So I went to the NARBC in Arlington yesterday and got a (low white) disco fire (he's on the right in the first picture)!
It's a male, hatched May 15, weighs 132g, produced by SMS Morphs. He doesn't have a name yet, but I'll think of one eventually. The last two pictures show his colors the best. He just shed the day before I picked him up, too, so he's very bright! The other one that was there, from the same clutch, had more white, but I opted for this one because I like the slightly muted colors more.
