Nice looking pair! Flametail is a partial pinstripe flame (maybe a harlequin really--depends on how the patterning on his limbs develops as he matures) and Nuala is a dalmation flame. Flame is a pattern morph, not a color morph, so the red coloration doesn't have anything to do with it--a flame simply has a color on its head and dorsal area that is different from its background color.
