Funny thing is they do sometimes sulk a little bit, esp. the one that goes to a new tank. But even the one left in the original tank may act differently or may be just as usual. I had a few sub adult females in a 300 gallon enclosure some years ago, when I sold 2 the remaining one did go through a phase of despondency, but it's still best to separate dragons due to the severe injuries they can inflict on one another out of the blue.

Another thing I noticed in your pics was the pellets as a substrate. My personal opinion of loose substrates is not to use them. All of the research I have read on this says they can be a health hazard if ingested as it can cause impaction. Impaction can cause paralysis and even death in dragons. I leave nothing to chance when it comes to my dragon's health and wellbeing.
I always recomend a solid substrate like tile, nonadhesive shelf paper, paper towels or, newsprint. You can use repticarpet but keep two for each viv because when they poop on it, it will need to be cleaned(washed) then you put the second one in while doing so.
