Thank you, guys. I did email the website, but it looks like it hasn't been active in a few years. I also tried emailing the Guiness World Record people. Most of the time when I tell people how old Joe is, I'm told my folks pulled the ole' switcheroo on me when I was young and the original Joe is likely long dead. First off, Joe is at least three or four times as big as any fire belly I've ever seen in a pet store. Second, I've had him long enough to recognize his patterning so I know fort a fact it's the same animal. When I recently asked my mom is she had ever switched out a frog, she was legitimately offended/hurt and assured me that had never happened (I apologized, I love my mom

).
Honestly, it really isn't a very elaborate setup. The care sheets you read at PetSmart are more detailed than my care. My frog lives in a critter tote-style tank (we get a new one every few years) that has some pond gravel in it and a basking platform. Literally as basic as you get. The water is changed/refilled as necessary and I always add four drops of some of that water-cleaning stuff that prevents algal growth. Joe gets two or three crickets at a time a few times a week (if I put in as many as I did when I had two, he wouldn't be able to swim amid all the drowned crickets). IMO fire bellied toads are the easiest reptile/amphibian pet to care for.
