I think there where quite a few babies produced with no axanthics so while it's possible they just missed on the het VPI X TSK cross (can’t remember if homozygous or het on the TSK side) the odds where pretty low if the het VPI was a real het.

The good side of lower prices is that more people now have the resources to try something like this. It would still a fairly pricey endeavor to dedicate an adult pair of visual morphs to just to be certain. You would be tempted to use those animals for a more profitable project.

It also might be complicated by the fact that the original cross was done some years ago and if you where to pick up one of each line today it could be a descendent of the original cross and het for the other without you knowing it. There may actually be unidentified double homozygous animals out there already.
