This was the first tunnel in what is now a thriving ant-city. My son wholeheartedly considers them pets, so that puts us up to two birds, a cat, a whole bunch of fish, a few snails, a crab and these guys (about 45 ants in all, I think). We're raising butterflies starting in a week or so.
As long as nobody eats anybody else, we should be fine.
