That's good! It sounds like Gorf is just having some trouble getting her food or recognizing it, as you said. I think the metal ones are okay for reptiles who will simply eat off the tongs, but since frogs always lunge, I don't think they're safe for them. I use bamboo tongs for Truffle and my WTFs and I haven't had any issues. Truffle will even wrestle with them while chomping down on a worm sometimes.
