....didn't you take -any- advice on your other thread about not breeding?
1. You might end up with fry no one wants
2. You don't know any of the genetics about your fish
3. It'll probably end up like this. VTs with DT geno, spawn mom with a vtdt male, you'll probably end up with some VTDTs. Not that they'll look nice since we don't know what the finnage of the parents are like.
