Ah, okay. Is there any other place that it might fit? It'd be preferable to have the width be 24", but if your friend who's building the cage thinks it'll be fine then go for it.
The worms and snails should be fine; I'm not sure on the locusts (or are you referring to grasshoppers). You might be able to find canned snails that are canned in water; those are pretty cheap from what I understand and are a good food source provided that the ackie will eat them (they don't always eat dead stuff).
