Dragon names are tricky... I mean, I've heard everything from Hiccup to Syzdothyx.

[No, he didn't just hack up a hairball there. It was a name.]

Generally they'll either tell you their name... or disagree with whatever name you try to give them until they find one they like.

As for gender... dunno on that one. Some dragon types have specific coloration. Like Trey up there. Browns are always male. But these... I guess you'd have to ask when she? is older.
