I bought the exo terra with my red sided but the warmest ive seen it is hot end 24c ambient,17c cool end ambient... The snake is always cold to the touch. The exo terra is the large. Am i used to heating a water monitors viv,burmese viv and worrying to much? Does it need a hot basking spot? It's a big viv for a little snake and im worried about the heating. I know it's a none tropical snake. When i picked it up from the shop it was warm like picking up a florida king. Any advice im all ears. Thanks
