I don't think you could, because it's not poisonous, but the colors say it is, so the lizard wouldn't touch it. You could try, I've never tried so this is all theory signed Kaguya Kaze.
Guppies are a good food source if there are enough of them, but you must also feed them crickets regularly. While not suggested, they can go for 2 weeks without eating. You must have a cover, as they will climb up the tank corner to escape.
Do not feed your toads grasshoppers, as they are hard to digest and sometimes poisonous to them. Do not feed your toad meal worms, as these larva possess hard shells which fire-bellied toads have a hard time digesting. Most toads can digest small meal worms and grasshoppers occasionally but should not be your toad's primary source of food.
Crickets and guppies are your best bet for healthy, happy toads. Loss of appetite, bloated abdomen, laziness (this may be due to lack of nutrition), and cloudy eyes can be signs of disease. Clean your frog's tank and contact an expert if any of those occur.
