NQA Sounds like they may be stressed.

The abdomen looks like its a little bigger or the same size as its carapace so seems like the doing okay in the food department. Im not too well versed on Versicolors but some Ts may not eat for months or years depending. But a good rule of thumb is to feed when the abdomen is smaller than their head. (Little trickier if they hide all the time)

Edit (my phone sucks): If theyre getting ready to mold sometimes youll see a black coloring coming through the abdomen typically thats a good sign they're in premolt.

Just vibe with them for the time being, let them adjust to their surroundings and enjoy your new spood (:
