Yes you can feed both the dubias and crickets carrots
I would take the log piece of decor and put it under your basking light - and move the hide piece under the UVB -- you need the distance for your decor directly under your UVB 12-15 inches for a T 5 -- I am assuming you have a T 5 - that log piece is gonna give him different temps - make sure you take temps on different spots of where he can sit -so you dont get temps too high - like at the top of the log its gonna be hotter than at the bottom of it - does he lay on it? Here is a pic of my Zen
Hiccup and Blaze both have the basic same set up and the log piece in the back is from Petsmart - its a resin material - they both utilize this piece of decor in many ways - you can lay it different ways in the tank - I have found the way its in there now is the best - they sit lay and stand against it - sleep under it use it as a head rest etc........... it is amazing to watch them and the way they use it --
