Why? Is this another "tetramorium are technically invasive so I am just going to kill them for no reason"? The best livestock convert stuff the consumer doesn't eat into stuff that is consumable, such as Mealworms, superworms, fruit flies, flour beetles. Sorry for being aggressive, this idea is just really, really daft. Your going to have to feed the tetras food too, might as well just get more mealworms for everyone, instead of just giving the tetras mealworms and then feeding the workers to other ants. Anyone with basic biology understanding will know that energy decreases the higher you get up the food chain.
