Not entirely sure of these morphs.

I built a new rack which I keep them all in separate from my others, does that count as quarantine? And what about the one that the guy said was either a pastel or a yellow belly? You think she's both? I'm leaning towards pastel but she's not nearly as bright as my hatchlings.

Sure, that would work. It's always better to air on the side of caution when adding new animals to the mix. Based on the photo, I'm leaning towards Pastel.
