Aussie, Gecko's losetheir tails too, after they losethereoriginal tail, they regrow another but it lacks pattern of the original. The regenerated tail is onlyconected by softcartilige, not bone. It can be dropped again in defence, and grow another provided its sufficiently nourished. Id be a bit sus that a gecko being handled is not happy. Rather, It will be stressed and may not eat.
Avoid handling gex unless nessesary imo.
