In my experience, a sorority is good for housing females you don't plan to breed. They tend to chase each other here and there, and don't get into peak condition like they should. Keeping them in solitary confinement and feeding them VERY well several times a day will spark egg production like mad, especially if you let them see a male for a few minutes a day.
That being said, can you answer all of these questions?

14) What items do you need for the spawning tank?
15) What temperature should the spawning tank be?
16) How do you properly introduce the breeders?
17) What do vertical bars mean?
18) How do you know when to release the female?
19) How can you tell the difference between normal and abnormal aggression?
20) When do you remove the female?
21) When do you remove the male?
22) On average, how many eggs are produced per spawn?
23) On average, how many fry usually survive to adulthood?
24) How long does it take eggs to hatch?
