They are iridescent for sure, especially in the sun! I am sort of spoiled in the iridescence department thanks to my Brazilian Rainbow Boa, but the Antaresia are really surprising with that quality. I'll get a full-body photo of Cricket next to something that makes for an easy size comparison, though it'll be a few days because today was feeding day. I still laugh about this year-old snake muscling down a large mouse pinky.
And Vivi, the completionist in me considered a Spotted, but I think I am content with these three. If I get another snake at all, it'd likely be a Dumeril's. But aside from occasional twitches because I love all of the Australian pythons and would love a Bredli and a Papuan, I feel like I'm at a good place snakewise. I have the right number to set up a very attractive 'snake wall' of PVC enclosures in my study, I can handle my guys enough to keep them habituated to me without over-handling, and I can provide enrichment to this crew as well. As is true for all of us, I think, there's always a bit of a yearning for 'just one more', but I think I am at a good place as is.
Plus I always keep unexpected rescues in the back of my mind. I have at least one friend with very fragile health, and I know for sure I'd end up with his python if he becomes unable to care for it.
