No and i agree like diet lighting etc,i keep my basking end between 97f to 100f and i keep mine indoors,i use megaray uvb bulbs and i have a cool end of 78f to 82f and if my rhino dont want to bask and is getting to warm he can retreat.On the other hand i check my rhino's body temps when he's basking and his body temps right around 92f to 95f and he seems to like it.Now my cuban his basking spot i keep at 90f and he loves it and he also has a cooler end as well,and both cuban and rhino get the same diet.This works for my cyclura's.
