Sorry if I'm being redundent. I read some of you feed Blood worms as a side food. How do you get your frogs to "see" this food? If frogs are not used to this food, how do you introduce it so that they know its food? I put some on the wet paper towel-no go, I put some in a tiny lid with water-stuck up their noses, I put some on plant leaves that were being rained on-didn't even look. In each of these instances, the worms were twitching. But the froggies didn't seem to notice.
