Out of the two, I would pick the first one, it has better pearling, nicer color, nicer fins and also has a decent KOK potential....just looks like you have to pump him up...
I would buy some fry from a reputable source and try to grow out a masterpiece. Look at flowerhornsfrombeyond.com. I just bought some nice red dragon fry for $5 each. They should be about 5" in 4 months. THey grow very fast.
i'd go with first male and first female. i heard the more the centerline goes down the side the better. so with that said thats why i said 1st and 1st.
