Your friend doesn't know anything about Flowerhorns. I've been researching the topic of breeding for a while now so I will try to help, though experience is the best way to learn, which I don't have lol.
Breed RD to RD to get some RD, Its the best way to get RD. If you have one extraordinary male that you like make it the center of the project. inbreeding(breeding brother to sister) and back crossing(breeding back to the parnet) to the significant male Dragon will be involved. You should start multiple lines so that you cross lines with each other so they don't get too inbred. As you breed, your strain should get get more stable. The f1s(first generation) will have a smaller percentage of good fries than the future generations. As you go down the generations they should get better. You should introduce a new bloodline into your strain every few generations to prevent inbreeding depression.
Do much research and visit FH forums. I learned alot more at a FH forum in a month than I did here for over a year(no offense to MFK).
Wait for experienced breeders give advise, they have actual experience haha.
