Grandfather VS Grandchild

Grandfather

Grandchild

I don't really know what motivated me to compare them. I just want to.

I will point out the differences that are most significant to me.
[Feel free to comment if you want to add more]

Dorsal
For me, both are sailfin because the dorsal fin width is at least half of body length. Dorsal bases (where the dorsal is attached to the body) are still wide.
Grandfather has a nicer shape because its more rectangular. More broad
Grandchild has a broad dorsal too (check out the base). However, the shape doesn't give it that impression though.
First rays play an important role. Grandfather has an abrupt increase in dorsal ray length while grandchild has a more gradual increase in dorsal ray length. Hence, grandchild's dorsal shape is more smooth and rounded.

Body
Grandfather has a typical betta body
Grandchild has a thicker, stockier body...this evidences a strong dt background (even though both of his parents are singletails carrying DT)
Toplines are both smooth.

Ventral, Anal, Caudal
All are pretty much the same to me. The shape of the anal fin is uniform for the line. I'm seeing a trend to a more symmetrical look.
Caudal is still rounded. I will have to work on that.

Color
Honestly, I have no idea how Grandfather carried marble. Grandchild's father is a copper marble. When Grandchild was younger, he was a solid copper then marbled out into his current color. It pretty much stabilized now.
Grandfather showed the typical black base my coppers have.


The Winner
For me, Grandfather still wins. I am planning to cross Grandchild to Grandfather's two DT daugthers. They are Grandchild's aunties. I hope to get more of Grandfather's blood into the next batches of fry. I am yet to see a reincarnation of Grandfather but I am hoping.

UPDATE (10/23/2013)
I see fry from Grandchild x DT aunts.
They are almost all DT! Grandchild really has strong DT blood in him.I crossed the aunties to other related fish. They threw in some singletails. I'm planning to bump the DT produced by him to these STs. I hope for more Sailfin HMPK to come my way!

Cellophane HMPK male (descended from Red Dragon x Marble)


Melano PK male (descended from Metallic Steel HMPK x Copper PK)


Grizzle HMPK male (brother to Cellophane)


 Metallic Steel HMPK male (brother to Melano)


Copper PK female (niece of Melano and Metallic Steel)



Black Lace HMPK male (sibling of Copper PK female)


Metallic Steel Blue Marble (sibling of Copper PK female)
This one has a really promising dorsal but I can't say that for the rest of the fins. This fish is related (albeit, very, very distantly) to my current Copper Line. I would say the line is really inclined to broad dorsals.
