They would point at the end. I like the tails to spread to a point at the end. Not a whole spreaded tail, or a completely pointy one.
I have a dt geno (originally thought it was HM, but looks more VT) and a VT with a great spread in her caudal. Was hoping to give this same pair another shot.
As far as colors, my male has a bit of dragonscaling and the female has a bit of irid to her. The male has a small bit of BF pattern, but I don't expect this color to pull through in the fry.
If we are made of cells, then a scientist who studies cells is actually a group of cells studying themcells!
