Hi,
I agree on the shady.
He shipped USPS and didn't feed for three weeks because "he knew he'd be shipping them"
You have had them only 10 days and have moved them to different tanks already - be happy they are eating.
Use a hook or a water bottle and touch the top of her head gently when you are going in the tank to do anything instead of feeding if she is in strike position. That should make her draw back and snap out of feeding mode hopefully.
