I’ve had my spiny-tail for about 8 months now. I’ve read a lot of information about green igs, but info on spiny’s is hard to find. Few questions ---

How long do they live? I’ve heard 4 years to 25 years... quite the discrepancy.

How fast do they grow and how big?

Are they tameable?

Obviously life-span is relative to care and genetics, and I do believe they can live to be 15-20 (maybe older) given the proper care and assuming there are no medical complications (cancer, egg impaction, etc.)

Full grown size is generally 2’-3’ total length. I can not tell you much about growth rate, as ours was a sub-adult and about 16" when we got her...she is now about 22-23" and we think she will be on the smaller side for the species as she has already laid her first sterile clutch in September, and her growth rate has been significantly slower recently.

Spiny-tails are known for being aggressive, and ours is no exception. While she can be handled, and is handled regularly, she is always quite flighty. Not exactly a lap lizard or whatever you wish to call it. She still will run away when I go to take her out, and usually hisses at me. She acts friendly one minute (once out) and then tries to dart away the next.

Here she is...these pics are from today...Good luck and hope this helps some!
