My large american toad Bufo used to LOVE worms, but now I throw down a worm, and he acts like it's not even there, but give him a cricket, beetle or small fuzzy, and it's gone!

How can I get him eating worms again? He won't feed off forceps, and will only feed in his viv?

The other toad, Bruce, simply will starve before he will eat a worm, about a month ago, I had to ration my crickets because I couldn't get any for 2 weeks (I had around 40 crickets) and I would cut up the nightcrawlers, put them in hole, in half, dangle them, nothing worked, wouldn't even try to eat one! He went down to a pretty skinny size, I tried to feed him a pinky too during that time, but all he wanted was crickets or fast moving insects, when my shipment of crickets FINALLY arrived, he ate 15 crickets.

Any tips on how to get them to eat worms again? I've got 300 nightcrawlers not getting eaten...

Here's Bufo:



And the picky, "if it's not moving very fast I won't eat it", eater Bruce:



Thanks!
