Hiii, my name is Krystal. So i have a bearded dragon his name is Viserys, i got him around the end of July last year, the store didn’t know his age so i rounded it to two months. II bought the tank starter kit that came with everything when i first got him but recently i bought a thermometer & it says that the tank is 75° with the 75 watt lamp, i noticed he got darker & he’s always hiding under his hammock or going in his cave early so i upgraded it to 100 watt, that didn’t do much of a difference & so i bought the 150° that made his tank to 85° for a few days but dropped right back to 75°. I have the dual dome lamp with one side his basking light & the other side is his uvb light. That’s all i have set up for him. I’m going to upgrade his tank to 120 gallons & buy two heating lamps & the Arcadia UVB. I was wondering if that’s all i need because i don’t know why his tank temperature keeps dropping back down.
