When owning a Beardie you need a cool spot of 75-80 and a hot side of 100-110
A 150 watt bulb should do the trick. A bearded dragon needs about 95F to 105F in the basking spot and 75F to 85F in the cool end of the tank.
You could - but due to the fact they CAN grow to 18 inches - you're better off with a 4ft vivarium. They're nomadic - in that they prefer space to move around instead of just sitting in one spot.
They Live in Central Australia in Mostly Desert Areas
bearded dragon temperatures vary in their tanks. The hottest spot where they bask should be between 100-110 degrees. the cooler end of the tank should be around 80-85 degrees
They eat in their normal habitat temperature which is 100-110F for the basking spot and 75-85F for the cool side
If your bearded dragon is female and old enough, she might be trying to lay eggs. It's best that you have a separate digging box filled with substrate she can lay her eggs in, as substrates like sand, calci-sand, wood chippings, gravel, and other similar substrates can cause impaction. However, your bearded dragon might also be trying to find a better basking or laying spot.
Cool Spot happened in 1993.
The temperature for the basking spot you create on one side of the enclosure should be around 110f for juveniles and can be around 95f for adults. The cool side of the enclosure should be around 85f during the day. Night time temperatures can fall as low as 65f.
Cool Spot was created in 1993-06.
First off make sure you have nothing smaller then a 50 gallon fish tank for a Bearded Dragon. You should have 2 temps in your tank. A basking spot with rocks should be between 100-110F with a cooler side of the tank (along with a UBV light) being between 75-85F
