Whites are tree frogs. Think what they would eat. I don't think fish would be very high on the list. I would think insects(roaches, crickets, mealworms) would be first. I would only use fish for less than 20% of the overall diet. What about ordering crickets or giant mealworms? They can be delivered to your door, cheaply. I can keep giant mealworms in a 5 gal bucket for months.
