Hi mate,
Welcome to the forum
Yep give your scorps some time to their enclosure. I'm sure they'll be comfortable and start eating when they are ready.
My youngest H. spinifer female has been hiding out for 2 months since she's with me.. so i just leave her alone except the occasional misting and refilling of her water dish..
Finally.. she started eating few days ago
I'm sure yours will do just fine
Feel free to post your questions.. friendly peeps in this forum!
