Determining Age?

[hattori]

Is there anyway to determine the age of a newt? I have 5 Chinese Firebellies that I'm wondering about. Two just SEEM older to me - they're a bit more bumpy and not as dark in color. One's pretty small, so I'm assuming it's younger, and two others are ageless.

Is there anyway to figure that out?

Once they are adult, no, it´s impossible to estimate an accurate age. They could be 3 years old or they could be 12....
