So I went into the local petstore to buy some live food for some Myrmica Rubra. Colony has 4 queens and about 30 workers. I realised that I actually had no idea what food I should feed them. Fruit flies, crickets, meal worms or some sort of beetle? I thought Fruit flies but I'm not sure how to keep them. They'll only last a month before they die. Will they breed among themselves? What should I feed them to keep them alive? Most of my previous colonies never really grew past 10 workers. Honestly, I'm stumped about what to do with livefood.
