It's my third 09/10 more antipated pairing. They are 2004 littermate, in 2008 they have both proved to pass there striped squared tail in a dominant way with unrelated wild type colomnian's. Last year the female never ovulated, I hope this year it will worked out and that I will get the super form !
For the moment,I call them X tail since 'square tail' is refering to the recessive blood line.
