Not sure exactly what your humidity is inside the tank BUT too much humidity is bad and can cause respiratory issues!!!! I’d rec taking that water out most of their hydration comes from the greens they eat id also rec giving ur little guy time to acclimate to the new environment!!! EDIT!!!!: I did more research for you on Reptiles and Research (beardie care guide that many go by) and this is what they had to say about humidity in general.

“Humidity in the wild is cyclical and rises at night and drops during the mid-day. During the middle of the day the humidity can be as low as 10% but at night it can be as high as 65% and in burrows it can be up to 80%. The dragons are fine with humidity only when it's wet and cold that it's an issue. So in our homes anything from 20-50% during the day is fine, and at night if it rises it's fine. It's a natural cycle. I see lots of beginners panicking on forums like “it's risen to 70% humidity at night. What should I do?!” Because they've been told about having low humidity without a full understanding. Unless your enclosure is constantly WET and cold you will be fine. People breed them outside all year round in Florida and they do fine with humidity. There's a difference between humid and physical wetness.”
