The pet store was definitely to blame for the Barking Tree frog dying like that. Barking Tree Frogs are like articulated American Green Tree Frogs. I like them a lot and in the past I kept them for a few years. They have such an interesting call too. From a pet point of view, I would take Barking TFs over Greens any day of the week, although Gray Tree Frogs win the battle of the US tree frogs in my opinion.

I'm really glad to hear the rest of your story though. It's very heartening to see you weren't deterred from the hobby by that initial tragedy. I am also glad your Petco is a good one. They're not all that well staffed but I have seen a few that are.
