I've done carnivourous plants in an aquarium inside. They are quite nice and you would probably have better luck with them than desert plants. You don't need to feed them insects. Go to Sarracenia Northwest, it's an online carnivourous plant site. They have bunches of information as to what the different plants need to survive. The one I set up in an aquarium was a tropical bog garden. But you might be able to get some larger specimins for such a big container, that would be cool, giant pitcher plants indoors! At any rate Sarracenia Northwest is a good site for learning something about the plants. You could also find a local nursery that has water garden plants.
