The Sire is a royal blue HMPK with a nice long bodyshape and good topline. The caudal has a nice D-shape with long outer rays. The anal has a good trapezoid shape with a gradual slope. The dorsal is uniform rounded and ideally could have a bit more volume with a broader base. The ventrals have a nice length, volume and single tips. The Dame is a sibling to the male and likely marbled to this pastel color. She has a strong body with a nice topline and very nice balanced finnage (nice D-shaped caudal fin and parallel anal fin).
With this cross I hope to fix the strong bodies, smooth topline and balanced finnage. The offspring (F2) likely will be darkbody (metallic) iridescent with a chance of blondes and marbles to pop up.
