And the eating alone thing might just be a "personality" (toadality?) quirk rather than a stress response. Some of my hand tame rococco toads who ALL went crazy with a feeding response when it was crickets in the feeding tub would ignore fuzzies and mice if I was watching. That was the only thing they got to eat in the tank and they liked to be alone--I could watch from a distance but couldn't be anywhere near their tank or they wouldn't eat the mice.
