Heat options in plastic tank?

Injuries can occur if it's not done right. I've never done it.
I find tail structure to be the best/safest way.

Agreed. I've seen people that were so confident they could pop a garter and ended up hurting them, or at best, calling them female just because nothing came out. I don't recommend it. It's not necessary. Not all males have a bulge after the cloaca. However, if it's a male, the width of the tail after the cloaca is usually about the same width of the body before the cloaca. If you look at the width right before the cloaca, and see that the tail isn't as wide right after the cloaca, you have a female. Hope that made sense.
