This sale is mostly comprised of Zolnixi and Lupora, although there are occasionally Faeloras and Ryoris somewhere in there.
I'm selling most of the adolescent pets in my hatchery (none of the hatchlings, since I don't have the funds or resources to genetically test them.) The first couple of pages are pre-named (at the time I got them, I didn't realize I would be selling them later), and their prices are based on their visible traits.
In pricing, there may be a few exceptions here and there. For instance, the already-named pets in my hatchery are somewhat cheaper than the unnamed ones, or I just changed the pricing system here and there.
