You can definitely tell there is heckel blood in those fish. The patterning, the face shape, and the overall body shape are dead giveaways. I used to have heckel x turks and they were some of my favorite fish.
John, do you think the spotting from the eruption parent would come through in future generations if you bred the siblings to each other, or back to a parent? Or is it likely they'll all be striated like this?
