Feeding regimine for fire bellied toads

[Jack]

I'm interested in fire bellied toads, but want to limit my trips to Petco to get crickets and so-forth (preferably no more that once every three weeks). I also would like the keeping of feeders to be a simple as possible, as I'm going to relegate most duties to the kids (their frogs).

I wanted to know if the following feeding regimine would be acceptable for firebellied toads:

Feed crickets for 1-2 weeks.
Feed meal worms and earth worms for 1-2 weeks.
An occasional fish (firebellies would be housed in a rivertank with some small fish).
During the warmer months (approx. 7-8 mos. per year), all feedings could be supplemented with wild caught bugs.
During warm and cool weather (approx. 10 mos. per year), all feedings could be supplemented with gutloaded slugs (gutloaded with my dog's dogfood).

Earthworms and mealworms are easy to keep, as I can keep in the outside refrigerator. Crickets are more problematic, as they take some care and if not used fairly quickly, they could grow too large.

This regimine would mean I would only have to go to Petco about once every three weeks, possibly less often in warmer months. I would gutload all feeders and would dust appropriately. Any thoughts?
