viv is your tank/set up/Vivarium
you need to have alook at the lights and have a rethink asap, they arnt good for beardies. i know its a pain in the ass and costs alot but it will help.
flourescent tube the arcardia 12 or the reptisun 10 are good tubes.
secound the red heat lamp you have please chage it to a normal white light thay give off the heat he needs. for night time if the temps get a little low a heat mat stuck to the side of the viv will be fine.
carrots are not too good for beardies it stoped them from absorbing the calcium they need, i do give mine some once every two weeks as a treat as they do like it.
sorry for rambling on about something you didnt really ask but its things you need to know to have health beardies.
