I just got my trio of fire belly toads about a week ago now and I noticed that when I feed them, only one of them seems to have a real appetite. Arnold will eat and eat and eat (I'm serious, I don't think he'd ever stop), but the other two will eat about 2 crickets each and then they are done. I figured maybe since I was feeding them every day, they weren't hungry (even though Arnold was still eating). So, I waited 2 days. I just tried feeding them again, and again Arnold was scarfing them down, and the other two ate about 1-2 crickets and then wouldn't eat anymore? I mean, they're eating, but they are just not eating very much? I also don't want to just leave a bunch of crickets in there because I'm afraid Arnold will eat all of them and the other two won't really get any. What should I do? Or does this sound normal?

Thanks!
