I have an image of the BMI scale for tree frogs and mine are a bit plump but not classified as obese. I am a zookeeper and the zoo where I work feeds our frogs the same thing that I feed my frogs and they aren't obese, either. I cannot get roaches because they spray for pesticides almost everywhere in my city and my frogs refuse to eat earthworms. And I don't get crickets often because out of a bag of 20 I usually only get to feed out maybe 8 and the rest die eventho they have access to cricket gel and cubes. I only feed them one mealworm/superworm every other day, which gives them 36 hours to completely digest that item before they are fed again, which is why they aren't obese. At night the house gets no colder than 76 degrees. I would ask our herps supervisor for help with these issues but she is mostly unapproachable these days because she's also the general curator and is very busy running the zoo. I don't think you'll have an more luck with the pictures than I do--they comply with the proper file type and file size but simply won't load.
