Hello all, beginner back with some more questions. I've had my three Darts for three months or so now, and they've been doing well -- active, eating, etc. Finally got the fruit fly culturing under control, and just starting my first real vivarium build to improve on their habitat!

I have a question about one of my frogs, though. Hopefully someone can help --- it's a blue/black Auratus, I think. The past two days its throat is swollen or puffed up - all the time. Not inflating/deflating - it is constant. The frog is acting normal, eating and moving, but I'm not sure what the throat means. Google led to too many ideas to be of much help. Does this mean it is a male? Is it normal, or a cause for concern? Any advice would be greatly appreciated.
