I thought this would be a good place to post this, I got my juvie beardie a new bulb since his blew, the old one kept the Viv at 100 degrees but this new one only keeps it at 80. Now he's black all day while basking which he's never ever done before, should I get a new bulb that emits more heat? I don't want him to be stressing himself all day
Which basking light are you using for him, what wattage is it?
He wont be able to digest his food & will be lethargic only being kept at 80. So, I would definitely
recommend getting a higher wattage bright white basking light, such as a halogen, to produce more heat, absolutely.
He is dark because he is trying to soak up any heat that he can.
