I've thought about keeping ants quite a few times..I may get some. I bet they're interesting to watch.I've been waiting for my inverts and lizards to wake up. The lizards are eating so I guess the tarantulas will start to liven up soon. Most hadn't been fed for a couple of months and still aren't interested. While I was waiting I've started keeping ants, they're in the bedroom where its a pretty steady temp, 19c most of the time. Where the inverts are in the loungeroom averages around 15c but drops below that some mornings so they're brumating basically.
