Today was a milestone in my getting ready for winter because it is hard to get live foods here program. My B. nebulifer took the longest to catch on, however all of my Bufo now successfully eat worms. My B. woodhousii picked it up by the second feeding, my lone cognatus took to it right away. The nebulifers took about a week, but they figured out the sticky tongue bit does not work well- just get in the dish and grab them! They are not picky either- nightcrawlers (chopped in half for the smaller critters and those red wigglers that nothing seems to like are all eaten easily. The trick is to keep the worms in a food dish or feed your toads in substrateless tubs.
May not work for everyone, but I am glad I have added yet another easy to get back up food for my pets.
