Fighter incross for better Anal fins?

Hi friends,
what do you mean? The idea is, to cross a fighter male or female in the ctpk line to get shorter Anal fins.
But the problem will be to get a good fish for this idea.

Hi friends,
now I have the first Marble in my Copper Line. Until yet I believed, the line is marble free,
but it is no problem for me. I like him. What you think about him?
