved my fish from my 10 gallon to 55 gallon is I just netted them, and since the tank was only 10 feet away from the 10 gallon, I just netted them and carried them from one tank to the other and plopped them in. But, you could net them, then get them in a bag with some tank water in it and blow it up with some air and let one float at a time like that so they dont get to stressed....
Or, depending on how big the angels are, if you don't want to stress them very much you could use a net and a drinking glass or jar, and chase them into the glass/jar so that they would never be out of water
Move them with a net or like the 'cute' drawing (lol); making sure the water temperature is the same. If you are worried about the water/bacteria balance, use some bacteria supplement (like Cycle or Stability) until your fish are settled. I hope this is good advice; I have never 'cycled' a tank w/o fish in it, but I use the bottled 'bacteria' products every time I upgrade to a larger tank, or change my gravel etc., and I have NEVER had fish loss.
I would not recommend using any chemicals. As to many chemicals can be bad for the fish...Just a thought if you were thinking of using bactera products. IMO if you are in that much of a rush that you can have the tank cycled than its not ready to move at all.
