Find a new home for the other fish, keep them together, and feed them lots of good food. In about 6 months they should have the routine down and be spawning regularly. Maybe you can make a little of that money back that we sink into this hobby! Angelfish are on of the few fish that are easy to breed, and can actually sell for a reasonable amount of money. If not.... well then you will have LOTS of angels here before too long.
