Feeding an American Toad and Northern Leopard Frog?

[findiviglio]

I found this article about why goldfish are bad for african clawed frogs, I'd assume its the same for toads:

Can Clawed Frogs Eat Feeder Goldfish? | Animals - PawNation

and another one about feeding goldfish to turtles:

Feeding Fishes to Amphibians and Reptiles: the Goldfish /Vitamin E Question - Part 1

as for spiders I have no idea!! Now you've got me curious

Hi, thanks for referring my article re goldfish/turtles. Minnows are a good food source for leopard frogs, use small individuals, not more often than once monthly or so; earthworms ideal as basis of diet. they readily accept spiders, but I would avoid, bite potential for frog and frog keeper. m let me know if you need more info, best., frank
