So, my colony of Formica rufibarbis has reached the size where the hang out permanently in the outworld, and, the outworld's pretty small. As such, with being such quick ants, they escape, a lot, when I feed them, and last time, three fatalities had occured.
I've already ordered a new outworld, but it won't arrive for a bit yet, so, what can I do? I've been thinking about slowing them down in around 15 degrees celcius before feeding, but I'm worried such frequent temperature fluctuations would adversly affect my ants.
