If you want to raise some next time try the following:
Hang a piece of slate near the top of the tank.
When they spawn remove the eggs to a small tank, add an air stone and meth blue.
Don't feed until they are free swimming.
Feed brine shrimp nuplii in the small tank for first week.
Move to larger bare tank and feed the hell out of them and change the water every time you walk past.
When I was breeding angels blacks were the most expensive and sold the best.
If you breed black to black you will get at least 25% double blacks. These look the best, grow slower, are weaker and are more likely to die, so if you want to raise them it is best to raise "the runts" seperately.
If you do this the parents cannot eat the eggs. You can then keep a male double black and breed that to a gold female double veil tail and you will have all strong, good looking offspring with good fins and everyone will want one. Welcome to the world of angel breeding.
