I have a question about my Crested Gecko.?

Question

What does it mean if the bottom of their chin turns red? Does it mean they're upset, or is it just part of their life?

Answer 1

Crested Geckos do this when upset and mad or when being arrogant and showing off- for you or for a potential mate (even though there might not be any available mates for miles!). My dragon does this a lot, but he is a cocky butt-head! The vet I work with says that this is the best part of having lizards, because of their personalities.  

Answer 2

well me and my freind have been studing lizards and he did some resaerchon crested and it meens hes upset, or depressed i THINK
