Great advice, friendly people, and lots of frogs!

I figured the snake that was in your Phyllobates terribilis was up to no good. So I take it this means other predators in the area likely aren't able to cope with the frogs poisons and have learned to stay away?
Exactly. And I don't think anyone has found one of these eating a terribilis, it's just suspected. This is all part of the terribilis article I'm slowly but surely working on for the site. It's about 75% complete now.
