should I put her in a bigger tank?

Hey guys.
I have a BP who I adopted yesterday. I have two tanks, one current and one for when she gets bigger.
Her current tank is 12x12x18 with fake plants. It is around 82 degrees F. Humidity is 40-50%. I have a large water bowl she likes to swim in and a drip system. There is a small heating lamp and small heating pad on the bottom. It is not too hot and I can easily touch it. The bottom is wet from trying to keep it moist. Aspen shavings are the substrate. Mangle is about three feet long.
I have another tank. It is about 50 gallons. It has a heating lamp, a few hiding places and is huge.
What do you all think?

Well from seeing the picture in the other thread, most definitely get him into the 50 gallon. 12x12x18 is more of a GTP cage. And as I posted in the other thread, there are a lot of other options too. I got a beardie in a 55 gallon tank and my god they weigh a ton. If you got a PVC or HDPE cage, you will be amazed at how easy it is to keep temps and humidity set right plus they are much more secure, lighter and easier to clean.

She's (Probed and confirmed to be female) is in the 50 gallon now. She appears to be much more active.
Can I keep the new cage on the floor (The floor is made of stone)?

Welcome to the forum. You don't have to post multiple post with the same question, it will only lead to confusion. Admin could probably merge them for you

You said in your first post at the top "The bottom is wet from trying to keep it moist". Be careful your substrate is not constantly wet, your snake could develop scale rot from this. Your 50 gallon should be big enough to add a humid hide or some moist sphagnum moss in a corner to help keep your enclosure's humidity up.
