The black dragon piece is result of F2 from Ban Leang's black dragon line.  In my F1 result, most of the offspring was with platinum scale, however the black color on the part of finnage is not intensive. After get some advise from a Big Sifu in Penang, SH Lee. He advised me a black dragon must have a nice separation between body and fins, some dragon lace at the part of caudal, tick and bright metallic silver scale that able to make your eyes pain. From his advises, I decide to select out a pair of dragon which is roundly same to the criteria . While, my main focus is to inject the intensive black color into my dragon line. Now this is my F2 result, obviously the coloration is improved, i feel that it worth for sharing my experience in dragon's line with all of you.  = ) 

This piece on above was one of my F1 Black Dragon HMPK result, and i chose it as the candidate for proceeds to my F2  project. It was the nicer fish among my F1 fish.  By pairing with an appropriate female fish, i get an amazing F2 result. In the F2 batch, nearly whole spawn coloration was dramatically improved, as the black color of the fries body is become intensive black before the dragon scale coming.
